CDI Torque MULTITEST Motorized Loader - Manual (Page 47)

4-3
Using the Multitest Toque Calbration System
Example:
When tool accuracy is 4% and 2000-810-01 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.
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. 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.
