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).

* To ensure maximum accuracy, re-calibrate periodically.

** Operation of the meter beyond the maximum supply voltage rating may cause permanent damage to the meter.

Unless otherwise noted, specifications apply at T =25°C, V =5Vd.c. (f =48kHz) and are tested with the module configured for floating input

mode.
