Points of Measurement
Note:
Use a digital voltmeter
(DC setting) to measure voltages
against ground (earth). No
particular points of measurement
are defined for this procedure; for
this reason, use a thin test pin and
exercise extreme caution to avoid
short-circuiting the equipment.
The various supply voltages
delivered by the DC/DC converter
can be measured at the following
points.
M 1: 15 V ± 5% Input voltage for the DC/DC converter.
M 2: –9.2 V ± 5% Supply voltage for the A/D converter
M 3: +9.2 V ± 5% Supply voltage for the A/D converter
M 4: 5 V ± 5% Supply voltage for the digital PCB
