INSTRUCTIONS
OVERVIEW
The X-32 Digital Panel Meter is a unipolar,
three-digit, fixed-range, DC voltmeter. It
features auto zeroing, eliminating zero drift.
The X-32 is a short depth meter of which
requires only one-half inch to mount behind
panel. Calibration at full-scale can be
accomplished by adjusting
potentiometer accessible from the front of
the meter.
A mating connector option provides plug-in
connections of the external leads.
connector, if required, must be ordered
separately. (Part number 53-106).
The X-32 is built to a standard 1 volt range,
yet is also available in five other ranges.
(Select 100 mV, 10 V, 100 V or 1000 V
range) The factory can make this range
modification, or, you can accomplish this
range change by purchasing the range
change kit. (Part number 53-107)
A current measurement option is available,
permitting measurement of DC current from
100 nano amperes full scale (F.S.) to 1
amperes full scale (F.S.).

An external +5Vdc regulated power supply
is recommended for operation. A typical
configuration for a suitable power supply is:

INSTALLATION
1. Mount the X-32 as follows:
a. Cut hole in panel 3.622" (92mm)
W x 1.693": (43mm) H.
b. Insert meter from the front,
through panel cutout.
c. Fit mounting clips (2) into slots
located on top and bottom of
meter. The foot of the clip should
face forward.
d. Thread screws (2) into clips &
tighten screws against rear
surface of panel.
2. If you have purchased the mating
connector option (NLS P/N 53-106),
install a keying tab in the connector
(Position 2) and attach the hookup
wire to the individual connector
sockets. Insert the sockets into the
connector block making sure the
keying tab and sockets are in the
proper position to latch into the
rectangular holes on the block.
(Refer to Table 1). Positions 3, 4,
and 8 do not have sockets.
