PANEL FITTING
Drill a 5.5mm / " hole in the panel. Fit seal to the rear of the module. Fit the module to the panel by passing its screw threaded stud and the wires through 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.

This low cost, compact indicator is ideally suited for low or high volume applications. The meter features a 9 segment LCD to display 1V d.c.
full scale reading. Other voltages and currents can be measured via the addition of 2 scaling resistors. The meter can be used in applications
where the order of magnitude of the reading is more important than the value of the reading itself. It allows the operator to 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 fitted to the meter during installation.
