產品規格

The GM-145B is a complete digital voltmeter module in a compact package incorporating a dual-slope analog-to-digital converter, a 1V reference and full scale input with sensitivity of 2V.

The use of large-sized and red solid-state light-emitting diode(LED) display makes the module easily readable from distance away. The single 5VDC operation enable the module to be easily operated with a standard voltage regulator(7805 type).

Auto-zeroing is provided by the circuitry, so no adjustment is required. Automatic input polarity indication is available. Over-range is indicated by the flashing "0000" display.

The STROBE, OVER-RANGE, UNDER-RANGE, RUN/HOLD and BUSY lines, enable GM-145B to interface to UART, microprocessors or microcomputer.
