2. Overview

GE-50576-A Acoustic Belt Tension Tester enables

belt tension measurement with no direct contact.

GE-50576-A is used to measure the belt tension of

engine accessory belt systems and Electronic

Power Steering (EPS) steering racks.

When the microphone is held close to the belt,

belt vibration is captured by the microphone when

the belt is plucked, and the frequency is displayed.

For more detailed procedures, please consult

published service information for the vehicle or

component being serviced.

7. Noise Cancelation

To reduce the effects of background noise, the

frequency range specification of the belt being

measured must be known.

Please refer to published service information for

the vehicle or component being serviced.

If possible, make the measurements in a quiet

area.

If background noise causes interference, touch

the set-up button and choose the Min/Max

setting menu

Adjust the min/max range as follows;

Min : Service information specification -

100Hz

Max : Service information specification

+100Hz

noise, and adjust threshold again to a tighter

range if background noise continues to be an

issue.

Min : Service information specification –

50Hz

Max : Service information specification

+50Hz
