300V 100A Digital DC Voltmeter Ammeter Power Meter Battery Tester Multi Function Power Meter

Note If measuring below 7 8V needs an external voltage of 4 30V If the voltage exceeds 30V the product will be burnt out Although the DC voltage meter has reverse connection or short circuit protection but there is no protection in the independent power supply it is directly power supply to the device if connect high voltage will burn motherboard and display will not show Feature Can test voltage range 0 300V current range 0 100A test power even up to 30 000W high voltage rechargeable batteries or low voltage 18650 battery Support current voltage capacity accumulation power accumulation power impedance temperature time eight data screen display Product parameters Input Interface Output Interface 100A large current copper nose clip lineVoltage measurement range 0 00V 300V Resolution Accuracy 0 05VCurrent measurement range 0 00A 100A Resolution Accuracy 0 05AAccumulated capacity range 0 999 999Ah Resolution accuracy 0 01AhCumulative power range 0 9999 99Wh Resolution accuracy 0 01WhPower measurement range 000 00 9999 99 W Resolution accuracy 0 01WImpedance measurement range 1 99 9 European resolution accuracy 0 01 EuropeTemperature measurement range 0 99 degrees Celsius 0 99 ℃ Resolution accuracy 1 degree CelsiusTime maximum time 999 hours 59 minutes and 59 seconds Resolution accuracy 1 secondTimer measurement reminder settings countdown 24 hours any settingSmall current standby threshold reminder parameters 2W 0 5 hoursS
