DC INPUT (load input terminal on the rear
pane!)
Terminals used to connect the equipment under test
to the
PLZ-U.
The terminal
is
connected in parallel with the load input terminal
on the front
panel.
•
For
the connection procedure, see section
2.8.2, “Connection
to the Load Input
Terminal on the Rear Panel.”

+S and -S (remote
sensing
terminals on the
rear
panel)
Terminals used to
connect
the
sensing wires
when
correcting the voltage
drop
caused
by the resistance of the load wire. The remote sensing
terminals are
located
on the front and rear panels, and they are connected in parallel
inside the PLZ-U.

Air outlet
Exhausts the internal air using the cooling fan
to cool the
inside
of the PLZ-U. The
speed
of
the cooling fan increases according to the internal temperature.

Manufacturing number (serial No.)
Manufacturing number of the frame.
[5]
AC INPUT
Connector used to connect the power
cord.
[6]
GPIB
A connector used to connect the GPIB cable when controlling
the PLZ-U via
GPIB.
[7]
RS-232C
A connector used to connect the RS-232C cable when controlling the PLZ-U via the
RS-232C.
[8]
FRAME CONT1 and 2
Connectors used to externally control the load on/off, memory recall, and other
functions simultaneously on all channels.
[9]
CHCONT1,2,
3(4,
5)
Connectors used to
externally
control the load on/off and
f^rform
external
control
using external voltage reference
on each
channel.
The connector also
provides cur-
rent monitor
output and power
supply
output
for the controller.
[10]
Strip gauge
Strip gauge for the screwless terminals used on the CH CONT
connectors and sens-
ing terminals on the front panel.
