Features

This low cost, compact indicator is ideally suited for low or high volume applications. The meter features a 17 segment LCD to display 0-1V or -1V-0-1V d.c. full scale reading. Other voltages and currents can be indicated via the addition of 2 external 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. The module is mounted into the panel, using the supplied clip. A rubber seal is included, providing splashproof protection for the unit when fitted to the meter during installation. This is a popular part, normally stocked in high quantity and suitable for new designs.
