Zero
PosiTector 200 probes must be periodically zeroed using the
ZERO menu option to compensate for both extreme temperature
and probe wear effects. Before using, allow the probe to reach
ambient temperature.
If measurements will be made in extreme hot or cold temperatures,
it is recommended to ZERO the probe in the working environment.
If measurements will be made on rough substrates
,
it is
recommended to periodically ZERO the probe to compensate for
wear.
1. Make sure the Gage is on and the probe is wiped clean.
2. Hold probe in air, away from substrate.
3. Select the Zero menu option.
4. When complete, Gage will double beep and display “----”.
Set Range
The measuring range of each probe can be changed depending on
the specific application or the expected thickness range of the
coating system.
For most applications, the default range values do not have to be
adjusted. But some conditions, like surface roughness, may cause
the Gage to display very low or non-repeatable readings. In this
case, the low range may be increased to cause the Gage to only
display readings above the Lo value set by the user.
To adjust Set Range values...
1. Select or with the Up and Down buttons.
2. Use the (-)(+) buttons to decrease/increase the displayed value.
IMPORTANT:
The PosiTector 200 interprets the largest “echo” or “echoes”
within the selected range as the coating/coating or
coating/substrate echo. If the coating thickness is outside this
range, incorrect or dashed readings may occur.
