1. Press ON/OFF key to turn power ON. The software version number appears,
followed by Measurement Units frequ. [Hz]) or tens. [N] and menu = enter.
2. Press ENTER and then DOWN ONCE, until display reads
sprachwahl (language), etc. If correct, exit the program by pressing
the ON/OFF key. If not, proceed.
3. Press ENTER . Display will show current language selection (flashing).

1. Press ON/OFF key to turn power ON. Display will show: V 8.0 and then
frequ. [Hz] or tens. [N]), depending on last setting, and menu = enter.
If setting is CORRECT, no further action is required. If INCORRECT,
proceed:
2. Press ENTER . Display reads display Hz/N/lbf.
3. Press ENTER . Flashing display now reads,
display in Hz or display Tension (N or lb/f ).
4. Press DOWN . Display will now start flashing, showing the
other units (Hz or N/lbf).
5. Press ENTER to accept the flashing units of measurement
(Hz or N/lbf). Display now shows display Hz/N/lbf.
6. Press ON/OFF key to turn power off.
5.3 Setting The Engineering Units (International or U.S.)

8.0 TROUBLESHOOTING
Measurement deviations of up to ± 10% for several measurements taken on the same
drive belt are, as a rule, not caused by a measurement error or fault in the unit. In most
cases, measurement deviations are due to the mechanical tolerances of the drive sys-
tems. If no measurement results are displayed despite careful preparations, this may
be due to one of the following two reasons:
1. The drive belt vibrates below the minimum measurement limit of 10 Hz.
Remedy
Tighten the belt or, if the Free Span length is very long and open, support
the belt in order to shorten the length. Enter the shorter Free Span belt
length (L) before repeating measurement.
2. Either no or low measuring values are displayed despite the drive belt
being correctly tensioned.
Remedy
It may be that the light from the measuring probe is not sufficiently
reflected. To improve reflection, affix a piece of light-colored reflective tape
to the belt or slightly moisten the belt at the measuring point.
