There is a 14-position terminal board on the rear panel . See Fig. 2.4. The pins are numbered
from left to right. Pin 1 is the 15 VDC regulated output of the pow er supply. Pin 3 is the -15 VDC
regulated output of the power supply. These terminals can supply up to 150 mA each for use in
external display boards, etc. Pins 2, 4, 6, 8 and 13 are common for both the positive and negative
supplies. All five of these terminals are tied together internally. Pins 7 - 10 are the 0 - 5 VDC flow
output signals from the flowmeters on channels 1 - 4 respectively. All four of the terminals can be
monitored simultaneously. These signals are referenced to pin 13 (flow common) and to the power
supply common terminals.
