1. Special Features
We are grateful to you for picking up our product. If you experience problems while
using it, you may refer to the user manual or contact the Technical Support Department
of the company.
This product is an indicator which displays Torque and RPM in digital mode and it
has the following features.

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 Peak hold or Sample hold 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.

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.

Digital or Display Hold as per your purpose of use (Hi or Low Speed)
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 a high-speed Peak hold. It is to hold and display the
maximum value of (+) direction.
Absolute peak hold mode : It is to hold and display the 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 ⇒CH1 : RY1 ON, CH2 : RY3 ON
Measured Value ≥Upper limit setup value ⇒CH1 : RY2 ON, CH2 : RY4 ON
2) High limit mode : Measured Value ≥RY1 setup value ⇒CH1 : RY1 ON, CH2 : RY3 ON
Measured Value ≥RY2 setup value ⇒CH1 : RY2 ON, CH2 : RY4 ON
Measured Value < RY1 setup value – Hysteresis value⇒CH1:RY1 OFF, CH2:RY3 OFF
Measured Value < RY2 setup value - Hysteresis value⇒CH1:RY2 OFF, CH2:RY4 OFF
3) Low limit mode : Measured Value ≤RY1 setup value ⇒CH1 : RY1 ON, CH2 : RY3 ON
Measured Value ≤RY2 setup value ⇒CH1 : RY2 ON, CH2 : RY4 ON
Measured Value > RY1 setup value + Hysteresis value⇒CH1:RY1 OFF, CH2:RY3 OFF
Measured Value > RY2 setup value + Hysteresis value⇒CH1:RY2 OFF, CH2:RY4 OFF
