§１．Summary
This unit is a high speed sampling, 2,000 times per second, digital indicator for exclusive use of
the strain gauge transducer that is most suitable for a system which needs high-speed control
such as filling object, pressure or torque.
Frequency characteristic of analog filter of this unit is selectable by 2 switches on rear panel.
Selectable 12 cut-off frequencies help to response various kind of input signal easily.
This unit has a main LED indicator to display the measured value and a sub LED indicator todisplay Tare Subtraction, Preset Tare, Integrated value, Hold level, it also can display thepercentage of the measurement level against output of maximum load as the bar graph or
numeric value. Also display a unit or the number which is converted.
This unit has 6 points of external comparator output as upper / lower limit judgement andwindow comparator judgement as LO/GO/HI. Also has 6 points of external command input
which are able to be allocated as various function .
As an option, This unit can be installed as 4～20mA current output, ±10V voltage output,
RS-232C/485 and BCD output. (specified at the time of order)
The power supplied voltage is AC100 to 240V or DC24V (specified at the time of order).

§２．Installation and connection method of the unit2-1) Installation environment of the unit
1) Operation temperature range of this unit is −10℃～+40℃.
Please install the unit where the place does not have direct sunlight and condensation.
2) The power supplied voltage is AC100～240V(as standard) or DC24V(as option).
Recommend to use a constant voltage transformer if AC power supply is not stable.
3) This unit can be installed to the panel. Please install by using attached metal fittings.
4) Terminal array are 7.62mm pitch crimped terminals. Wire to them using Crimp terminalfor M3 up to 6mm width. Please confirm the cable specification before wiring.
5) The shield of each cable should be grounded to one of this unit or each connected unit.
2-2) To obtain stable measurement
When a sensor of strain gauge (i.e., Load Cell, Pressure gauge) is amplified by an amplifier oris connected to an indicator, the value may fluctuate or may not be stable.
Control Unit
(PLC, etc.)

SensorIndicator, Amplifier(DLS-5037, etc.)( Fig. 1 )This is because of difference of an electric potential between a sensor part and an amplifier /indicator part. It is induced from electricity rounding of general commercial power supply(AC100V/AC200V).

( Fig. 2 )The most effective way to improve stability is to use a cable to connect an Earth terminal of anamplifier / indicator to a case or chassis of sensor, lik e Fig 2.
If it is difficult to find an Earth terminal of sensor side, loose bolt of metal case of sensor andconnect the cable. Please make the electric potential be same as possible.
In case that a sensor and amplifier / indicator have installed apart s eparately, stability improves
when an Earth terminal of indicator / amplifier and metal case of sensor connect to the nearest
earth of each. But if they are apart far from each other, it may not bring a good result due todifferent electric potential of the earth. However, in such a case, stability improves if connecting
a cable as Fig 2.

] let integrated
value to clear.
Repeat same procedure from 4 in case ofchanging target value.
Repeat same procedure from 5 in case ofsame target value.

Example) Measure load amount on cargo bed of truck while loading with a crane① Set maximum load of 10ton (10,000kg) as target value
target gap = -10,000kg② 1st load = 2,000kg
target gap = -8,000kg③ Press ＊ key or external command to add④ 2nd load = 3,000kg
target gap = -5,000kg⑤ Press ＊ key or external command to add⑥ 3nd load = 4,000kg
target gap = -1,000kg⑦ Press ＊ key or external command to add⑧ 4th load = 1,200kg
target gap = +200kg
Target gap exceeds +200kg. Change to more lightweight load.
Before addition operation, integrated value is not settled thus can be recalculated.
Change 4th load = 900kg
target gap = -100kg⑨ Press ＊ key or external command to add⑩ Finish measuring with margin 100kg remained
If target value is set to ‘0’, target gap equals the sum of integrated value and measured Net
value, which easily anticipate the value before addition operation.

§６．Calibration
As for calibration method, there are two kinds of calibra tion as [Equivalent Input Calibration]
which input the equivalent output voltage of the Load Cell by key operation (available only
EXC=5V), and as [Actual Load Calibration] which use a weight as an actual load. Calibration canbe done by either method but it will be operated by the last performed calibration value. It is
recommended to calibrate by actual load as much as possible .
To correct non-linearity of a sensor or Load Cell, This unit is able to calibrate five span points.
If it is not necessary, Set 0 in [⊏/ ⊏～] of Function Mode. After non-linearity
correction is done, span correction value is re -sorted ascending order.
6-1) Calibration Lock
There is a function of calibration lock for not to break a calibrat ed value by wrong operation. If
span calibration is going to be performed, it is displayed wit h [] and does not accept achange during CAL LOCK. But zero point calibration can be performed.
Calibration lock procedure as follows.

