General information
It is a multifunctional tool specially designed for analyzing
current transformers and voltage transformers of protection or
measurement use. Which is suitable for all types of CT and PT. It
is suitable for laboratory and on-site test.
Features
1. Finish all testing subject by itself, no need to connect
auxiliary equipment.
2. Built-in printer, to print results easily.
3. Large screen LCD, graphically display.
4. Auto display excitation inflexion point value, 5% and *0% error
curve.
5. Save ***0 groups data.
6. With USB port. The data can be saved in USB disk and read by
PC(WORD format file).
7. Portable design, suitable for on-site test.

Working condition
1. Input voltage: **0VAC±*0%,
2. Rated frequency: *0Hz
3. The analyzer should be supplied by power supply socket which
have ground protection. If ground protection connection is not good
or power supply is not isolation connection with ground, the
analyzer can still work but security can not be assured.
4. Environmental temperature is *3℃±5℃.
5. The assured value is valid within one year after factory
calibration.
