Digital constant voltage voltmeter, without housing, with 0.36" triple digit LED indicator.
Features
Low power consumption
Wide measurement range of 5-30.0V
Ultra low inrush voltage: red minimum 4.5V, green minimum 4.7V, blue minimum 5.0V. When the power supply voltage is lower than 4.5V, only the brightness is reduced, but it does not affect the measurement accuracy
Protection against polarity reversal
No need for additional power supply, directly use the tested voltage as the power supply, the range is the same as above
Characteristics
Measuring range: 0. 00V - 32.0V
Power supply range
Red DC 4.50 - 32.0V
Green DC 4.70 - 32.0V
Blue DC 5.00 - 30.0V
Max. input voltage: DC 32.0V (input voltage higher than 32V will damage the tester)
Permissible measurement error: 0.1%
When the measurement voltage >= 10.0V, the error is +/- 0.1V
When measurement voltage <= 9.99V, the error is +/- 0.02V
Input resistance: >100 kOhm
Operating current:
Red: <23mA
Green: <18mA
Blue: <13mA
Refresh rate: about 300ms
Display method: LED dial 0.36 inch
Cable length: 15cm
Dimensions: 23 x 15 x 10mm
