Code Description of error Action to take
1 The amplif ier detect ed a probe, but a
valid Hall device was not detected.
Disconnect and reatt ach the probe to the amplifier.
Power cycle the am plifier.
Check probe t ransform er (def ective Hall device).
If these steps do not resolve the error, the amplifier needs service.
May also be caused by a shorted or open wire in the probe cable assembly.

The amplif ier cannot null out the
probe DC offset voltage.
Remove the probe from the circuit. Error 12 will most likely occur when the probe is
connected to an energized circuit when a Degauss/Autobalance routine is initiated.
