Keithley 2010 Service Manual

Manufacturing calibration commands
The following three calibration steps are only performed at the factory or when the unit has
been repaired:
:CALibration:PROTected:AC:STEP14 1V AC at 3Hz
:CALibration:PROTected:AC:STEP15 1V AC at 1kHz
:CALibration:PROTected:DC:STEP0 Rear terminal short circuit
:AC:STEP<14|15> (CALibration:PROTected:AC:STEP<14|15>)
Purpose To program individual AC manufacturing calibration steps.
Format :cal:prot:ac:step14 <Cal_voltage>
:cal:prot:ac:step15 <Cal_frequency>
Parameter <Cal_voltage> = 1 [1V nominal]
<Cal_frequency> = 1E3 [1kHz nominal]
Description The :AC:STEP14 and :AC:STEP:15 commands program the two
manufacturing AC calibration steps. The appropriate signal must be
connected to the instrument when programming each step, as summarized by
the parameters listed above.
Examples :CAL:PROT:AC:STEP14 1 Program AC step 14.
:CAL:PROT:AC:STEP15 1E3 Program AC step 15.
:DC:STEP0 (:CALibration:PROTected:DC:STEP0)
Purpose To perform rear terminal short-circuit calibration.
Format :cal:prot:dc:step0
Description :STEP0 performs the rear short-circuit calibration step in the manufacturing
calibration procedure. Connect a low-thermal short (Model 8610) to the rear
panel input jacks, and select the rear inputs before sending this command.
Example :CAL:PROT:DC:STEP0 Perform rear short-circuit calibration.
Remote error reporting
Methods to detect and determine the nature of calibration errors are discussed in the
following paragraphs.
