2. Operation
2.1 Installation
Please fix the torque tester on the workbench. See Appendix A-2 Installation dimensions.
2.2 Adapter Selection
2.2.1 Square Drive Adapter
Basic Adapter: □1/2” (12.5mm) socket. accordance with the appropriate scale to provide □1/4 "(6.3) or □
3/8" (10) square drive adapter.
2.2.2 Spring Adapter
An adapter that checks the torque value preset on an electric driver and absorbs inertia created by high
speed rotation,giving nearly the same torque effect as an actual tap screw.

The torque gauge has a variety of measurement units, select the appropriate unit.
2.4.2 Select Test Mode
This series torque tester has 5 kinds of measurement test mode can choose. You can select it by press
under the measure interface, Or can change it in menus (See 3.2.3 Test Mode ).
Track: The real time measuring mode, under this mode, press the zero key the torque gauge will be cleared
(remove tare).
- 3 -

Peak: Peak readings will not change until a higher value is measured. Under this mode, press the zero
key the torque gauge will update the display immediately.
Preset:The tolerance limits can be set for GO/NG measurement also. If you set the alarm on and a valid limit,
The icon , , will be displayed for within limit, lower than lower limit or exceed upper limit.
First Peak: In this mode, the gauge can capture the first peak value of force, when the force value decreased
to reach the drop ratio. The drop ratio can be set in menus.
Auto Peak:In this mode, the peak capture will be updated in the time interval set in menus automatically
Auto First Peak:The first peak capture will be updated in the time interval set in menus automatically
2.5 Zeroing
Press to clear the torque gauge in track mode for removing the tare.
2.6 Storage/Print
Measured results can be stored in the torque gauge, so that you can review or print them later.
Under the measure interface, Press to save value measured, and the save icon will be displayed.

① Preset
In the Tolerance menu, program
upper and lower limit for GO/NG Measurement.
The upper limit value must be greater than the lower limit, and
both limit value cannot be greater than 110% of the rated
capacity.
② First Peak
With 5% increase or decrease in the drop ratio of the adjustment
amount setting.
③Auto Peak
The Peak time should be set(Fig.3-6)

window will pop up for further
confirmation.
3.4 System setting
3.4.1 Display Mode
There are two display modes:
Digital and Graphic.
3.4.2Power Off
The torque tester can turn the
power off automatically, some
time interval after no measuring
and no any operation. 5 minutes is default. You can change it for a longer or shorter
standby.
3.4.3 Back light
The torque tester can turn off backlight, some time interval after no measuring and no

3.4.6 Key Set ting
The key is a multifunction key.
It can be set as "store the current display value(Storage)" or "print the recent data
(Print)"."Storage" is default.
3.4.7Default Setting
When the artificial error, and do
not know how to restore, the
gauge can be restored to factory
settings. it will lose that some
information set by customs.
Restoring to Default Setting, the
password must be enter and a
prompt must be confirmed.

4. Communication Ports
There are two kinds of port for recharging and communicating with
PC and the other equipment.
4.1 USB/Recharge
Use this port, you
can connect the
gauge to the
computer for
transform data to PC in accordance with
USB2.0.
Or recharging with connecting the recharger.

5. Calibration
Because of the sensor material performance or the influence of
external factors, there may be errors in a certain range after a
period of time use. Should send the torque gauge to a
specialized testing organization for calibration.
If you have some standard force weights or the other
standard load and some test stand, you may calibrate it also.
① Mount the torque gauge.
② Remove the tare by use of the key .
③ Enter Calibration interface, as Fig 5-1. (Password: 1 2
3)
④Load a standard force.Now the value in standard
input area is just equal to the current measured value.Wait a
moment for the force stability.
⑤ Press and to input the standard force value.
⑥ Press to enter the next calibration. Press can interrupt the calibration.
NOTE:
❶Set the unit of force to the unit used in calibration previously (as shown in 3.2.1 Unit)
❷Ensure that the tare weight of attachment has been remove before calibration.
❸You can do any point or points calibration from 1 to 5 point, we recommend 5 points calibration.
