Using the MULTITEST Toque Calbration System

Dial and Bending Beam Torque Wrenches and

Screwdrivers

Be sure the MULTITEST transducer is capable of handling the

intended torque to avoid damaging the transducer. Always

operate the system with the 2000-600-02 Loader 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 2000-610-02 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. Install the tool onto the torque transducer-loader. Slowly

apply clockwise (CW) torque using the Loader crank

handle until the indicator displays the full scale torque 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.

5. Remove tool from the transducer-loader and wait

approximately 30 seconds then press ZERO TARE. Set

the dial indicator on the tool to zero, if possible.

6. Press MODE to select PEAK HOLD mode.

— The red PEAK HOLD lamp lights.

7. Reinstall the tool and apply CW torque to the first check

point or calibration point recommended by the

manufacturer. If the point is not specified, use the

desired working torque or about 70% of full scale.

8. Read the tool display. The percentage difference

between the indicator and tool readings should not be

greater than the sum of their respective accuracies.
