7.2 DIFFERENTIAL MODE - CG50 AND CG50DL ONLY
Your gauge includes Differential Mode which allows it to display the positive or negative difference
from an entered nominal value.
To switch differential mode on/off and enter the value:
Model CG50
1. Switch on the gauge.
2. Press the dIFF key.
The gauge will display dIFF OFF or dIFF
followed by a thickness value and flashing
MM (or IN), depending on which mode the
gauge is in.
3. Repeat step 2 to switch differential mode
on or off.
4. Assuming dIFF value flashing MM is
displayed, use the UP and DOWN arrow
keys to scroll to the desired nominal
thickness value.
5. Press the dIFF key once again to select
the nominal value entered.
7.3 ALARM - CG50 AND CG50DL ONLY
The Alarm feature of the Models CG50 and CG50DL allows the user to set an audible and visual
alarm when taking measurements.
If the alarm is switched on, the green light on the front panel of the gauge is illuminated. If the
measurement falls below the value set by the user, a red light shows on the front panel of the gauge
and the beeper is sounded (if it is switched on).
Use of the red light and beeper improves the speed and efficiency of the inspection process by
eliminating constant viewing of the reading displayed.
