Calibrate to an output level of
1.0000
µµ
A
. Adjust the output level of the
2000 instrument as described in step 2 until the voltage measured is:
100mV +/– 7.5
µµ
V
, i.e., a current of
1
µµ
A +/– 75pA
.
This output level may be measured directly by using:
ü
A calibration standard
100k
Ω
resistor and a high precision DMM,
or;
ü
A nullmeter to monitor the voltage drop across the standard resistor.
16. Calibrate to an output level of
10.000
µµ
A
. Adjust the output level of the
2000 instrument as described in step 2 until the voltage measured is:
100mV +/– 5
µµ
V
, i.e., a current of
10
µµ
A +/– 500pA
.
This output level may be measured directly by using:
ü
A calibration standard
10k
Ω
resistor and a high precision DMM, or;
ü
A nullmeter to monitor the voltage drop across the standard resistor.
17. Calibrate to an output level of
100.00
µµ
A
. Adjust the output level of the
2000 instrument as described in step 2 until the voltage measured is
100mV +/10
µµ
V
, i.e., a current of
100
µµ
A +/– l0nA
.
This output level may be measured directly by using:
ü
A calibration standard
1k
Ω
resistor and a high precision DMM, or;
ü
A nullmeter to monitor the voltage drop across the standard resistor.
18. Calibrate to an output level of
+10.00000
µµ
A
. Adjust the output of the
2000 instrument as described in step 2, until the voltage measured is
1.0V +/– 25
µµ
V
(assuming exact resistance of 100
k
Ω
), i.e., a current of
l0
µµ
A +/– 250pA
.
