■ *TST?
Table 2-5 lists the indications and limitations that will occur when the Self-Test command is applied to
the 58542 instrument. The Result, Minimum and Maximum indications are all given in millivolts.

Example: OUTPUT @PWR_MTR;*TST? ! QUERIES SELF-TEST RESULT
Response:
0 if all is OK, otherwise, it returns a value of 1.

Error Number Result Minimum Maximum Test Description
100 0 0 50 OUTPUT DAC
This test steps the analog output DAC from
0volts to 10volts in 1 volt steps, and measures
the resultant output voltage with the system ADC.
It then compares the results with the limits shown
to the left and, if it is outside any limit, it will set the
error number corresponding to that voltage level.

200 0 0 50 OFFSET DAC
This test steps the sensor input amplifier offset
DAC from 0volts to 5volts in 1volt steps, and
measures the resultant output voltage with the
system ADC. It then compares the results with the
limits stated to the left and, if outside any limit, it
will set the error number corresponding to that
voltage level.
