Bias Error 7 The 9216A internal DC bias source failed its test.
Cal Error 4 The RAM calibration data has become corrupt. The factory
values will be reloaded from ROM. This message is not a
problem unless it occurs frequently, which could indicate a
problem with the battery backup circuits.
Code Err XX 2 The 9216A ROM has a checksum error. XX is the checksum
value.
CPU Error 1 The 9216A has detected a problem in its CPU.
Data Error 3 CPU RAM failed a read/write test.
Det Error 6 The square wave multiplier failed its DC rejection test.
Drv Error i 7 The output drive circuitry failed its test. i is an error code indi-
cating the failure point.
i error
0 100 Hz amplitude failure
1 120 Hz amplitude failure
2 1 kHz amplitude failure
3 10 kHz amplitude failure
4 100 kHz amplitude failure
5 0.25 V amplitude attenuator failure
6 0.1 V attenuator failure
Freq Error i 5 The frequency clock generator failed its test. i is an error code
indicating the failure point.
i error
0 100 Hz failure
1 120 Hz failure
2 1 kHz failure
3 10 kHz failure
4 100 kHz failure
Gain Error 8 The instrumentation amplifier failed its gain test. i is an error
code indicating the failure point.

Out Error 9 The source impedance selection circuitry failed its test. This
error can occur if a part is in the fixture during the test. i is an
error code indicating the failure point.
