EMA 1710 9 Segment LCD Meter

This low cost, compactindicatorisideally suited for low or highvolumeapplications. The meter features a9segmentLCD to display 1V d.c.
full scale reading. Other voltagesand currents can be measuredviatheadditionof2 scaling resistors. The metercanbeusedinapplications
where the orderofmagnitude of the reading ismoreimportant than the value ofthereading itself. It allows theoperatorto scan the display
and receive a quick visual feedback. Installation is particularly easy; the module requires only a single round hole in the panel. A rubber
seal is included, providing splashproof protection for the unit when fittedtothemeterduringinstallation.

PANELFITTING

Drill a5.5mm / " holein the panel. Fit seal tothe rear ofthe module. Fit the module to the panel by passing its screw threaded studand the wiresthrough the
hole, fitting the washer and tightening the nut. Take care not to trap any of the connecting wires. Do not to overtighten the nut as this may damage the meter.
