Command
Sequence
CAL:CONF:RES
connect reference resistor to Calibration 
Bus
*OPC? or SYST:ERR?
must wait for CAL:CONF:RES to 
complete
(now measure ref resistor with external DMM)
CAL:VAL:RES  <measured value>
Send measured value to module
CAL:STORE ADC
Store cal constants in non-volatile 
memory (used only at end of complete 
cal sequence)
CALibration:CONFigure:VOLTage
CALibration:CONFigure:VOLTage  <range>,<zero_fs
connects the on-board 
voltage reference to the Calibration Bus. A measurement of the source voltage can 
be made with an external multimeter connected to the H Cal and L Cal terminals on 
the Terminal Module or the V HV L
Ω H, and Ω L terminals on the Cal Bus 
connector when not using a terminal module. The <range> parameter controls the 
voltage level available when the <zero_fs> parameter is set to FSCale (full scale).
Parameters
Comments
The <range> parameter must be within
 ±5% of one of the five following values:
0.0625 V dc, 0.25 V dc, 1 V dc, 4 V dc, 16 V dc.  This parameter may be 
specified in millivolts (mv).
The expected FSCALE output voltage of the calibration source will be 
approximately 90% of the nominal value for each range, except the 16 V range 
where the output is 10 V.
