Protek Z9216 - Error Messages; Operational Errors; Self-test Errors

Error Messages
The following lists explain all of the error messages that the Model Z9216 can generate. The
messages are divided into operational errors (errors in using the instrument), self-test errors, 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
Meaning
Bias For C The Model Z9216 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.
Cony Error An A/D conversion that is either too short or too long can produce this error.
Continued errors may indicate a hardware problem.
Float Error An error in a floating point math routine occurred.
F-R Error Frequency-Range incompatibility. The 100kΩ range may not be used with the
100 kHz drive frequency.
Over Load The Model Z9216 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.
Over Range The impedance is beyond the Model Z9216 measurement ability on the current
range. If range hold is active, change to a higher range.
Range Error Parameter in command is out of allowed range for that command.
Rcl Error Non-volatile RAM has been corrupted. User calibrations and settings may be lost.
If this error occurs frequently, check the battery.
Syn Error The command syntax is invalid. See the programming section for correct
command syntax.
Self-test Errors
These errors may occur during the Model Z9216 self-test. In general, these messages indicate Model
Z9216 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.
Message
Status Meaning
AD Error 6 The A/D converter failed its test. The test measures 0 V and ±2 VDC.
Bias Error 7 The Model Z9216 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 Model Z9216 ROM has a checksum error. XX is the checksum value.
CPU Error 1 The Model Z9216 has detected a problem in its CPU.
