Changing Tolerance Settings:
1. The default setting is +/- 2% of pre-set torque. The operator can adjust the
the setting from 1 - 10% or turn it off.
2. With the wrench ON, hold the power button and press the “” key.
Keep pressing the “” key until you show the desired value.
3. The tolerance setting provides a visual and sound signal if the torque
Passed or Failed.
- If the torque is under the pre-set torque & tolerance setting - Yellow light
- If the torque is within the pre-set torque & tolerance setting - Green light
- If the torque is over the pre-set torque & tolerance setting - Red light
Applying Torque:
1. Tighten nut or bolt by applying a steady even pull using built in ratchet as
necessary. Wrench should be kept at 90 degrees to axis of bolt during
tightening.
2. When pre-set torque is reached, there are 3 ways to determine what torque
is being applied:
- Look directly at the LCD.
- Pre-set torque and look for the lights.
- Pre-set torque and listen for the buzzer.
3. Once pre-set torque is achieved, do not apply any more torque or you will
over tighten it.
LCD Contrast:
1. The operator can change the LCD contrast (viewing angle) by first pressing
and holding the Units button and then press the “” button. This is
useful when the temperature is very cold or very hot.
Notes:
The contrast changes very slowly, so be patient.
