2. Suitable for measuring in strong electromagnetic interference environment.

3. Wider measuring range, several voltage output gears.

4. Output voltage is continuous and adjustable

5. Auto measure R15, R60, R600, auto calculate DAR, PI

6. Strong load capacity, short-circuit current about 5mA.

7. Measuring range up to 0 ~ 10TΩ, auto switching range.

8. The analog bar pointer & digital display, clear and accurate

9. Test time display at any time, buzzer beeps every 15 seconds

10. Auto discharge high voltage within 30 seconds after test

11. Auto measure ambient temperature, air humidity, date and time.

12. Storage capacity up to 60 records, data may not be lost for 20 years.

13. RS232 serial interface

14. Built-in Micro-printer

15. Auto remind power off when no operation for 5 minutes
