You can power the FH 52 either from non-rechargeable or from rechargeable batteries
(accumulators). Rechargeable batteries have to be charged externally.
The indicator is configured for batteries with a cell voltage of 1.5 V. If rechargeable batteries
with a lower cell voltage are used, the indicator will never indicate completely full batteries,
even if they are fully charged. However, this does not mean that they cannot be used.
Switch off the device using the
On/Off
key before opening the battery compartment and
removing the batteries. This ensures that the device settings and the measured values are saved.
Important!
You should remove the batteries from the FH 52 if the device will not be
used for a longer time. This will avoid damage due to leaking batteries.

Probes
Two standard probes are available for the FH 52: a transverse and an axial probe. The
transverse probe has a Hall sensor that is mounted parallel to the probe axis. It measures a
magnetic field that is aligned in one direction perpendicular to the probe axis.

The axial probe has the Hall sensor mounted perpendicular to the probe axis which measures
magnetic fields parallel to the probe axis.
