Using the MULTITEST Toque Calbration System

Use the following procedure to make force measurements.

1. To program the MULTITEST Indicator, refer to Chapter

3—Set Up and Programming in this manual. Use SET

HIGH and SET LOW limit alert, data STORE, display

CLEAR, printer SEND and STATistical analysis features.

2. Install the compression or tension fixture according to the

manufacturer’s instructions.

3. Press SELECT to select FORCE measurement.

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

lamp lights.

5. Press UNIT to select the desired engineering unit of

measure as displayed on the LCD display. It is easiest

to match that of the gauge being tested.

6. Apply load by turning the loader handle CW for tension

or CCW for compression. This may be reversed

depending on the fixture.

7. Release and reapply load twice again to exercise the

transducer and gauge.

8. With the load released, wait approximately 30 seconds

then press ZERO TARE.

9. Apply load according to one of the following:

• The check points recommended by the gauge

manufacturer, if specified, or

• The desired working force, or

• Approximately 70% of its full scale capacity.

Note or adjust the gauge reading to match that of the

MULTITEST LED display.

Displaying Statistical Analysis

The MULTITEST Indicator accumulates torque/force

measurements in a data list. The list is created with each

AUTO or MANUAL data store entry. Statistical analysis is

calculated on the list, and if SET HIGH and SET LOW limits are

established, draws a simple histogram of the results. These

features are very useful in statistical process control (SPC)

management. Statistical analysis can be previewed on the LCD

display or sent directly to a printer/computer port. For

additional information on setting up printer or PC ports, refer to

Chapter 3—Set Up and Programming in this manual.
