4 Maintenance

4.1 Maintenance Plan

WHAT?
Checking the instrument and the
accessories for damages
Calibrating the instrument and
probe(s)
The checks shall be periodically repeated and documented.

4.2 Checking for Damage

The FH 52 and all accessories must be checked once a month for damages. If any of the
components, in particular the instrument housing, a probe or an optional line power supply (AC
adapter) are damaged, the equipment must only be used if it has been cleared for operation by
an authorized person. The damaged parts shall be replaced or sent to the manufacturer (Magnet-
Physik) for repair as soon as possible.

4.3 Calibration

Only regular calibration ensures accurate and reliable measuring results.
The FH 52 and the probe(s) should be calibrated using suitable references normally once a year.
We recommend having this calibration carried out by the manufacturer (Magnet-Physik) or an
authorized calibration laboratory.

4.4 Troubleshooting

Using the Test menu (chapter 3.3.16), you can carry out a self-test of the FH 52 and the
connected probe.
Furthermore some problems that you might face while operating the FH 52 are listed below:
• The instrument cannot be switched on using the
If you use the device with batteries, these might have become empty. Replace the
batteries or connect the device to a USB power supply or a computer.
If you are using a USB power supply (AC adapter), verify that the power supply is
working and that the line socket that you are using is powered.
If you have connected the USB power supply while the FH 52 was operational in
battery mode, the FH 52 might have entered standby mode. In this case disconnect the
USB power supply and wait approximately 30 seconds, so that the internal capacitors
can discharge. Then switch on the FH 52 in battery mode and switch it off again. Then
connect the USB power supply while the FH 52 is off.
If you have connected the FH 52 to a computer which is in standby mode, also the
