   Nominal working temperate range: 18~28ºC

   Reference humidity range:  40%~60%

   Nominal working temperature range:  25%~70%

   Resistance variation limitation:

Influence	Nominal working range	Allowed variation
Environmental Temperature	18~28ºC	a/2 %
Relative Humidity	25%~70%	≤10GΩ a/2 % >10GΩ a%
Working Voltage	(1~1/5)nominal voltage	≤10GΩ a/2 % >10GΩ a%

 

Note: "a" is the accuracy degree of output resistance meter.(a's value is according to different resistance meter)

√ Insulation Resistance:

   The resistance value measured under nominal voltage is no less than 5TΩ, this value is the insulation resistance between output circuit and the circuit without any electric connection.

√  Dielectric strength: Between resistance output circuit with test point, the withstand ability is sine frequency 45~65Hz AC 11kV, test 1 min, no breakdown and flashover.

√  Residual resistance of input terminal should be <0.1Ω, variation <0.01Ω.

√  Oversize: 442mm×270mm×145mm

√  Weight: <5kg
 

Voltage measuring (HV DC Digital Voltmeter):
