Recommended :CALibration:PROTected:SOURce parameter ranges
Source
range (negative full scale)
0.2V -0.18 to -0.22
2V -1.8 to -2.2
20V -18 to -22
100V -90 to -110
10μA -9E-6 to -11E-6
100μA -90E-6 to -110E-6
1mA -0.9E-3 to -1.1E-3
10mA -9E-3 to -11E-3
100mA -90E-3 to -110E-3
1A -0.9 to -1.1
3A -2.7 to -3.15
Note: Actual allowable parameter ranges are ±50% of full range for zero parameters, 75% of full scale to 150% of full
scale for full-range parameters, but ranges listed above should be observed for optimum calibration.
active source function/range point will be calibrated using the corresponding
parameter.
Note that parameters for a given source function and range may be sent in
any order; however, once one :CAL:PROT:SOUR command executes, the
other three must also be executed, or an error number -200, "Execution
error" will occur when the :CAL:PROT:SAVE command is processed at the
end of the calibration procedure.
Because the source is calibrated for both positive and negative values, two
zero calibration points are required. The Model 2425 automatically uses the
appropriate zero parameter based on whether the source polarity is positive
or negative.
