Using the MULTITEST Toque Calbration System

Example:

When tool accuracy is 4% and MULTITEST Indicator /

Transducer System accuracy is 0.25%, readings should

be within ±4.25%.

9. Release the torque, CLEAR the indicator display, and

reapply torque for each of the remaining check points

recommended by the tool manufacturer. If no

recommendation is available, check at 20%, 40%, 60%,

80% and 100% of the tool full scale.

10. Repeat steps 4 through 9 in the counter clockwise

(CCW) direction.

Adjustable or Preset “Click” Wrenches and

Screwdrivers

Be sure the MULTITEST transducer is capable of handling the

intended torque to avoid damaging transducer. Always operate

the system with the power on.

Do not use this equipment with the power off.

Always turn on the indicator and loader so the

torque and load values are indicated on the display.

The safety relays only work when the power is on.

1. To program the MULTITEST Indicator refer to Chapter

3–Set Up and Programming. Use SET HIGH and SET

LOW limit alert, data STORE, display CLEAR, printer

SEND and STATistical analysis features.

2. Press UNIT to select the desired engineering unit of

measure as displayed on the LCD display. It is easiest

to match that of the tool under test.

3. Press MODE to select TRACK mode. The green TRACK

lamp lights.

4. Adjust the tool for maximum “click” setting. Install the

tool on the torque transducer-loader. Slowly apply torque

using the loader crank handle until the tool clicks or the

Indicator displays 100% of the full scale capacity for the

tool. Release the torque and repeat twice again to

exercise the tool and the transducer.

When applying torque by hand, make sure to hold the

drive end of the tool perfectly in line with the transducer

drive to minimize side loading errors.
