Using the Multitest Toque Calbration System
Measuring Torque and Angle
Although measuring torque and angle is not a torque testing
feature, transducers and the 2000-810-01 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.
