Calibration 2-21
•
Program the current source for 0A output using the :SOUR:CURR 0.0 command.
•
Note the multimeter reading.
•
Send the source and sense calibration commands using the multimeter reading for
the parameter. For example:
:CAL:PROT:SOUR 1E-6
:CAL:PROT:SENS 1E-6
•
Set the source to the positive full-range value using the :SOUR:CURR command.
For example, for the 1mA range:
:SOUR:CURR 1E-3
•
Note and record the multimeter reading.
•
Send the source and sense commands using the multimeter reading as the param-
eter. For example:
:CAL:PROT:SOUR 1.03E-3
:CAL:PROT:SENS 1.03E-3
•
Send the :SOUR:CURR 0.0 command to set the source current to 0A.
•
Note and record the multimeter reading.
•
Send the :CAL:PROT:SOUR command using the multimeter reading as the com-
mand parameter. For example:
:CAL:PROT:SOUR 1E-6
4.
Connect the 1
Ω
resistor and DMM to the Model 2430 INPUT/OUPUT jacks, as shown
in Figure 2-3. Select the DMM DC volts function.
5.
Repeat step 3 for the 3A range using the calculated current as follows: I = V/R, where V
is the DMM voltage reading, and R is the characterized value of the 1
Ω
resistor.
