1. INTRODUCTION

1-1. Introduction

Thank you for your Purchase!

This manual describes the functions of your counting scale and how to get themost out of it. Read this manual carefully before use.

Features

The HC-i counting scales have the following features:
The scales have a high internal resolution for a wider range of counting applications.
 HC-3Ki / 6Ki / 30Ki: 1/600,000
 HC-15Ki:
1/750,000
 There are the following ways to enter a unit weight (of the sample piece).
 The way to weigh a fixed number of samples like 5 pieces, 10 pieces and so on.
 The way to weigh the desired number of samples.
 The way to store the desired unit weight directly using the 10-key pad.
 The way to recall the stored unit weight from ID memory.
 The way to send the desired unit weight from a personal computer.

 Three UNIT WEIGHT BY LED's will navigate you to enter a unit weight easily.
 ACAI (Automatic Counting Accuracy Improvement) supports counting byrecalculating the unit weight when a sample is added. Therefore it is possible toreduce the counting error.
 The scale can show information for piece count, weight, unit weight and comparator
result at the same time.
 UP to 99 ID memories can store ID numbers, unit weight, tare weight andcomparator limits.
 Comparator function:
 Compare a count or weight Comparator limits can be changed using the 10-key pad.
 Comparator relay output is also available using an optional interface.
 Accumulation function for counting.
 Optional RS-232C interface to communicate with a personal computer and printerexpanding the counting application.
 The optional SLA (sealed lead acid) battery is useful for portable operation.
 The display unit is detachable from the scale base (approximately 60 cm). The
distance between them can be extended to 2m by using the optional cable.

51-2. Unpacking
 Unpack the scale carefully and keep the packing material
if you are likely to transport the scale again in the future.

HC-i SERIES In the carton you should find this manual plus:
 The counting scale.
 An AC adapter (check that the AC input rating is correct).
Remove the protective packing materials from aroundthe scale and between the pan and scale casing.

1-4. Setting Up Your Scale
1. Place the scale on a suitable weighing surface (see “Best Conditions For Weighing”
below) and turn the adjustable feet until the spirit level shows that the scale is level.
2. Plug in the AC adapter. The AC input
requirements could be l00, 120, 220,
230 or 240 Volts (50/60Hz) dependingon the area in the world, so pleasecheck that the adapter is correct. Earthground the chassis if you think static
electricity may be a problem.

Earth terminal
3. Press the ON/OFF key to turn the power ON.
All the display symbols are displayed.
Then the display turns off once, and zero will be shown with the ZERO indicator.
4. Press the

ON/OFF

key again, and the power will switch OFF.

 Auto-power off function
It is possible to have the power automatically switched OFF. If zero is displayed forapproximately 5 minutes. See “9-2. F-Functions” and set the F-Function f-04-05 at“1” to enable the function.
5. Switch the power ON at least half an hour before use so that the scale can warm up.

Detach The Display Unit

Remove the display support plate first. Then, retrieve the cable and attach the display
support plate again. Refer to the “15. OP-08 EXTENSION CABLE” to remove andattach the plate.

Best Conditions For Weighing The Scale must be level (check the spirit level on the scale).
 Best operating temperature is between 20°C~25°C / 68°F~77°F at about 50%~60%
Relative Humidity. There shouldn’t be large temperature fluctuations.
 The weighing room should be kept clean and dry.
 The weighing table must be of a solid construction.
 Corners of rooms are best as they are less prone to vibrations.
 Don’t install the scale near heaters or air conditioners.
 Don’t install the scale in direct sunshine.
 Try to ensure a stable AC power supply when using the AC adapter.
 Keep equipment containing magnets away from the scale.
 Warm up the scale more than 30 minutes before use.
 Ground the scale chassis for electrostatic discharge if the weighing conditions
warrant.

Calibration

Calibration of the HC-i is required when the scale is initially installed. Please see “8.
CALIBRATION” for more calibration information.

1-5. Simple Operation Mode
If desired, the HC-i scale can be set in a Simple Operation Mode. Set the F-Function
f-01-01 to “1”. In this mode, only front panel keys that would be used in “3-3. Unit
Weight By a SAMPLE” counting operations are active. All others will not operate. The
following keys are active in Simple Operations Mode:

6. USING THE M+ MEMORY

6-1. The M+ Memory Function

 The scale can accumulate count data by pressing the M+ key, or automatically(see the next page). It also keeps track of the number of times you add to the total.
 When you view the total by pressing the TOTAL key, you view the number ofpieces accumulated and the number of additions (how many times the total wasadded to). Please see “6-2.” and “6-3.” to view or clear the total count.

Adding Using the M+ Key When stable count data is displayed:
1. Press the M+ key.
The scale will beep and the M+ indicator will
blink for a few seconds.

M+ If the scale beeps 4 times, or the M+ indicator
did not blink, then refer to the note below.

COUNT

 The M+ indicator will stay ON while there is countin memory.

TOTAL

888.81123

2. Press the M+ key every time you want to add to the count. Remember that you
may only add the count data once – the scale must return to near zero before it will
let you add again.

 The M+ key is accepted only once for each stable count data.
Once accepted, the M+ key is disabled until the display returns
to less than +5d (1d = 1 weighing division).
 If f-03-02 is set at “1”, then the M+ key can accumulate both
positive and negative data. Once the M+ key is accepted,
weight data must return within ±5d before the next accumulation.

To Erase the Last M+ Addition

1. Press and hold the C key, then press
the M+ key – release.

Automatic M+ Accumulation Mode

 M+ Accumulation can also be done automatically each time you count a different
batch, As soon as you have a stable count, it will be added to the M+ memory andthe scale will beep. The weight display will have to return to near zero before
another count can be added.
 Automatic M+ accumulation is set by F-Function f-03-01 to “1”.
 Only positive counts can be added. If F-Function f-03-02 is set to “1” (to accept
negative count data), it will be ignored.
 Once there is an automatic M+ accumulation, the display must return to less than
+5d before another count can be accumulated.

