FERITSCOPE® DMP30 Measure
If all signal functions in the gauge are activated, the gauge reports the following
states:
Beeps
- Short beep = measured reading acquisition complete, second beep in addi-
tion if the specification limit is violated
- Long beep = block closure
Light signals
- Specification limit monitoring not active:
Green = measured reading acquisition successful
- Specification limit monitoring active:
Red = measured reading outside the specification limits, the measured
reading itself is also displayed in red
Gauge vibration
- Measured reading acquisition completed, second vibration in addition in
case of a specification limit violation or block closure
For the following measurement situations, we recommend setting the acquisi-
tion of the air reference value to Static:
- Measurements in cavities and pipes if the minimum lift off distance of
4 x the probe measurement range cannot be respected, 51
- Measurements in Scan measuring mode with a very high number of
measured reading acquisitions while the surface is being scanned
8.2 Handling the probe
In addition to the calibration, the way in which the probe is placed on the surface is
also crucial for a precise measurement. Measured reading acquisition via the probe.
Important notes for correctly handling the probe during the measurement
Always hold the probe at its grip sleeve.
Always place the probe perpendicular and gently on the surface.
For the measurement, place the probe quickly on the surface, do no t allow
the probe to hover over the specimen.
In default mode, a beep and a green light strip signals that the measured
reading has been acquired. Only then lift the probe off the surface, lift off
distance ≥ 4 x the probe measurement range.
