This output level may be measured directly by using:
 A high precision DMM, or;
 The preferred method of using a nullmeter to monitor the deviation between this instrument’s output level and that of a precision calibrated
10V source.
8. Calibrate to an output level of 0.00000A. Adjust the output level of the
2000 instrument as described in step 2, until the voltage measured
is: 0.0 +/–2.5V, i.e., a current level of 0 +/– 25pA.
This output level may be measured directly by using:
 A calibration standard 100K resistor and a high precision DMM, or;
 A nullmeter to monitor the voltage drop across the standard resistor
9. Calibrate to an output level of 1.0000A. Adjust the output level of the 2000
instrument as described in step 2 until the voltage measured is:
100mV +/– 7.5V, i.e., a current of 1A +/– 75pA.

10. Calibrate to an output level of 10.000A. Adjust the output level of the 2000
instrument as described in step 2 until the voltage measured is:
100mV +/– 5V, i.e., a current of 10A +/– 500pA.
