1. INTRODUCTION
Thank you for purchasing the AD-4530 Digital Indicator.
This manual describes how the AD-4530 works and how to get the most out of it interms of performance. Please read this manual completely before using the AD-4530.

1.1. Features
The AD-4530 has the following features.
Calibration without an actual load (Digital span mode)
Keying in the sensor’s rated output voltage (mV/V) allows calibration to be performed
without using an actual load.
Digital filter
The range for selecting the cutoff frequency is none (no function) or 0.1Hz to 2.5Hz.
Digital zero (DZ, zero adjustment)
The digital zero function sets the measured value to zero. When measuring a load, it
can be used as the tare, etc.
The zero value is maintained in non-volatile memory (EEPROM). Therefore, whenturning the power off then on (or power loss), this zero value is still available. Memory
backup of 10,000,000 or more times is available.
Zero tracking function
The zero tracking function is used to set the corrected zero automatically by sensing
the zero point drift.
Hold function
Sample, peak, bottom and bipolar peak values can be held using the hold mode.
Comparison function
Comparison results (HI, OK and LO) are output as display data and also as contact
signals.
Chattering of the output can be prevented by setting the hysteresis.
Various data output terminals
Available options are comparator output, serial interface (RS-232C/RS-485), analog
voltage output (DAV) and analog current output (DAI).

2. BEFORE USE
The digital indicator is a precision instrument. Unpack the digital indicator carefully andconfirm that all items are present.

2.1. Precautions Before Use
Avoid water and moisture.
Avoid vibration, shock, extremely high temperature and humidity, direct sunlight, dust,
and air containing salt or sulfurous gases.
Avoid places where inflammable gases or vapors are present.
The operating temperature is -10°C to +40°C.
A 100 VAC to 240 VAC power source is required. Use a stable power supply free fromsudden dropout or noise as they can cause malfunctions. Avoid sharing the power line.
Keep cables away from power cables and other sources of electrical noise.
Connect only a non-inductive load of 10 kΩ or more to the analog voltage output
terminals.
Connect only a non-inductive load of 510 Ω or less to the analog current output
terminals.
When connecting long cables to the sensors, keep the cables away from power
cables and other sources of electrical noise.
Do not connect the AD-4530 to the power supply before installation is completed. The
AD-4530 has no switch to disconnect the power supply.
Use shielded load cell cables.
Do not connect too many sensors. Otherwise, instrument damage may occur.

2.2. Precautions During Use
The AD-4530 is a precision instrument that measures the microvolt output fromsensors. Prevent noise sources such as power lines, radios, electric welders or
motors from affecting the instrument.
Do not try to modify the AD-4530.
In all hold modes, the hold data is saved digitally, so there is no drooping of the value
displayed on the display panel or the analog output. Note that the hold function isdisabled when the AD-4530 is disconnected from the power supply.

4Disconnect from the power supply before removing the cover.
When removing the cover, make sure that the power is off.

Do not touch the instrument immediately after it is disconnected from the power
supply.
To avoid electrical shock, do not touch the internal part of the instrument
within ten seconds after switching the power off.

Be sure to fasten all the screws completely.
Loose screws may come off during operation and a short circuit may occur or
measurement errors may occur due to noise.

9. DIGITAL ZERO (DZ)
The digital zero function sets the measured value to zero. When measuring a load, it
can be used as the tare, etc.
While using this function, the DZ LED turns on.

9.1. Operating by key
When thekey is pressed, the display is set to zero, and the DZ function is turned on.

If you want to turn the DZ function off, press the

+

keys.

* The operating procedure depends on the setting of (Cf11).
Press the+keys or press and hold the

key for more than 1 second,turn on the DZ function.
When it is turned on, the display is set to zero.

9.2. Operating by I/O input
Whether the DZ function is ON or OFF depends on the operation of the zero terminal of
the I/O input.
When the zero terminal is on (connected to the Com terminal), the DZ function is turnedon and the display is set to zero.
You can disable the digital zero off in the function mode (Cf12).

9.3. Zero tracking
Using the zero tracking function, the AD-4530 updates the zero point automatically bysensing the zero point movement.
Zero tracking functions only when digital zero is turned on. Set the zero tracking time
(Cf08) and zero tracking width (Cf09) by setting the function.
* When the zero point is over the zero correction range, zero tracking is not performed.
* When refreshing the zero point using the zero tracking function, backup to non-volatilememory will not be performed.

