Stability indicator
One bar - no readings are being taken
Less than 5 bars - reading is unstable and may be
inaccurate
More than 5 bars - reading is stable
Refer to "Read display" on page 12 and "Transducers" on page 20 for information on how to
achieve a stable measurement.
4.1 FRONT PANEL LIGHTS (CG50 & CG50DL ONLY)
Green light illuminates when:
• The alarm mode is active, and
• the measured thickness is greater than the alarm value.
Red light illuminates when:
• The alarm mode is active, and
• the measured thickness is less than the alarm value.

5 SETTING UP THE GAUGE

5.1 TRANSDUCER - ZEROING
Setting the zero point for the transducer is important for the same reason that setting the zero on a
mechanical micrometer is important. If the zero point of the transducer is not set correctly, all of the
measurements the gauge makes will be in error by some fixed number. When the zero point of the
transducer is set, this fixed error value is measured and automatically corrected for in all
subsequent measurements.
Though the gauge will remember the last zero point, it is generally a good idea to set the zero point
whenever the gauge is switched on, as well as any time a different transducer is used. This will
ensure that the zero point of the instrument is always correct.
The zero probe routine must be done prior to calibration.