4～20mA current output (OP-1) / ±10V voltage output (OP-2)

After A/D converts the input signal from Load C ell to digital data, D/A converts it to analog
output again. By a scaling function, it can link a display value to 4mA or 0V of analog output, andcan link a display value to 20mA or 10V of analog output. In addition, it can fine -tune at 4mA,
20mA, 0V, +10V and −10V in order to regulate level error against input of instruments
connected to this unit. Analog output is isolated from internal circuit. By using Test Mode, it can
output 11 steps between 4～20mA or －10V～0～+10V.

RS-232C (OP-3) / RS-485 (OP-7)

In serial data interface of RS-232C or RS-485 conformity, it corresponds with two-way
communication by the Half Duplex system.
It is isolated from internal circuit.
RS-485 can allocate identification number of connected unit from L01 to L99. (Maximum
number of connectable unit is ten).
Writing ‘non’ as identification number doesn’t identify the unit , which result in one to one
communication. Interface of RS-485(OP-7) has internal termination resistance. If this unit isconnected at the terminal end, it should make short between ⑤ and ⑥ of RS-485 terminal.

§１０．Troubleshooting
If this unit does not work properly, please take the following measures . If the trouble still cannot
be solved, then please contact our company.
At query, please inform us the model name, product serial number, and conditions of this unit
as detailed as possible.
10-1) Basic check point
1) Please check if using a correct power supply. this unit is supplied with voltage AC100～240V
as standard or DC24V as option.
2) Please check that wires are connected to the terminal base properly.
10-2) Precautions at the time of calibration
1) Error occurs at the time of zero point calibration.
・In case of exceeding the setting range of zero point.
To perform zero point calibration, Load Cell output with no load should be in the range of‐2.8～+2.8mV/V
If using Load Cell which has rated output more than 3.3mV/V and its no load output
exceeds ±2.8mV/V, please contact our company.
2) Error occurs at the time of span calibration, or display value is not correct as set in spancalibration.
・In case of output voltage of Load Cell being large.
This unit cannot measure in a system that the sum of initial tare value and measured
value exceed 3.3mV/V.
If using Load Cell which has rated output more than 3.3mV/V, please contact ourcompany.
・In case of span calibration voltage is slight.
If span of Load Cell output with a load is lower than the setting value of span, calibration
is incorrect.
Make resolution rougher to set minimum scale higher, or use an appropriate Load Cell.
3) Fluctuation of measured value
・Inappropriate span setting value against resolution.
Since the input sensitivity of this unit is 0.5μV/digit, the maximum display resolution is
1/10,000 when input 1.0mV/V. Exceeding this resolution makes fluctuation obviously.
Set minimum scale higher to make fluctuation less to the degree not perceivable.
10-3) Countermeasures for unusual display
・Measured value is blinking (over load indication) when not overloaded.
A part of sensor cable might be broken or a sensor itself might be defective.
Please confirm the input voltage (mV/V) from a sensor in Test Mode.
10-4) Judgement whether this unit has malfunction
1) Please confirm whether a sensor excitation voltage is correct.
Disconnect a sensor from this unit and check the voltage by a tester between #1(+EXC)
and #4(-EXC) of terminal block. Please check whether it is stable at 5V±0.5V (EXC=5V).
If it is unstable, power circuit for a sensor in this unit is failure.
2) Short-circuit ( Jumper between No.5 (+SIG)～No.6 (-SIG) ) at terminal block.
Display input voltage (mV/V) in Test Mode. Then check if the input voltage is stablenearest to zero. If unstable, this unit is failure. If stable, please check a sensor side.
3) Check external input / output
Check external input / output in Test Mode .

MA4-00262-R2

10-5) Checking a sensor (Load Cell)
Good or bad rough judgement can be done by measuring input/output resistance andinsulation resistance because the Load Cell is structured by a bridge circuit. ( Please makesure to power OFF this unit first and disconnect Load Cell before checking resistance)
1) Fault judging method by resistance of Load Cell
Check bridge resistance of Load Cell by a tester and confirm whether input/output
resistance are correct2) Fault judging method by insulation resistance of Load Cell
Measure the insulation resistance between shield line and other with voltage less than
50V. If the insulation resistance shows more than 1000MΩ, insulation of Load Cell is no
problem.
