5. With timing function, remind users to record, and analyze absorptance
and polarization index of measured target.
6. High quality: The key parts are all imported components, to ensure
accuracy and accurate.
7. Easy to use: one-piece chassis, small size, light weight, easy to carry.
8. Look beautiful: rugged and strong grinding material, the instrument's
overall texture and longer life.

Note:
(1) Calibration voltage of MΩ range is 0.5kV, GΩ range is 2.5kV.
(2) Ensure the accuracy of resistance measurement test voltage range:
more than 20% of the nominal value of the voltage range.
(3) When the test voltage is higher than 8kV, for the accurate
measurement of higher 20GΩ resistance, high voltage electrode conductor
exposed to the air shield should be added to avoid the impact of air ionization.
(4) 2000 GΩ range is the reference range, its application environment:
relative humidity< 70%.
5. Anti-electric field interference ability: 2mA (50/60Hz).
