YB21 Voltmeter 0-10V 0-30V 0-100V 0-300V 0-600V Mini Voltage Meter 3-Wire 0.36'' Digital LED Volt Panel Meter Volt Tester
Attention:
The power supply voltage of the instrument should not exceed 30V, and enough safety voltage space should be reserved;
Due to the limited space of the sticker, some infrequent ranges will be manually rewritten on the sticker, please do not order if you mind it.
DC0- 100V, DC0-300V: When the measured value is less than 9.9V, only two digits will be displayed; when the measured value is greater than 9.9V, only three digits will be displayed.
DC0-600V: When the measured value is less than 99V, only two digits are displayed; when the measured value is greater than 99V, only three digits are displayed.
