604 A/D noisy test failed
This test configures to the 10V dc range
with the internal 0V. A 20ms ADC measurement is performed and the
result is checked against a limit of 0V
±
20uV
605 N2 calibration parameter failed
This error message indicates
that N2 calibration parameter is out of range.
606 N3 calibration parameter failed
This error message indicates
that N3 calibration parameter is out of range.
607 Buffer1 offset out of range
This procedure is to test the offset
of buffer U507. The result is checked against a limit of 0
±
0.1mV
608 Buffer2 offset out of range
This procedure is to test the offset
of buffer U508. The result is checked against a limit of 0
±
0.1mV

612 Ohms 500 nA source failed
This test configures to the 10V dc
range with the internal 10M 100:1 divider R204 connected across the
input. The 500nA ohms current source is connected to produce a
nominal 5V signal. A 20ms ADC measurement is performed and the
result is checked against a limit of 5V
±
1V.
613 Ohms 5 uA source failed
This test configures to the 1000V dc
range with the internal 10M 100:1 divider R204 connected across the
input. The 5
µ
A ohms current source is connected. The compliance
limit of the current source is measured. A 20ms ADC measurement is
performed and the result is checked against a limit of 0.12V
±
0.01V.
