Geekcreit® 0.28 Digital Voltmeter Adjustable DC Voltage Meter, Two-wire 2.5-30V / Three-wire 0-100/500V Display

Product Details

• Feature:
• The wiring of this voltmeter is simple. It uses a conventional two-wire system, where the red wire connects to the positive and the black wire connects to the negative. Protection against reverse connection is ensured.
• No external power supply is generally needed. The voltmeter can directly operate with the measuring voltage. The measuring voltage range is 2.50-30V for two-wire and 0-100V for three-wire connections.
• This voltmeter supports wide voltage operation, with a low safe limit of 2.50V and a maximum up to 40V. Voltages exceeding 40V may cause damage.
• When measuring voltages below 10V, two decimal places are displayed. For voltages above 10V, only one decimal place is shown.
