6. Use the key and the key to adjust the displayed thickness up or down, until it
matches the thickness of the sample piece.
7. Press the key to confirm. The hint will changes to “NO2”, indicating measuring the second
calibration point.
8. Repeat steps 3 through 7. The hint will change back to “DPC”.
9. The gauge is now ready to perform measurements within this range.
4.7 Scan mode
While the gauge excels at making single point measurements, it is sometimes desirable to
examine a larger region, searching for the thinnest point. The gauge includes a feature, called
Scan Mode, which allows it to do just that.
In normal operation, the gauge performs and displays four measurements every second,
which is quite adequate for single measurements. In Scan Mode, however, the gauge performs ten
measurements every second, and displays the readings while scanning. While the transducer is in
contact with the material being measured, the gauge is keeping track of the lowest measurement it
finds. The transducer may be “scrubbed” across a surface, and any brief interruptions in the signal
will be ignored. When the transducer loses contact with the surface for more than two seconds, the
gauge will display the smallest measurement it found. When the transducer is removed from the
material being scanned, the gauge will display the smallest measurement it found.
On the 【Test Set】－>【Work Mode】menu item, press to toggle between single point
mode and scan mode.
4.8 Resolution
The Limit Set feature of the gauge allows the user to set an audible and visual parameter when
taking measurements. If a measurement is beyond the limit range, set by the user, the beeper will
sound, if enabled. This improves the speed and efficiency of the inspection process by eliminating
constant viewing of the actual reading displayed. The following section outline how to enable and
set up this feature:
1. On the 【Test Set】->【Tolerance Limit】 menu item，press the key to activate the limit set
screen.
2. Use the key, the key and the key to change the bottom limit and the upper limit
value to the desired values.
3. Press the key to confirm the change and return to the previous screen, or press the
key to cancel the change.
4. If the limit setting exceeds the measurement range, the gauge will remind you to re-set. If the
bottom limit is larger than the upper limit, the values will be exchanged automatically.
4.9 Resolution
The gauge has selectable display resolution, which is 0.1mm and 0.01mm.
On the 【Test Set】->【Resolution】 menu item, press the key to switch between “High”
and “Low”.
4.10 Unit Scale
On the 【Test Set】->【Unit】 menu item，press the key to switch back and forth between
Engilish and metric units.
