20MΩ/500V	0.5~19.99 MΩ	±(5%+5digital)
200MΩ/1000V	5.0~199.9 MΩ	±(5%+5digital)
2GΩ	0.05~1.999 GΩ	±(5%+5digital)
20GΩ	0.5~19.99 GΩ	±(5%+5digital)
200GΩ	5.0~199.9 GΩ	±(10%+10digital)
2000GΩ	50~1999 GΩ	±(20%+10digital)

Calibration voltage of GΩ range is 2.5kV

**-- 2000 GΩ range is the reference range, its application environment: relative humidity< 70%.

3. Anti-electric field interference ability: 2mA (50Hz)

4. Timekeeping and alarm functions: maximum value of stopwatch is 19 minutes and 59 seconds. 20 minutes for a cycle. The stopwatch will tell the time at these time points: 15 seconds, 60 seconds and every 60 seconds. When telling time, resistance readings hold for 5 seconds. If the measured resistance is below the lower limit of range, the reading is invalid and the instrument will continuously sound to give an alarm.

5. Display: three and a half bits LCD digital meter (three), respectively show test voltage, test resistance, test time.
