Voltage range calibration adjustment commands
Step Command Description
1 :SOUR:VOLT:RANG <Range> Select the source range.
2 :SOUR:VOLT -<Range> Establish negative polarity.
3 DMM reading 1.** Read the actual output value on the DMM.
4 :CAL:ADJ:SOUR <DMM_Reading1> Adjust the source function negative full scale.
5 :SYST:ERR? Check Model 2461 for errors.
6 :CAL:ADJ:SENS <DMM_Reading1> Adjust the sense function negative full scale.
7 :SYST:ERR? Check Model 2461 for errors.
8 :SOUR:VOLT 0.0 Set the output to 0 V.
9 DMM reading 2.** Read the actual output value on the DMM.
10 :CAL:ADJ:SOUR <DMM_Reading2> Adjust the source function negative zero.
11 :SYST:ERR? Check Model 2461 for errors.
12 :CAL:ADJ:SENS <DMM_Reading2> Adjust the sense function negative zero.
13 :SYST:ERR? Check Model 2461 for errors.
14 :SOUR:VOLT +<Range> Establish positive polarity.
15 DMM reading 3.** Read the actual output value on the DMM.
16 CAL:ADJ:SOUR <DMM_Reading3> Adjust the sense function positive full scale.
17 :SYST:ERR? Check Model 2461 for errors.
18 CAL:ADJ:SENS <DMM_Reading3> Adjust the source function positive full scale.
19
:SYST:ERR?
Check Model 2461 for errors.
20 :SOUR:VOLT 0.0 Set the output to 0 V.
21 DMM reading 4.** Read the actual output value on the DMM.
22 :CAL:ADJ:SOUR <DMM_Reading4> Adjust the source positive zero.
23 :SYST:ERR? Check Model 2461 for errors.
* Perform the complete procedure for each range, where
<Range>
= 0.2, 2, 7, 10, 20, and 100.
** The
<DMM_Reading n >
parameter is the DMM reading from the previous step.
Each range requires:

Four
CAL:ADJ:SOURce
commands (full scale and zero for each polarity)

Three
CAL:ADJ:SENSe
commands (full scale for each polarity, and zero)
Step 3. Current adjustment
Keithley Instruments recommends two different connection configurations for current adjustment:

For the 1 µA to 1 A ranges, use the connection diagrams in Connections for the 1 µA to 1 A
ranges (on page 2-5).

For the 4 A to 10 A ranges, use the connection diagrams in Connections for the 4 A to 10 A
ranges (on page 2-5).
The following topics describe how to do current adjustment for each of these configurations.
