PROTOMETER PN: DLP-PMV Perfect for use Low-Cost, on solderless breadboards Hands-Free Voltmeter The PROTOMETER Voltmeter was designed to take up as little space as possible on your workbench, thereby reducing clutter and freeing your hands from holding test leads. The extreme low-power design and auto- power-off feature ensure that the coin-cell battery will last for months. The easy-to-read LCD display will present positive and negative voltage readings without having to reverse the connection to the circuit under test. DC measurements are performed by a simple average, and AC measurements by an RMS calculation. Measurement Range: 60 Volts DC Max, AC (RMS) 60V Max Basic Accuracy: 2% AC, DC Primary Power Source: One CR2032 Coin-Cell Battery TTL Serial Output: 0-3V Output, 9600 Baud N81, ASCII with CR/LF External 5V Power: External 5V Max Supply (Purchased Separately) Shown here with an optional USB cable (purchased separately) for connection to a host PC. The USB port can be used Lightweight design allows for both data logging and operational the PROTOMETER to Coin-Cell Powered power. The DLP-PMV has an on-board hold itself upright using 3V regulator for use with an optional only the two test pins. external 5V (max) power supply.