6-4. The M- Function

 The scale can subtract count data from M+ memory by using the  key.
 Set the F-Function f-09-01=‘1’ to use the  key as the M- key.
 This function is not to clear the last M+ addition, but to subtract count data insteadof addition. The number of additions is increased.
 There is no automatic M- function.

7. COMPARATOR FUNCTION
 The scale contains a comparator function that checks the amount on the weighing
pan against set acceptable count or weight limits. When the comparator function is
activated, “HI”, “OK” or “LO” indicator  will be displayed.
COUNT

88888100

 Before the comparator will work, Upperand Lower Limits must be set (seebelow). The limits are set by count or

8. CALIBRATION
 Calibration of the scale is required when it is initially installed, if it is moved often, or
it is moved a substantial distance. Calibration is also necessary in regular scale
maintenance due to normal mechanical wear-and-tear, changes in seasonaltemperature, humidity, air pressure, etc.
 The scale is equipped with gravity compensation, which allows it to be calibrated in
one location and then adjusted to match the gravity acceleration at another location
where it will be used. But don’t worry about this, as far as you calibrate the scaleusing a calibration weight and use it at same place.
 The scale must perform "warm up" for at least 30 minutes before starting calibration.

8-1. Calibration Procedure Using a Weight The scale should be powered on at least one-half hour to warm it up before startingthe calibration procedure.
1. Remove the calibration switch cover, and press the calibration (CAL) switch.

10. ACAI FUNCTION
Automatic Counting Accuracy Improvement

COUNT

The ACAITM (Automatic Counting Accuracy
Improvement) function recalculates the unit
weight as more pieces are added to improvethe count accuracy.

WEIGHT

UNIT WEIGHTACAIACAI Notes

 You must do the ACAI procedure just after you set the unit weight. The samples
must still be on the weighing pan.
 Do not take the samples off until the end of the ACAI procedure.
 You don’t have to count out the pieces when you add, just stay within the ACAI
range.
 Continue the ACAI procedure to reach the largest amount that you will be counting.
 If you want the most precise counting results for every different batch of the same
items, use ACAI every time you start counting the next batch.

 The ACAI function is initially set to manual operation when the unit weight is set
digitally by the keyboard, by ID memory or using computer via the serial interface.
This can be set to the automatic mode. The ACAI mode when the unit weight isentered by ID or digital input is controlled by F-Function f-02-02. It is initially set at“0”, ACAI manual operation mode. Set to “1” for automatic operation mode.

10-2. ACAI Automatic Operation

11-1. AWA

11. AWA FUNCTION
Audible Weighing Assist

The AWA (Audible Weighing Assist) function will assist you to count a certain amountof pieces by listening to the buzzer sound. The buzzer sound changes its interval as
the pieces getting close to, and stops at, the target count.
There are three modes of operation. These can be selected by the
key.
♫ Off mode: AWA function disabled.
♫ Target mode: To set the number of pieces that you will count.
♫ Interval mode: To set the number of pieces as an interval count. For example,
when 20 pieces is set as an interval count, the target count will be 20, 40, 60,… pieces.
 The buzzer starts to beep at the “target count – 9” pieces. As you add pieces andthe count is getting close to the target, the buzzer changes its interval of beeps,
shorter and shorter. Finally it stops at the target count.
 The buzzer will beep again for “target count + 1, 2, 3 or 4” pieces.
 The minimum number of pieces to set is 10.
 The number of pieces is set to less than 50 in the interval mode, the buzzer will start
to beep at the “target count – 5” pieces.
 You cannot set a minus target or interval count. But the AWA function works fornegative pieces, too.
 The AWA function should be disabled when the comparator buzzer is used.

11-2. To Enable/Disable the AWA Function

Press thekey, then the display will show one of the three modes of operation to
set. The display moves among these setting modes cyclically by pressing thekey
to select one of them.
 Press the RESET key in the setting modes, the scale returns to normal withoutchanging the AWA function setting and the unit weight you are using.

Off Mode Setting

COUNT

1. The count display shows “off” blinking.
2. When you do not use the AWA function, press

13-7. Using UFC (Universal Flex Coms) Function
 The UFC function allows you to format the print out (UFC format).
 The scale can store the UFC format as text data. It will include parameters to
replace with the count data, weight data and so on.
 The maximum number of text data is 384 characters.
 The terminator for the “PF” command is "CR" or "CRLF".
 Using the “PF” command, the text data has to be sent to the scale from thecomputer in advance. Then, connect the scale with the printer.
 When the PRINT key is pressed or by auto-print mode A/B, the scale will send thestored text data with the parameters replaced by the original data.

 ASCII text string
A text string is described in single quote marks as ‘Data’.
The single quote itself is written as ’’(2 single quotes).
Example:Text ‘ABC’ is described as ‘’’ABC’’’.
 The ASCII hexadecimal code
The ASCII hexadecimal codes are written in the form “#" + 2 hexadecimal digits.
This will mainly be used to send control codes that can’t be described as a text string.
Example:#04“EOT” of ASCII code
 Repeat data
The control codes $SP, $CR and $LF can be used with “ plus a 1 or 2 digit
number”. That code will be repeated the number of times designated.
Example:$LF 9
Repeat “$LF” 9 times.
$SP 12
Use 12 “Spaces”.
 Link mark “&”If you will send more than 2 lines of data, attach “&” to the end of the first line. Then,the scale considers the data to be continued.

 A “Space” or “,” will be used to separate these data. You can skip them, but
you cannot skip “,” after “PF”. You must start with “PF,”.
