Voltage calibration initialization commands

Command
*RST
:SOUR:FUNC VOLT
:SENS:CURR:PROT 0.1
:SENS:CURR:RANG 0.1
:SOUR:VOLT:PROT MAX
:SYST:RSEN OFF
:CAL:PROT:CODE 'KI002420' Unlock cal.
:OUTP:STAT ON
* Remote sensing may be used if desired, but is not essential when using the recommended
digital multimeter. To use remote sensing, send :SYST:RSEN ON.
• Note and record the multimeter reading.
• Send the source and sense commands using the multimeter reading as the parameter.
For example:
:CAL:PROT:SOUR 1.997
:CAL:PROT:SENS 1.997
• Send the SOUR:VOLT 0.0 command to set the source voltage to 0V.
• Note and record the multimeter reading.
• Send the :CAL:PROT:SOUR command using the multimeter reading as the command
parameter. For example:
:CAL:PROT:SOUR -1.02E-3
