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 2000-800-02 Loader power on.
WARNING
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.
1. To program the 2000-810-01 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 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.
