1. Special 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. High-speed Conversion Method
24bit High-speed A/D converter that can detect the sensor’s input signal at a rate of
1000times per second is used. For analog output, 16bit D/A converter with 1000times per
second is used so that there is almost no devuatuib betweeb display value and output value.
1-2. Calibration Method
2 types of calibration systems are adopted. Calibration by actual load (standard weight) and
calibration by rated output of sensor (mV/V).
1-3. Hold and Peak Hold
You can choose Analog peak hold (High-speed) or Digital preak hold (Low-speed) as per
your need.
1-4. Comparison Output
You can do set-up the maxium and lower limit value by the keys on the front panel and output
contact point signal of the rear panel.
1-5. 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.
1-6. Watch dog
This function is for automatic reset in case the system is stopped due to the external factors
such as noise.

3
1-7. Option
You can use RS232C, RS485 and 4 relay output as the optional specification.
1-8. Power
AC 220V 50/60Hz

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.

◀Attention▶
1. When wiring, please pull out the power plug. (Main power supply)
2. Please use the thick calbe for ground terminal ( ) so that you can avoid any trouble
due to the impulse voltage or surge. If possible, please keep it as an independent
ground.
(This must be used in the area with heavy noise. If the ground is made with other
device, it will be affected by noise.)
3. Please check the function of the terminal before you do the wiring so that you can
prevent any malfunction in advance.

operation method, please refer to the drawing below.
1) Peak Hold : To Hold the maxium value among the measured values.
Analog peak hold mode : It is a high-speed Peak hold. It is to hold and display the
maximum value of (+) direction.
Display peak hold mode : It is a low-sped Peak hold. It is to hold and display the
maximum value of (+) direction.
Absolute peak hold mode : It is a low-speed Peak hold. 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.

7-3. 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 (HI)
Measured Value ≥ Upper limit setup value ⇒ RY2 ON (LO)
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 ≥ RY4 setup value ⇒ RY4 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
Measured Value< RY4 setup value - Hysteresis value⇒ RY4OFF
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 ≤ RY4 setup value ⇒ RY4 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
Measured Value > RY4 setup value + Hysteresis value⇒ RY4 OFF
4) Low & 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 ≥ RY4 setup value ⇒ RY4 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
Measured Value < RY4 setup value - Hysteresis value ⇒ RY4 OFF
