6.5 Ending Measurement Process
The strap retraction speed decreases about 3 to 5 cm before the end of the measuring run.
The strap grip is slowly drawn into the device, where it triggers a limit switch. The device stops
automatically.
►
The measuring run can be stopped before it is finished by pressing the “Stop” button; the
results of the measuring run are then invalid.

6.6 Querying Measurement Result
The result of the respective measuring run appears immediately on the display.
►
Press the “Bandauszug” button for additional measuring runs.
6.7 Evaluating Measuring Run
Evaluation and display take place after the set point speed has been achieved over a measur-
ing distance of 50 cm.
Z
The current sliding friction coefficients of the most recent
successful measuring runs are displayed.
Z
After five measuring runs have occurred, the measured
values of the last three measuring runs are averaged
and the value displayed in the last line. (If one of the
last three measuring runs was invalid, no average is
calculated and the entire measurement has to be re-
peated.)
Data and the measured values can be transmitted to a PC via RS-232/USB.
TIPS AND RECOMMENDATIONS
The special evaluation software GMG-VD is recommended for further processing
of the measurement results. It evaluates the data, archives it and creates logs!
TIPS AND RECOMMENDATIONS
On slightly inclined surfaces, perform two measurements with 5 measurement
runs each in opposite directions and calculate the mean value from both
measured values!
