4.5.2 Connecting the probe to the optical input
4.5.3 Test probe
4.5.4 Attaching marking rings
The HP-01 and EHP-50F/GF field analyzers are connected to the optical input of the
FieldMan. A suitable optical cable is included with the probes.
Connecting a probe:
1. Go to GENERAL SETTINGS > CONNECTIVITY > OPTICAL INTERFACE and select
Probe.
2. Connect a suitable probe via the optical cable to the optical connector on the
FieldMan (see Fig. 2: 7).
⇒ For more information on using a probe via the optical link, refer to the operating in-
structions for the probe.
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.
Broadband probes are provided with a groove for a marking ring in the area of the con-
nector. Probes are generally supplied with a black ring. Users of different probes are
offered the possibility to distinguish the probes more easily by attaching colored rings.
The scope of delivery includes 5 colored rings for this purpose.
