6.2.2 Setting the measuring range
!
Note!
• The choice of measuring range (0 to 500 pF and 0 to 1600 pF) depends on the function of the
probe.
• If the probe is used as a limit switch, you can retain the factory setting of 0 to 500 pF.
• If the probe is used for two-point control, the following recommendations apply for vertical
installation:
– Measuring range from 0 to 500 pF for probe lengths up to 1 m
– Measuring range from 0 to 1600 pF for probe lengths up to 20 m
Partially insulated probes are only suitable for nonconductive bulk solids (see also Chap. 8 on
ä 77).
To set the range to 0 to 1600 pF, proceed as follows:
1. Turn the function switch to position 4.
2. Press the "–" key for at least 2 seconds until the green LED 2 lights up.
3. Release the "–" key when the green LED 2 lights up.
Turn the function switch to position 2 to continue the calibration.
