99v led

Description: • This instrument adopts imported LV321 current operation amplifying IC, which provides 140 times of amplification factor and adopts 5 milliohm current sampling resistor, so it is more accurate than 50 milliohms of the same industry. • The small energy can stably display 1mA current, the small current range within 1A, the measurement error is less than 0.5mA, and the 4A high current range is less than 1%. Features: ?ﾺPower-Off storage technology. When testing the capacity, such as an unexpected power failure, when the voltage drops to 2.2V, the internal storage circuit is triggered instantaneously, and the capacity stored in the battery is saved. ?ﾺThe leading 5 ohm current sampling resistor, with smaller line loss, means that the Dynamic current can be measured more accurately by a larger current. ?ﾺQuickly read valid data in a short period of time, IC Resolution 0.1mA ?ﾺWhen the input voltage is lower than 4.5V or higher than 5.7V, the light alarm device will be triggered. (Measured iPhon'e is higher than 5.8V to stop charging) Specification: The measurement voltage range:3.50-26.99V Max current:4.19A. Display:The current is greater than 1A and the display unit is Ampere (A), for example 1.00, which means 1.00A. The 3-digit red LED indicates the USB input voltage in volts (V), for example 5.20V. Intra-range error is less than 1% The 3-digit blue digital tube indicates the USB input current. Less than 1A, the unit is mA, such as display 2, indicating 2mA; display 15: indicating 15mA; The charging test supports the new Qualcomm 12V charger with a large display voltage of 26.99V. Large withstand voltage 32V The overall power consumption does not exceed (25V) 8mA, the normal working current is 6mA, and the small working current is 2mA (turn off the screen display light) Package includes: 1 x USB Voltage Current Tester Detail pictures:
