1. Features
We thank you for using our product. Please refer to this manual or contact our office if
you find any problems during using our product.
This product is an indicator that emplifies the micro voltage signals from each sensor
and display in digital. It is mainly used to measure physical quantities of the items using
strain guage such as loadcell, pressure sensor, displacement sensor and torque sensor.
This product has the following special features.
1-1. Calibration Method
2 types of calibration systems are adopted. Calibration by actual load (standard
weight) and calibration by rated output of sensor (mV/V).
1-2. Hold 및Peak Hold
You can choose peak hold and sample hold as per your need.
1-3. Comparison Output
You can do set-up the maxium and lower limit value by the keys on the front panel
and print with contact point signal of the rear panel.
1-4. Data Back-up
All the set-up values will be memorized on the flash memory so the inputted data can
be saved and no need to do the re-setting even in case of the interruption of the
electric power or power disconnection.
1-5. Watch dog
This function is for automatic reset in case the system is stopped due to the external
factors such as noise.

2. Attention
For the efficient and safe use, please carefully read and be fully aware of the following
details before using this product.
It is strictly forbidden to use this product for any other purpose of use or to attempt to
make any alteration on this product.
2-1. Attention for installation
•Please keep it out of wet places.
•Do not set it up near vibration & impulse, high temperature and humidity.
Keep it out of the direct rays of the sun. Set it up where there is less dust, and Keep it
out of direct air including salt and ion.
•Do not use when there is inflammable gas or heavy machinery, and smog.
•Ground earth-terminal ( ).
•Make wire separately from power system wiring and noise wiring.
•Make sure the use of 4 line sealed cable as a sensor cable.
Too long cable leads to measurement error due to wiring resistance (around
10meters).
2-2. Attention for use
During calibration, Do not input free-load state and real-weight load until it becomes
stable. Pressing Enter Key in unstable condition leads to calibration error.
Do not press any Key in use at one's discretion. Please refer to 7. Setting-up mode
for the function and method of Key.

7. Components & Function
7-1. How to use Hold mode
Hold mode is largely divided into Peak Hold and Sample Hold. Please select Peak or
Sample. To input Hold, you can use Hold key on the front panel or external input. For
the operation method, please refer to the drawing below.
1) Peak Hold : To Hold the maxium value among the measured values.
Peak hold mode : It is to hold and display the maximum value of (+) direction.
Absolute peak hold mode : It is to hold and display the maximum value of the
absolute value (+/-).
2) Sample hold : It is to hold and display the value at the time of Hold signal input
among the measured values.

7-2. How to use comparison ouput function
For comparison output function, there are 3 different modes such as Decision, High
limit, Low limit. It displays through the relay of rear panel comparing each setup value.
On High limit and Low limit mode, Hysteresis can be used.
To set up upper limit (High) and lower limit(Low), please use the key on the front panel.
1) Decision mode : Measured Value ≤Lower limit setup value ⇒RY1 ON (LO)
Measured Value ≥Upper limit setup value ⇒RY2 ON (HI)
Lower limit setup value < Measured value < Upper limit setup value ⇒RY3 ON(OK)
2) High limit mode : Measured Value ≥RY1 setup value ⇒RY1 ON
Measured Value ≥RY2 setup value ⇒RY2 ON
Measured Value ≥RY3 setup value ⇒RY3 ON
Measured Value < RY1 setup value –Hysteresis value⇒RY1 OFF
Measured Value < RY2 setup value - Hysteresis value⇒RY2 OFF
Measured Value < RY3 setup value –Hysteresis value⇒RY3 OFF
3) Low limit mode : Measured Value ≤RY1 setup value ⇒RY1 ON
Measured Value ≤RY2 setup value ⇒RY2 ON
Measured Value ≤RY3 setup value ⇒RY3 ON
Measured Value > RY1 setup value + Hysteresis value⇒RY1 OFF
Measured Value > RY2 setup value + Hysteresis value⇒RY2 OFF
Measured Value > RY3 setup value + Hysteresis value⇒RY3 OFF
