possible to see the damage to a fuse, so it can be helpful to measure it with an ohmmeter.

If it is damaged, replace it with a 250V, F250mA fuse. Replace the fuse holder and fuse

The following lists explain all of the error messages that the 9216A can generate. The
o
messages are divided into operational errors (errors in using the instrument), self-test er-
r
rors, and calibration errors. The messages are listed alphabetically.

Operational Errors

These error messages may appear during normal front-panel operation and generally are
warnings for incorrect operation.
Message
Bias For C
Cony Error
Float Error
F-R Error

Rcl Error
Syn Error

Self-test Errors

These errors may occur during the 9216A self-test. In general, these messages indicate
9216A hardware problems. If the errors occur repeatedly, the unit may have an electrical
problem. The messages are listed alphabetically. Also listed is the status value returned
by the *TST? command.

Meaning
The 9216A DC bias function may only be used for capacitance
measurements. Set the parameter mode to either C+D or C+R to use
DC bias.
An A/D conversion that is either too short or too long can produce this
error. Continued errors may indicate a hardware problem.
An error in a floating point math routine occurred.
Frequency-Range incompatibility. The 100k range may not be used
with the 100 kHz drive frequency.
The 9216A input is overloaded. This can happen transiently as parts
are changed or if a part with too small an impedance is measured on
the constant drive voltage setting.
The impedance is beyond the 9216A measurement ability on the cur-
rent range. If range hold is active, change to a higher range.
Parameter in command is out of allowed range for that command.
Non-volatile RAM has been corrupted. User calibrations and settings
may be lost. If this error occurs frequently, check the battery.
The command syntax is invalid. See the programming section for
correct command syntax.
Status Meaning
6 The A/D converter failed its test. The test measures 0 V and
2 VDC.
