Product function characteristics
2)In this table is three measure and manganese metal copper low rolling-resistance sampling device of wide voltage large current USB watt-hour meter 165 w high power measurement, can be single at the same time monitoring show that the dc voltage, current, power, power, current time of USB equipment, in particular the high-definition LCD and LCM resolution of 128 * 64 = 8190 pixels that shows more clear parameters and built-in welcome boot screen, make the content more rich human, built-in memory can store electricity blackout data such as time, but also through watt-hour meter above keystrokes, you can reset data such as power, time, let the playability is higher, is a production assistant and digital users the ideal equipment
2)Pay attention to high temperature and exposure and metal scratch surface shell, etc.This form USES A low-resistance metal sampling device, 3)current amplification coefficient more accurate multiples as higher requirements to the environment, in order to measure more accurate design is obtained by using the fast refresh, so sometimes will be at ambient temperature changes in light phenomenon of zero zero occasional, if you find the occasional light show 0.01 A or 0.02 A, this is normal phenomenon, can also explain this form because you heat conduction on heat devices such as external charger or load makes small errors in this form of internal temperature change device, this time you light some time let the temperature normal temperature will return to 0.00 A current, if found at room temperature can't restore to 0.00 A, also can reset to zero by oneself, the method is: when no electricity to hold down the key not to put insert
3)This form USES A low-resistance metal sampling device, current amplification coefficient more accurate multiples as higher requirements to the environment, in order to measure more accurate design is obtained by using the fast refresh, so sometimes will be at ambient temperature changes in light phenomenon of zero zero occasional, if you find the occasional light show 0.01 A or 0.02 A, this is normal phenomenon, can also explain this form because you heat conduction on heat devices such as external charger or load makes small errors in this form of internal temperature change device, this time you light some time let the temperature normal temperature will return to 0.00 A current, if found at room temperature can't restore to 0.00 A, also can reset to zero by oneself, the method is: when no electricity to hold down the key not to put insert ?
