Using the MULTITEST Toque Calbration System

Measuring Torque and Angle

Although measuring torque and angle is not a torque testing

feature, transducers and the MULTITEST Indicator may be used

to monitor torque during fastener installation. The Indicator can

also be set up to monitor "turn-of-the-nut" or angle of rotation

using common bi-directional incremental rotary encoders for

critical fastener installations. Typically, a torque-angle algorithm

is used where the joint is clamped using a preload torque. The

fastener is then rotated a specific number of degrees regardless

of the torque necessary to turn it.

Torque Only

When using the instructions in this section refer to the Torque-

Angle Tutorial Quick Reference Card that accompanies this

manual.

1. For additional information on setting SET HIGH and LOW

limits alert, Data STORE, display CLEAR, printer SEND

and STATistical analysis features, refer to Chapter

3—Set Up and Programming.

2. Press UNIT to select the desired engineering unit of

measure as displayed on the LCD display.

3. Press MODE to select TRACK or PEAK HOLD mode.

4. Install the transducer between the fastener and the

wrench or tool.

5. Apply increasing torque until the audible tone indicates

that measured torque matches or exceeds the SET LOW

torque limit. If you match or exceed the SET HIGH

torque limit, the alert sounds a pulsating tone.
