R20.01

* Easy to use 200mV digital panel meter (DPM)
* On-board calibration control
* Automatic polarity indication
* Decimal point selectable
* Very high input impedance - 1000 Mohms
* Very low current consumption - typically 1mA

A compact, low cost digital panel meter which consists of a PCB based module for mounting in existing equipment, behind a front panel or for making a dedicated voltmeter type instrument.

The LCD is 3½ digits with a digit height of 13mm. The input is up to 199.9mV with an accuracy of ±0.5% +1 digit.

The module is capable of performing both digital voltmeter and ammeter functions, depending on how the input is configured with additional resistor chains (examples are shown in the instructions supplied). Applications can include custom power supply monitoring and other specialised voltmeter and ammeter uses. Input power is in the range of 9 to 12V DC. The module measures just 68 x 44mm high and is designed to clip into a panel opening of 54.5 x 38mm.

Important note: The panel meter power OV rail must not be isolated from the input OV rail.
