6 SETTING UP THE GAUGE

6.1 TRANSDUCER - ZEROING
Setting the zero point of the gauge is important for the same reason that setting the zero on a mechanical
micrometer is important. If the zero point of the gauge is not set correctly, all of the measurements the gauge
makes will be in error by some fixed number. When the zero point of the gauge is set, this fixed error value
is measured and automatically corrected for in all subsequent measurements.
Though the gauge will remember the last zero point, it is generally a good idea to set the zero whenever the
gauge is switched on, as well as any time a different transducer is used. This will ensure that the zero point
of the instrument is always correct. The zero probe routine must be done prior to calibration.
To set the zero point:
1. Plug the transducer into the gauge ensuring that the connectors are fully engaged. Check that the
wearface of the transducer is clean and free of any debris.
2. Press ON/OFF key to switch on the gauge.
3. The battery compartment cover on the top end of the gauge acts as a metal 'probe-disc'. Apply a
single droplet of ultrasonic couplant to the face of this disc.
