ETS-Lindgren FM5004 Field Monitor (Archived) - Manual (Page 16)

Z EROING
Not all probes have a zero function. For information on zeroing a
probe, see the probe manual.
When a probe receives a zero command from the FM5004, the probe must be in
a zero field. The processor directs the multiplexer to perform a normal read cycle
on all axis signals; this procedure is executed for all 24 settings (four ranges,
three axes per range, two antennas per axis). When the processor receives
these readings, it stores them in a special register, and then these values are
subtracted from all subsequent measurements. Therefore, a probe that is zeroed
when it is not in a zero field environment will give erroneous readings.
