6
-8 volt supply low -
7
-8 volt supply high - The negative eight volt
supply to the analog circuitry is beyond
specification. The instrument must be returned
for service if these error messages persist.
8
Offset voltage low -
9
Offset voltage high - The probe offset voltage
is beyond specification. Check that the ambient
RF field at the probe is zero, then check the
supply voltages. If the supply voltage readings
are within specification, the probe/preamp
assembly should be replaced. If offset voltage
is still beyond specification, the instrument
must be returned for service.
10 Bias voltage low -
11 Bias voltage high - The probe bias voltage is
beyond specification. Check the negative eight
volt supply level. If the supply voltage is within
specification, the probe/preamp assembly
should be replaced. If the bias voltage is still
beyond specification, the instrument must be
returned for service.
15 Missing interrupt interval - The microprocessor
is faulty; return the instrument for service.
16 Stim test low -
17 Stim test high - A fault exists in the RF signal
processing path. Replace the probe/preamp
assembly; if the error persists, return the
instrument for service.
