2.4.1 Connect the probe to the probe connector
2.4.2 Test probe
1. Hold the probe so that the lug on the probe connector faces the groove in the socket
on the top of the instrument.
ATTENTION! Do not push in the connector by force. Check position of lug and
groove.
2. Insert the probe connector straight into the probe socket all the way from the top.
3. Tighten the locking nut finger-tight. Do not use tools.
Removing the probe:
⇒ Loosen the locking nut and pull the probe upwards and out at the metal plug.
After connecting a probe to the probe connector, a self-test is automatically started. The
digital part, the analog part and the measuring sensors of the probe are checked for cor-
rect function. If a fault is detected that could affect the measurement, a corresponding
message is displayed and measurements are not possible.
WARNING
Probe is not working properly
Due to a defective probe, any high radiation levels that may be present cannot be
detected.
⇒ Observe the information displayed during and after the self-test of a probe. If there
is any doubt about the correct functioning of the probe, a test source (see accesso-
ries in the data sheet) can be helpful to check the probe.
⇒ In order to make the correct probe selection, you should always obtain knowledge
of the expected frequency and field strength before starting a measurement.
