Does the DROK Digital Multimeter DC 6.5-100V 100A Voltage Amperage Power Energy Meter DC Volt Amp Tester Watt Meter LCD Digital Display, PN B017BDQHE6, reverse the energy used (Wh) number when the batteries are charged after being used? For example, if the display is showing Energy = 100Wh, if you were to charge the battery would this number return to 0Wh after being fully charged?
