Select source range.
Establish negative full-range polarity.
Read actual output value.
Calibrate sense function negative full scale.
Calibrate source function negative full scale.
Set output to 0V.
Read actual output value.
Calibrate sense function negative zero.
Calibration source function negative zero.
Establish positive full-range polarity.
Read actual output value.
Calibrate sense function positive full scale.
Calibrate source function positive full scale.
Set output to 0V.
Read actual output value.
Calibrate source positive zero.
1. Perform complete procedure for each range, where <Range> = 0.2, 2, 20, and 100, and<Source_value> = 0.2, 2,
20, and 100.
2. <DMM_Reading> parameter is multimeter reading from previous step.
3. Use :SYST:ERR? query to check for errors.
3. Calibrate the 10μA to 1A current ranges using the procedure summarized in Table 2-11.
For each range:
• Send the :SOUR:CURR:RANG command to select the source and sense range
being calibrated. For example, for the 1mA range, the command is:
:SOUR:CURR:RANG 1E-3
• Program the source to output the negative full-range value using the
:SOUR:CURR command. For example:
:SOUR:CURR -1E-3
• Note and record the multimeter reading.
• Use the multimeter reading as the parameter for the :CAL:PROT:SOUR and
:CAL:PROT:SENS commands. For example, a typical value for the 1mA range
would be:
:CAL:PROT:SOUR -1.025E-3
:CAL:PROT:SENS -1.025E-3
