2 CALIBRATION USING AN ULTRA/SCAN PROBE
When using an Ultra/Scan Probe in "Scan" or "Auto Repeat" mode , the probe end cap must be fitted to avoid
damage to the probe tip and the gauge can only be calibrated using either the "Smooth" or "Rough / 2 Point"
calibration methods.
Scale 1: For "Smooth" calibration a 1500µm (60mils) nominal foil and uncoated base / zero plate is required.
For "Rough / 2 Point" a 50µm (2mil) nominal foil is also required.
Scale 2: For "Smooth" calibration a 4mm (160mils) nominal foil and uncoated base / zero plate is required.
For "Rough / 2 Point" a 50µm (2mils) nominal foil is also required.
CONNECTING THE ULTRA/SCAN PROBE
1 Rotate the probe plug to align the pins
2 Screw in the collar - clockwise
CALIBRATING WHEN IN "SCAN" OR "AUTO REPEAT" MODE :
1 Press the Cal softkey and select "Cal Method"
2 Select "Smooth" or "Rough / 2 Point" followed by "Calibrate"
3 Follow the on screen instructions
In order to avoid probe tip damage during "Scan" or "Auto Repeat" mode, a probe cap must be fitted. During the
calibration procedure if, when asked by the gauge, no cap is to be used, the gauge will automatically revert to
"Standard" measurement mode.
b
To select the measurement mode go to Menu/Setup/Measurement Mode.
c
The Scale 2 probe is supplied with a 3mm (120mils) and 1mm (40mils) foil which can be used to make a 4mm (160mils) foil.
d
If an alternative calibration method has been selected, the gauge will prompt the user to select either "Smooth" or
"Rough / 2 Point".
