6.4 Checking for proper operation
WARNING
Probe is not operating properly
Possibly present high radiation values are not recog-
nized.
⇒
Check probes for proper operation with a signal source
before using this measuring instrument. This is espe-
cially important for thermocouples because the sen-
sors can be affected by various mechanical and
environmental stressors.
Narda offers portable sources to accomplish this im-
portant step (see
Accessories
on page 53).
⇒
Before beginning any RF radiation measurement, al-
ways advise yourself of the frequencies and field
strengths that you could expect to encounter.
