PRODUCT DESCRIPTION
The EM32-1B is a 3 ½ digit 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, and options are selected via jumper links. The module features a round metal
bezel, requiring a 32.5mm (1.28") diameter cut-out. It is secured with the nut provided. Protection from the front
to IP 67 / NEMA 4X standards is achieved by placing the rubber seal between the module and panel during
assembly.

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