Measurement is based on the zero point of the calibration.
Use with the measurement of an absolute value such as force measurement.
1: Perform digital zero again
Measurement is based on the zero point when the power is turned on.
Use with weight measurement etc.
2: Use the state when the power was turned off
Measurement is based on the DZ.
Use with measurements that require a long time such as a hopper scale.
It is a useful function in case of a power loss.

9.5. Backup of DZ

The DZ value is maintained in non-volatile memory (EEPROM).
Writing up to 10,000,000 times is available, so keep track of use frequency.
If the available DZ memory is 10% or less, the LED of the digital zero DZ blinks.
With the setting (Cf10=2), the backup memory is refreshed only when refreshed by key
operation or command.
(When refreshing the zero point using the zero tracking function, the backup memory is
not refreshed.)2910. HOLD FUNCTION
The AD-4530 has four hold modes: sample hold, peak hold, bottom hold and bipolar
peak hold. A hold mode can be selected in the function mode (f003).

10.1. Basic function
Start the hold function by pressing thekey, setting the hold terminal of theexternal input to on, or a serial communication command.

10.1.1. Operation by using the

key

Press thekey. The hold function starts and the AD-4530 holds the displayed
value.
While the display is in the hold mode, pressing the
key again cancels the holdfunction, and the AD-4530 displays the measured value.

10.1.2. Operation using the external input hold terminal
When the external hold input terminal is turned on (contact input), the hold function
starts.
To hold the displayed value at this time, keep the external input hold terminal in the onstate.
To cancel the display hold, set the external input hold terminal to the off state.

10.1.3. Operation using a serial communication command
The hold function is started by the hold on command “HCRLF” of the serial
communication and is canceled by the hold off command “CCRLF”.

10.2. Hold indicator
The AD-4530 displays that it is in the hold state by turning the

HOLD

LED on.

10.3. Priority when inputting hold
When inputting a hold, the external input hold terminal has a higher priority than any
other operation.

10.4. Over value during holdIf the value is over during the hold, the display is blank.
Ensure that a function with non-displayed data, such as the comparator or output, isprocessed based on the hold data.

12. COMPARATOR FUNCTION
The comparator function compares the measured value against the set values, and theresults are displayed by the LEDs. If the relay option is installed, it outputs thecomparison results (HI, OK or LO) from the rear panel relay output terminals.

12.1. Detailed description of the comparator mode
The relation between the comparison outputs and the upper and lower limit setting
values is as shown below:
Comparison result

Comparison condition

HI

Upper limit < Measured value

OK

Lower limit  Measured value  Upper limit

LO

Measured value < Lower limit* HI is output with a positive over limit, LO is output with a negative over limit.
Upper limit and lower limit values can be negative.
For example, if the upper limit value is -1000 and the lower limit value is -2000, HI is
output for the measured value of -500 and LO is output for the measured value of -2500.
Make sure that the upper limit value is greater than the lower limit value.

12.2. Setting the upper and lower limit value
Set the upper limit value (f101) and lower limit value (f102) of the function using thefollowing procedure. In the measurement mode, press theor
key to enter
the setting mode for the upper or lower limit value.
In the setting mode for the upper or lower limit value, the AD-4530 blinks the HI or LO
LED. (The relay output is not affected.)
The setting value is displayed. Set the value by operating the key.

Measurement mode

Shift the blinking digit to the value to be changed.
Change the value of the blinking digit.

HI

OK

LO

Change the polarity.
Store the setting, and return to the measurement mode.
Cancel the setting, and return to the measurement mode.
Measurement mode34

* If a key is not pressed within 20 seconds in the upper or lower limit setting mode, theAD-4530 will cancel the setting, and return to the measurement mode.
* The decimal point blinks to indicate that a number is being displayed, not a measured
value.

12.4. Hysteresis
A hysteresis width and time is provided for the output relay on/off timing to prevent theoutput terminals from chattering.
When the measured value exceeds the set value, the relay is turned on. If themeasured value falls below the set value and it is further reduced by the hysteresis
width, or if the hysteresis time has elapsed, the relay is turned off.
The hysteresis mode, time and width can be set in the function modes (f105 to f107).

35

12.4.1. Hysteresis upward 2-level judgment (f105=1)
Relation between HI and OK
When the measured value exceeds the set upper limit value, HI is output
immediately. Even if the measured value falls below the upper limit value, OK is not
output immediately. OK will be output when the measured value falls below thehysteresis width, or when the hysteresis time has been exceeded.
Relation between LO and OK
When the measured value exceeds the set lower limit value, OK is output
immediately.
Even if the measured value falls below the lower limit value, LO is not output
immediately. LO will be output when the measured value falls below the hysteresis
width, or when the hysteresis time has been exceeded.
