8 SETTING UP THE THICKNESS GAUGE
8.1 AUTOMATIC TRANSDUCER IDENTIFICATION
If using a coating thickness transducer, the gauge will ask you to
confirm the transducer type.
1. Press OK to use the identified transducer.
Note: Always select OK to use the identified transducer type.
2. Ensure that the wearface is clean and free of any couplant or
debris then press OK to perform a probe zero.
3. Calibrate the gauge - see:
•
"Calibrating - for a Material" on page 18 and
•
"Calibrating - for a Coating" on page 20
..
8.2 SELECTING THE TRANSDUCER TYPE MANUALLY
Note: If not using a coating thickness transducer, you will need to select
a transducer type from the predefined list so that your gauge may
recall specific transducer properties.
Follow these steps to select your transducer type:
1. When the CONFIRM screen displays the 'UNIDENTIFIED PROBE
TYPE' message, press OK to display the predefined list of
transducer types (by diameter and frequency).
2. Using UP or DOWN, scroll through the transducer list until the
correct type is highlighted and then press ENTER.
3. Press OK to overwrite the existing transducer type with the newly
selected transducer type.
Your gauge will automatically advance to the Zero Probe menu.
8.3 TRANSDUCER - ZEROING
Setting the zero point for the transducer is important in the same way
that it is important for a mechanical micrometer. Zeroing takes into
account slight variations in the manufacturing process for maximum
accuracy. If zeroing is not carried out correctly, the measurements
taken by the gauge will be in error by some fixed value.
Your gauge has two zero probe options
•
Off Block or Automatic Probe Zero - The gauge conducts an
electronic zero
measurement modes)
•
On Block or Manual Probe Zero - Requires use of the zero block on the top of the gauge
(Pulse to echo mode only)
without the need for a zero block (All
