GENERAL DESCRIPTION
PAX Lite Current and Volt Meters are premium quality instruments designed
for tough industrial applications. With multi-range capability, built-in provision
for scaling, and DIP switch selectable decimal points, these meters offer the
ultimate in application flexibility. Four models cover your voltage and current
indicator needs. The meter can provide direct readout from pressure, speed or
flow transducers, or any other variable that can be translated to voltage or
current. The built-in scaling allows the display to be scaled to the desired
engineering unit.
The 3 ½ -digit bi-polar display (minus sign displayed when current or voltage
is negative) features a 0.56" high, 7-segment LEDs for easy reading. The meter
is also available with custom units label capability. Using the PAX label kit
(PAXLBK30), the selected label is installed behind the panel, keeping it safe
from washdown or other environmental conditions. A DIP switch is used to
control the backlight for the units label.
The meters have a NEMA 4X/IP65 sealed bezel and extensive testing of
noise effects to CE requirements, allowing the meter to provide a tough yet
reliable application solution.
CAUTION: Risk of Danger.
Read complete instructions prior to
installation and operation of the unit.
DIMENSIONS In inches (mm)
CAUTION: Risk of electric shock.
Note: Recommended minimum clearance (behind the panel) for mounting clip installation is
2.1" (53.4) H x 5.0" (127) W.
