Functions of Components

Expert 125, 250 and 400 Models

Wrench Housing

Incorporates all the electronics and digital display.

Wrench Handle

Houses the charger/data port connector for battery charging and serial port communications.

Wrench Head

Contains the angle reference arm potentiometer (EA-models) and ratchet head. The wrench head can be indexed 600 either side of the wrench body for ease of reading the display.

NOTE

Factory Calibration of models 125, 250 and 400 was conducted with the wrench head in the normal, non-indexed position. This position is recommended where high accuracy of angle values is required. If the wrench is to be used in the ±60o indexed position and angle accuracies equal to or better than ±10% are required, then recalibration of angle in the indexed position is recommended.

Torque accuracy remains unaffected by indexing the wrench head.
