■ Operation
First check the battery level!
Turn the power switch on. If the charge is inadequate, the message "LOBAT" will be displayed. In that
case, recharge the battery for about 3 hours. Never recharge for more than 8 hours.
1. Bolt the detector unit to the work bench.
2. Set unit converter switch to the desired measurement unit.
3. Set mode switch to the desired measurement mode and use
the zero adjusting knob to adjust the displayed value to zero.
4. Conducting measurement
• Track measurement:
Set mode switch to "Track." Changing torque values will
be displayed according to the load to the detector unit.
Display returns to zero when the load is removed.
• Peak measurement:
When peak measurement is desired, set the Mode
Switch at PEAK. The peak value is held for more than 5
seconds when more than 15 digits signals are inputted.
It can be cancelled by pushing the reset button.
• First peak measurement:
Set mode switch "First peak." Use for measuring torque wrenches. Measures first peak values
and gives an audible signal when first peak is reached.
* Use size 9.5 x 9.5 or 12.7 x 12.7 square sockets (commercially available), or make a socket
adaptor for other sizes.
Measurement of impact drivers
(1) Attach a 9.5 x 9.5 or 12.7 x 12.7 square socket adapter to the detector unit socket.
(2) Fit the driver into the adaptor and start the motor.
(3) The peak load value will be displayed. Read off this value and push the reset button to cancel
the value.
(4) Repeat the above process as necessary.
Torque wrench measurement
(1) Set mode switch to "FP."
(2) Attach a 9.5 x 9.5 or 12.7 x 12.7 square socket adapter to the detector unit socket.
(3) Fit the wrench into the adaptor and start the motor.
(4) You will hear a "click" when the first peak has been measured. The display freezes on this
value. It does not change with changing load to the detector unit.
(5) Read off this value, then push the reset button to cancel it.
(6) Repeat the above process as necessary.
