Measurement Modes Peak, Mean Measurement modes are available on the TRC: To select the measuring mode required for testing, follow the settings below. Mean Mode Peak Mode Mean Peak Mean Peak Mode Mode Peak Mode The Peak value displayed on the TRC is measured at 1,000 times per second. (1000Hz) The Peak value is reset by pressing the Reset key or activating the Auto reset function (refer to 4.1.3 Auto Reset Setting).
Comparator Function • This function compares the High/Low limits and measured data (Mean Mode) or peak data (Peak Mode) or memory data. The result is displayed by Comparator LED indicators. • If both High and Low limits are set to 0, the Comparator function is deactivated. Refer to 4.2.2 Operation.
Measuring Torque Wrench – torque measurement To measure torque, insert the torque wrench square drive into the TRC socket attachment. Socket for torque wrench Torque wrench Electric Screwdrivers/Torque Driver - torque measurement To measure torque, insert the adapter into the attachment of the TRC as shown below.
The adapter is a consumable product. Replace the adapter when it is impossible to perform a repeatable measurement.
