Command Reference B-9
Detecting calibration errors
If an error occurs during any calibration step, the Model 2400 will generate an appropriate
error message. Several methods to detect calibration errors are discussed in the following
paragraphs.
Reading the error queue
As with other Model 2400 errors, any calibration errors will be reported in the error queue.
(You can read the error queue by using the :SYST:ERR? query.)
Error summary
Table B-4 summarizes calibration errors. These errors will occur under the following
conditions.
Error 500/501 Will occur if you do not set the calibration date or calibration due date.
Error 502 Will occur when the :CAL:PROT:SENS or :CAL:PROT:SOUR command is
sent with a parameter that cannot be placed into any of the defined numeric
ranges.
Error 503/504 Will occur when the source/compliance DAC calibration constants generate
an invalid DAC setting. All of the source/compliance DAC calibration
constants are verified each time a :CAL:PROT:SOUR command is
processed and when the Model 2400 is first turned on. This error generally
occurs when the Model 2400 source circuitry is defective.
Error 505 Will occur when a :CAL:PROT:SOUR command generates an invalid
source offset calibration constant.
Error 506 Will occur when a :CAL:PROT:SOUR command generates an invalid
source gain calibration constant.
Error 507 Will occur when a :CAL:PROT:SENS command generates an invalid
measurement offset calibration constant.
