Main functions and features

1、The machine adopts 1024×600 dot matrix 65K color resistance touch screen.

2、High-precision sampling and processing circuit, advanced Fourier harmonic analysis technology, more reliable data.

3、With the function of measuring harmonic content, it can measure single phase or three phase simultaneously.

4、With resistive current base wave peak output function.

5、The instrument has built-in large storage capacity. Can store test data, waveform, harmonics and other large amount of recording information. It can save 200 groups of measurement records in the cycle update mode.

6、The instrument is equipped with a U disk interface, which can store any group of test records (the capacity is limited by the size of U disk).

7、The voltage test line of the instrument is equipped with insurance to prevent misconnection. The voltage and current plug of the instrument has the function of misconnection prevention.

8、The instrument is equipped with a wireless module for wireless voltage acquisition and wireless measurement with the host.

9、The instrument has a high precision real-time clock, which can be calibrated by date and time.

10、The instrument is equipped with a high-speed miniature thermal printer, which can print measurement data (optional). 

11、The instrument has a large capacity lithium battery, which can work continuously for 6 hours.

12、It can be connected to Bluetooth for remote control

Precautions

1. In order to use the instrument safely and correctly, please read the instruction manual carefully. Connect and operate according to this manual.

2. Please enter the correct setting parameters before starting the test.

3. The instrument can only be used for low voltage and small current testing, and all leads must be kept away from high voltage.

5. During the test, it is not allowed to remove the test wire.

6. The memory can store 200 measurement results, the earliest record will be overwritten when more than 200 times, please pay attention to copy or export to U disk in time.

7. The host and wireless collector can work while charging. Please charge once a month to prevent long-term battery shortfall.

8. There is a 100mA fuse on the wires connected to the PT voltage. Do not use other specifications of fuse or wires instead.

9. If the instrument fails, it will not damage the tested product. It is not allowed to start the repair and disassembly without permission by our company. Please contact our after-sales service.
