DMP30 / DMP40 Measure
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, 53
• 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 not 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.
Two-tip probe: For specimens whose base materials have a magnetic
preferred direction, we recommend determining the measured reading by
taking the average of two measurements, whereby the probe is to be rotated
by 90° after the first measurement. Not relevant for the ISOSCOPE® gauge
models.
8.3 Before you start
The measuring area and the probe tip on the probe are clean, free of oil, dust,
etc.
The probe is connected to the gauge.
The gauge is acclimatized and the battery are sufficiently charged for the up-
coming measurement.
The desired batch is open in the gauge with the correct measurement settings.
