4.8 Control Multimeter
4.8.1 Introduction
This section describes only the inputs to the Control Multimeter.
Since the Control Multimeter is exactly the same as the Drive
Multimeter except for the inputs to the meter, please refer to the
Drive Multimeter section for a more detailed description of the
actual meter circuits.
4.8.2
Location
The Control Multimeter is mounted in the center PA compart-
ment on the upper right hand side (See Fig. 4-10).
4.8.3
Control Multimeter Inputs
Refer to the Control Multimeter schematic diagram for the
following circuit discussion.
The Control Multimeter has eight (8) inputs as follows:
1. A/D Input
2. B+/B- Unregulated
3. +12 VDC
4. A/D Output
5. B- Drive
6. +22/-22(+) and +22/-22(-)
7. +8/-8 VDC
8. Probe Input
With the exception of the A/D input and A/D output positions,
the Control Multimeter is used to monitor the Low Voltage
Supplies to the circuit boards. For more information on the
purpose of these monitor points refer to Section K, A/D Con-
verter board.
