Calibration 3
Model N6705 Service Guide 51
Step 4.
Calculate the shunt current (I=V/R) and enter the data.
Enter the calculated value into the data
field and then select Next.
Select the second current calibration point.
The second calibration point is
automatically selected “Enter P2 measured
data” should be displayed.
*OPC?
Calculate the shunt current (I=V/R) and enter the data.
Enter the calculated value into the data
field and then select Next. When
calibration is complete, select Close.
Peak Current Limit Calibration
Note that for models N6753A through N6756A, the peak current limit
calibration is valid for 5 years.
Step 1.
Connect only the electronic load or equivalent resistor (up to 500W
rating) across the output terminals for the first calibration point:
N6751A /N6752A: 25 Ω resistor (do not use electronic load) 4 Ω resistor (do not use electronic load)
N6753A: Electronic load set to 26.25A, CC mode
(0.6 Ω equivalent, including lead resistance)
Electronic load set to 13.12A, CC mode
(1.2 Ω equivalent, including lead resistance)
N6754A: Electronic load set to 10.5A, CC mode
(3.8 Ω equivalent, including lead resistance)
Electronic load set to 5.25A, CC mode
(7.6 Ω equivalent, including lead res.)
N6755A: Electronic load set to 43.75A, CC mode
(0.37 Ω equivalent, including lead resistance)
Electronic load set to 21.88A, CC mode
(0.73Ω equivalent, including lead resistance)
N6756A: Electronic load set to 17.5A, CC mode
(2.3 Ω equivalent, including lead resistance)
Electronic load set to 8.75A, CC mode
(8.75Ω equivalent, including lead resistance)
Select peak current limit calibration.
From the Calibration menu, select
Miscellaneous, Peak Current Limit. Then
select Start.
Select the first current calibration point.
The calibration is automatic.
