1.3 Sources of Danger
The field strength meter FH 55 is operated with battery power or with a special mains power
supply. At this point, for reasons of work-place safety and accident prevention the sources of
danger emanating from such a device will be especially pointed out. The respective instructions
to the operator and owner of the field strength meter are to be strictly adhered to.
Danger!
Under no circumstances the equipment must come into contact with liquid
mediums, such as water, oil, etc. If in spite of all precautions taken, such a
medium does come into contact with the electronics of
the FH 55, there is considerable danger for the smooth operation of the
device!
In this case the device must be shut down immediately by pulling the line
power plug.
The equipment must similarly be switched off when being cleaned. Never
clean with water! Dry cloths only to be used for cleaning!
Danger!
The Hall probe must never be brought into contact with an electrical voltage
conductor. The paint on the probe surface is not an electrical insulation.
Disregard of this warning can cause danger to life of the user. Additionally,
the device and the probe can be damaged.
