- Working Error: The working error test can be completed in real time during the charging process through the pulse method or the accumulated electric energy method. It supports two methods of testing using new energy vehicles as loads or programmable resistive loads

Test Method 1: Test with new energy vehicles as load

- Test Method 2: Test with programmable resistive load as load

- Clock verification: It has time verification function, real-time clock display, and clock time error test of the charger.
