614 DC 1000V zero failed
This test configures to the 1000V dc range
with no input applied. A 20ms ADC measurement is performed and the
result is checked against a limit of 0V
±
5 mV.
615 Ohms 10 uA source failed
This test configures to the 1000V dc
range with the internal 10M 100:1 divider R204 connected across the
input. The 10
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.
616 DC current sense failed
This test configures to the 3A dc range.
A 20ms ADC measurement is performed and the result is checked
against a limit of 0A
±
5A. This test confirms that the dc current sense
path is functional. The test limit is set wide because K303
does not
open the current input during self-test. This test should catch a dc
current sense failure without causing false failures when current inputs
are applied during self-test.
617 Ohms 100 uA source failed
This test configures to the 1000V
dc range with the internal 10M 100:1 divider R204 connected across
the input. The 100
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.
618 DC high voltage attenuator failed
This test configures to the
1000 V dc range. 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.
619 Ohms 1 mA source failed
his test configures to the 1000V dc
range with the internal 10M 100:1 divider R204
connected across the
input. The 1mA 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.
620 AC rms zero failed
This test configures for the 100mV ac range
