Calibration and Maintenance
69
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 be-
tween 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
.
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.
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
.
