B-12 Calibration Reference Model 2701 Service Manual
:STEP8
(:CALibration:PROTected:DC:STEP8)
Purpose To program the 100kΩ 4-wire comprehensive calibration step.
Format :cal:prot:dc:step8 <Cal_resistance>
Parameter <Cal_resistance> = 90E3 to 110E3 [Ω]
Description :STEP8 programs the 100kΩ 4-wire resistance comprehensive calibration
step. The allowable range of the calibration resistance parameter is from
90E3 to 110E3, but 100E3 is recommended for best results.
Example :CAL:PROT:DC:STEP8 100E3 Program 100kΩ step.
:STEP9
(CALibration:PROTected:DC:STEP9)
Purpose To program the 1MΩ comprehensive calibration step.
Format :cal:prot:dc:step9 <Cal_resistance>
Parameter <Cal_resistance> = 900E3 to 1.1E6 [Ω]
Description :STEP9 programs the 1MΩ comprehensive calibration step. The allowable
range of the calibration resistance parameter is from 900E3 to 1.1E6. Use
the 1E6 value whenever possible or the closest possible value.
Example :CAL:PROT:DC:STEP9 1E6 Program 1MΩ calibration step.
:STEP10
(CALibration:PROTected:DC:STEP10)
Purpose To program the 10mA comprehensive calibration step.
Format :cal:prot:dc:step10 <Cal_current>
Parameter <Cal_current> = 9E-3 to 11E-3 [A]
Description :STEP10 programs the 10mA comprehensive calibration step. The allow-
able range of the calibration current parameter is from 9E-3 to 11E-3. Use
the 10E-3 value whenever possible for best results.
Example :CAL:PROT:DC:STEP10 10E-3 Program 10mA step.
