Description
Feature: Dimensions:48mm x 29mm x 21mm Measure voltage: DC 0-30.000V Power Supply: DC 5-30V Input Polarity: DC voltage Refresh rate: 5 times per second Measurement precision: +/- (0.3 ‰ + 2 digit) Display: five 0.36" digital LED Tube Display Color: Red Operating temperature: -10°c to 65°c Temperature coefficient: less than 25PPM /°c Note: The voltmeter needs isolated power supply. Power supply range is DC 3.5-30 V. when black wire and red wire are switched to with the power supply, the voltmeter will display 0.000 (when the measuring line is dangling ,the voltmeter will display one or two base) . Yellow wire and black wire will be switched to the measurement circuit. The measured voltage range is DC 0-33.000 V. Wiring: Red: Power Supply +(DC 5-30V) Black: Power Supply -, Measure - Green: Measure + Package Includes: 1x Digital LED Voltmeter
Features
