Probe Zeroing (Twin Element Probes) - Cygnus 1 Ex Manual

Probe Zeroing (twin element probes)

Twin element probes must be zeroed to compensate for any wear or operating
temperature changes. The gauge will always perform a Probe Zero when first
turned on or when a twin element probe is connected.
If the probe gets significantly warmer during use this can cause a shift in the zero
position and thus introduce small errors in the thickness measurement. Typically, a
20°C (68°F) change in temperature the measurements can shift by 0.1 mm
(0.04").
It is recommended to frequently perform a Probe Zero
especially if conditions such as temperature are changing.
"A Probe Zero is Required" message is
1.
shown when a probe is connected.
Press the Zero function key to begin.
2. Wipe clean the face of the probe.
Press the √ key to start.
The gauge measures the probe zero
point. This takes a few seconds.
3. "Measuring probe zero" message is
displayed, followed by the probe zero
time in nanoseconds.
