DC 0-100V 3-Wire Mini Red LED 3-Digit Volt Voltage Panel Meter Voltmeter [a13061700ux0113]
Date Added: Wednesday 25 June, 2014
Accurate voltmeter with value-for-money specifications.
Measured accurate to within +/- 0.1 Volts. In case a little off the mark easily adjustable with a tiny trim pot on the back.
Due to its size very usefull in limited space applications.
Brightness is sufficient (acccept in direct sunlight) and not blinding.
When all digits in use (88.8 volt) a measured maximum of 14 milliamp is drawn.
Wiring is a bit short (20 cm.) but easely adjusted to requirement by replacing the wiring since all three wires are connected with one connector (some other panel
meters have only a two-wire connector for the power and a seperate direct connected wire for measuring).
Handy for both 4-30 volt (red+white on +, black on -) and 0-99.9 volt (red on + powersupply 4-30 volt, white for measuring, black on shared -) measuring.
Red always needs _ 4 volt for correct working of voltmeter.
