TAKING A MEASUREMENT
TO TAKE A BELT RESONANT FREQUENCY MEASUREMENT:
1. Press “MEASURE”, to initiate measurement mode on the 350C Sonic Tension Meter.
2. Position microphone head <1cm from the center of the belt span. The small holes in the microphone head should be
directed towards the belt.
3. Tap or pluck the belt in the center of the belt span so that it oscillates up and down relative to its direction of travel.
4. The belt resonant frequency shall appear on the display.
Below diagram shows the user interface elements for taking a measurement.
FREQUENCY READING AREA:
FLASHING BARS = measurement mode
i.e. currently ‘listening’ for belt resonance
SOLID BARS = on standby
VALUE = most recent measured value, Hz.
MEASURE BUTTON:
Press once to start measurement.
The device will continue to listen
for a belt resonance until detected.
To exit measurement mode,
press “MEASURE”.
SIGNAL STRENGTH:
Shows the quality of the received
signal used to identify the belt
resonant frequency. All three bars are
filled when signal quality is highest.
Improve signal quality by following
“Tips on Using the Gates Belt
Frequency Meter”.
