Main functions and features
1. The device is composed of a single-phase AC voltage standard source, a current standard source, a DC voltage standard source, and a current standard source.
2. With calibration function, it can correct the output value of the standard source according to the displayed value of the external standard.
3. The clamp-on ammeter can be tested through the specially designed terminal button and the specially equipped "clamp-on-meter check coil", up to 1000A.
4. It can manually and semi-automatically test the digital multimeters, pointer multimeters, clamp-on ammeters, and installation digital meters of class 0.2 and below.
Includes digital meters with DC analog output.
5. It can generate distortion waves containing 2 to 31 harmonics. The number, order, amplitude and phase of the harmonics to the fundamental wave can be controlled by program.
6. Equipped with RS-232 interface or USB interface and large-capacity non-volatile memory, which can store the test data of 500 pieces of tested meters.
Through the upper computer software, the device can be controlled by the PC to perform automatic and manual inspections, and process and manage the results.
