Send the following query command to the TW and record the return string as MEAS1 :
MEAS {1,2,3} :VOLT?
Calculate the offset value:
VALUE1 = RDGN1 – MEAS1
Send the offset value to the TW:
CAL {1,2,3} :MEAS:LOC:LOR:VOLT:OFFSET VALUE1
Measure the current offset by sending the following GPIB query and record the return
string as
MEAS1 :
MEAS {1,2,3} :CURR?
Calculate the offset value:
VALUE1 = -1.0 * MEAS1
Send the calculated offset to the TW:
CAL {1,2,3} :MEAS:LOC:LOR:CURR:OFFSET VALUE1
Set the TW to 220 volts DC by sending the following GPIB string:
SOUR {1,2,3} :VOLT:OFFSET 220
Wait for the DMM to settle. Take a DMM reading and record the value as RDGN1 .
Query the output voltage of the TW and record the return string as MEAS1 :
MEAS {1,2,3} :VOLT?
Set the TW to -220 volts DC by sending the following GPIB string:
SOUR {1,2,3} :VOLT:OFFSET –220
Wait for the DMM to settle. Take a DMM reading and record the value as RDGN2 .
Query the output voltage of the TW and record the return string as MEAS2 :
MEAS {1,2,3} :VOLT?
