Lascar EM32-1 Data Sheet

EM32-1B

Round Hole Mounting LCD Voltmeter

PRODUCT DESCRIPTION

The EM32-1B isa3½digit LCD voltmeter which is designed to be panel mounted in most low and medium
volume applications. The meter features 8mm digit height, 3 decimal points, auto-polarity,auto-zero, 200mV full
scale reading and a very low current consumption. This product is designed so no soldering is required.
Connection is via screw terminals, andoptionsare selected via jumper links. The module features aroundmetal
bezel, requiringa 32.5mm (1.28") diameter cut-out. It is secured with the nut provided. Protection fromthe front
to IP 67 / NEMA 4X standards is achieved by placing the rubber seal between the module and panel during
assembly.

SAFETY

Tocomply with the Low Voltage Directive (LVD 93/68/EEC), input voltages tothemodule’s pins must not exceed
60Vdc. The user must ensure that the incorporation of the panel meter into the user’sequipmentconforms to the
relevant sections of BS EN 61010 (Safety Requirements for Electrical Equipment for Measuring, Control and
Laboratory Use).
