15-4 6517B-901-01 Rev. C / August 2015

2 uA to 200 uA range voltage offset

To calibrate the voltage offset for each range:

1. Connect a 10 K resistor between the Model 6517B input HI and input LO. Set the DMM range to

1 VDC.

:CAL:PROT:VOFF:STEP 3

:CAL:PROT:VOFFSETZ

2. Allow the input to settle for 10 seconds, then take the DMM voltage reading.

:CAL:PROT:VOFFZERO <dmm voltage reading>

3. Connect a 1 K resistor between the Model 6517B input HI and input LO. Set the DMM range

to 1 V DC.

:CAL:PROT:VOFF1

4. Allow the input to settle for 10 seconds, then take the DMM voltage reading.

:CAL:PROT:VOFF2 <dmm voltage reading>

:CAL:PROT:VOFF3

5. Allow the input to settle for 10 seconds, then take the DMM voltage reading.

:CAL:PROT:VOFF4 <dmm voltage reading>

2 mA to 20 mA range voltage offset

To calibrate the voltage offset for each range:

1. Connect a 10  resistor between the Model 6517B input HI and input LO. Set the DMM range to

1 V DC.
