BELT TENSION MEASUREMENT WITH FREQUENCY METER
Refer to Figure 6-9. Follow instructions as follows:
A. Turn on the meter.
B. Hold the meter so that the probe is >10mm (3/8”)
away from the belt being tested. Do not touch the
belt with tester probe.
C. Pluck a single belt at the midpoint between the
motor and compressor unit pulleys. Try not to
disturb any adjacent belts, as this will give a false
reading.As the probe detects a vibration, the
meter will display the frequency. Record data.
D. Rotate the motor pulley through at least one
complete revolution and measure the belts
again, recording the results.
E. Repeat D for a total of 3 measurements.
F. Average the three measurements to obtain the
true belt tension.
G. Repeat for remaining belts.
H. Compare the resuls to the belt tension specifica-
tion in Table 6-1 and adjust if necessary.
