Review on Functional Multimeter Capacity Temperature Detector by Steven Jackson

It would be helpful if the seller or manufacturer provided something reasonable, but I won't hold my breath. There is a nice box with built in foam to store the counter. He did not reset the current readings. when resetting during a power failure. I returned it. These are the instructions decoded and checked for correctness: __________________________________________________________________________________________ Complete the connection according to figure 2 above. Under the condition of constant power supply and load, replace another data cable. The current shown on the USB tester is larger, the data cable is better, and the charging speed is faster. Tips: When the ambient temperature changes or external heat conduction to the tester causes the current not to return to zero and the display shows 0.01A or 0.02A or something else, please press and hold the button and plug it then into the USB charger current environment current zero calibration temperature, after zero calibration, more accurate measurements can be made. And with zero calibration, the output can not consume load current, so the USB tester shows 0.00A. Operation introduction: (1) Long press in the main interface means power, the time will reset and reset (Wh. 00:00:00 ). )(2)Double click means the power is reset and reset to zero (Wh)(3)Triple click means the time is reset and reset to zero (00:00:00)(4) Without holding the button down , do not push into current, current is the current ambient temperature, the current zero calibration (when the ambient temperature or external thermal conductivity changes in the U table, the current is not zero, zero calibration by this method, zero calibration, the output must not pull a load Current to avoid zero error) (5) When entering the background, short press the switch calibration interface, double-click to start calibration. Accuracy of resolution: 0.01 A Total power range: 0.999999 MWh Accuracy of resolution: 0.001 Wh Power measurement range: 0.299.999 W Accuracy of resolution: 0.001 W Maximum synchronization time: 999 h 59 m 59 s Accuracy of resolution: 1 s Update time: > 500 ms /ty me > 500 ms/time Measuring speed: 0.5 times/s Operating temperature: - 10 + 60 °C Product size: 65 x 24 x 14 mm Operating humidity: 10 80 (no doubt) Due to current flow: < 0.015 A Working pressure: 80 106 kPa
