7.4 Measurement
Place the device with the probe perpendicular to the measurement surface at the point to be
measured and press the device lightly towards the measurement object. Hold the device still
during measurement to avoid measurement errors. The successful measurement is
acknowledged by a sound and the measured value is shown on the display.
The V grooves on the probe help you to align the device on convex measurement objects.
7.4.1 Single / continuous measurement
The setting "Single measurement" is indicated by "SNG" on the left-hand side of the display.
For single measurements, observe a time interval of 2 seconds between two measurements.
To avoid scratches and damage to the measured object and the probe, lift the meter off the
surface between measurements.
To switch to the measurement mode "continuous measurement", proceed as described in the
menu.
The setting "continuous measurement" is indicated by "CTN" on the left-hand side of the display.
Traces and scratches can occur on the measured object during continuous measurement.
