Measurement
UK
Press the "Measure" key and the green LED
will begin flashing. It will flash until a signal
is received by the sensor. Tap the belt span
F
to make the belt span vibrate. Hold the sensor
approximately 1 cm (0.4 inch) from the belt
or closer as long as the belt does not hit
the sensor. The green light will turn off after
a signal is received and remain off for about
I
1.5 seconds during processing. The measured
belt tension is then displayed, the meter beeps
three times and the green LED turns back on
and remains on until another signal is received.
E
If the belt tension or frequency cannot
be measured, the red LED will turn on.

The units of measured force can be switched
between kilograms, pounds and Newtons.
D
This can be accomplished as follows:
When the power is switched off, press the "0"
and "9" and "Power" key down at the same
time. Units can then be changed by pressing
PL
the "Select" key until the desired unit appears.
Press the "Power" key again to return the meter
to its normal operating mode.
R
Frequency display
F =
Press the Hz key to view the frequency
TJ measurement.
When the Hz key is pressed again,
the measured tension is re-displayed.
If the Hz key is pressed a third time, a double
indication is given in Newton and Hz.
Measurement errors
If the belt tension or frequency cannot be
measured the red LED will turn on. If an error
has been made in the measurement, "ERROR"
will be displayed. Continue to retry the
measurement until tension is displayed.
It is not necessary to press the "Measure" key
again. If the memory is not used, the tension
meter switches to "ERROR" after three
measurements. Switch the meter off and
on again to continue measuring.
If the double display is used (Newton – Hz), then
the unit for which a value cannot be displayed,
will be indicated with a dotted line.
Frequency range
A frequency filtering feature is available to focus
the meter frequency measurement response
to a narrower range. This can be useful in
improving the response of the meter, and
in filtering out potentially interfering
background noise.
The standard selected frequency range is
between 10–600 Hz. The frequency range can
be changed. Hold down the "0-RANGE" button
one second or longer. The frequency ranges
STANDARD (10-600 Hz) or HIGH (500-5000 Hz)
