For most applications the Off Block Zero will be sufficient, however if it is found the gauge linearity
is off and extreme accuracy is required an On Block Zero should be conducted followed by an Off
Block Zero. This will adjust and eliminate any error.
These options may be accessed from MENU/PRB.
8.4 OFF BLOCK ZERO (AUTOMATIC PROBE ZERO)
1. When the ZERO PROBE screen is displayed, remove all couplant from the face of the
transducer and check that the wearface of the transducer is clean and free of any debris.
2. Press OK (or ESC to cancel).
When the automatic probe zero is completed the measurement screen is displayed.
Your gauge should now be calibrated.
8.5 ON BLOCK ZERO (MANUAL PROBE ZERO)
When this zero probe option is selected a warning screen is displayed informing you that you must
zero the probe before taking measurements.
1. Press MEAS to display the measurement screen.
2. Remove all couplant from the face of the transducer and check that the wearface is clean and
free of any debris.
3. Apply a drop of couplant on the transducer and place the
transducer as shown in diagram.
Note: Disregard the value displayed; it is not important. What is
important is accurately performing these steps to ensure
reliability of the zero calculation.
4. Press MENU, scroll to the PRB menu, scroll to the ZERO
PROBE function and then press ENTER.
The ZERO PROBE screen is displayed.
5. UP and DOWN toggle coating on/off.

Your gauge should now be calibrated.
8.6 TRANSDUCER - ZEROING FOR COATING ONLY MEASUREMENTS
Your gauge features an additional zero coating feature for use when measuring coatings to a high
accuracy is required
Note: For this procedure, a coating transducer must be fitted to the gauge.
