Performing 2 VDC Calibration
Step 4: +20V DC calibration
1. After completing 2VDC calibration, the instrument will
display the following:
CONNECT 20 VDC CAL
2. Set the DC calibrator output to +20.000000V.
3. Press ENTER, and note that the instrument displays the
calibration voltage:
VOLTAGE = 20.0000000
(At this point, you can use the cursor and range keys to
set the calibration voltage to a value from 9.8 to 21V if
your calibrator cannot source 20V).
4. Press ENTER. The instrument will display the follow-
ing message to indicate it is performing 20V DC calibra-
tion:
Performing 20 VDC Calibration
Step 5: 20k¾ calibration
1. After completing 20VDC calibration, the instrument
will display the following:
CONNECT 20kOHM RES
2. Set the calibrator output to 19.0000k¾, and turn external
sense on.
3. Press ENTER, and note that the Model 2001 displays
the resistance calibration value:
OHMS = 20000.000

4. Using the cursor and range keys, set the resistance value
displayed by the Model 2001 to the exact resistance val-
ue displayed by the calibrator. (The allowable range is
from 9k¾ to 21k¾.)
5. Press ENTER, and note that the instrument displays the
following during 20k¾ calibration:
Performing 20 kOHM Calibration
Step 6: 1M¾ calibration
1. After completing 20k¾ calibration, the instrument will
display the following:
CONNECT 1.0 MOHM RES
2. Set the calibrator output to 1.00000M¾, and turn exter-
nal sense off.
3. Press ENTER, and note that the Model 2001 displays
the resistance calibration value:
OHMS = 1000000.000
4. Using the cursor and range keys, set the resistance value
displayed by the Model 2001 to the exact resistance val-
ue displayed by the calibrator. (The allowable range for
this parameter is from 800k¾ to 2M¾.)
5. Press ENTER, and note that the instrument displays the
following during 1M¾ calibration:

Step 7: Open-circuit calibration
1. At this point, the instrument will display the following
message advising you to disconnect test leads:
