Product Features
1. Fully Automatic Tester
Simply set the maximum output voltage and maximum output current, and the instrument will automatically start from zero to increase voltage or current for various tests. During the test, it automatically records test data, plots the volt-ampere characteristic curve, 10% and 5% error curves, and automatically calculates the inflection point value. This eliminates tedious steps such as manual voltage adjustment, manual recording and organization, and curve plotting, greatly improving test efficiency. Test results can be stored in the instrument, printed on-site or later, or transferred to a computer via USB for processing and printing. The operation is quick, simple, convenient, and easy to master.
2. Comprehensive Functions
The functions of the device are as follows:
CT Test: Volt-ampere characteristic curve PT Test: Volt-ampere characteristic curve

Secondary DC resistance test Secondary DC resistance test
Primary current injection test
3. Output Hold
It has a voltage boost hold function for metering verification and secondary AC withstand voltage tests. It also has a current boost hold function for secondary loop inspection.
4. True RMS Sampling
All voltage and current signals are sampled as true RMS values. Please use a true RMS meter for calibration.
5. Single Power Supply, Easy Operation
Only a single input power supply, AC220V, is required, abandoning the outdated method used by some manufacturers that requires a 380V power supply to meet technical requirements.
6. USB Storage
Test data can be transferred to a PC via USB for processing, display, printing, and storage of data and curve reports, greatly facilitating report organization for users.
7. Date and Clock
The instrument comes with a built-in system time. During tests, the device automatically records the test time for easy storage and review of test records.
8. Non-contact Testing, High Safety
It is a fully computerized device. Once settings are completed, no manual contact is required, and the instrument performs tests fully automatically. This keeps test personnel away from high-voltage circuits, ensuring their safety.
