General Insulation Resistance Test.

Technical Specifications:

Models:

Scale Length
Approximately 70 mm
Rotational Speed of Handle
160 rpm. and above
Response time
Less than 3 seconds when a resistance, the value of which corresponds to the central scale mark, is suddenly inserted between measuring terminals.
Limits of error
The insulation resistance measurement is accurate to within ± 5% of the indicated value at the Scale mark of the rated resistance, in conformity with IS:2992-1987 stipulations.
Tolerance on Voltage
Within ± 10 of the rated voltage for scale mark of infinity & more than 90% of the rated voltage for the central scale marks.
Accuracy of Voltage
The testers are provided mainly to determine whether the equipment under test is live or not, and not for any accurate measurement work. However the accuracy is within ± 10% F.S.D.
Tilt influence
Less than 0.5mm deflection from the infinity scale mark, due to an inclination of 5 degrees from the horizontal.
Ambient temp. influence
The deviation in indication is less that ± 5% near the central scale mark for an ambient temperature change of 20 degrees from 27 Degree C.
Insulation resistance
1) More than 25 Mohm between the electric circuits and case for rated voltage upto and including 250V. 2) More than 50 Mohm between the electric circuits and case for rated voltage above 250V.
Dielectric strength
Withstands application of 2000 volts AC(rms) for 1 minute between the electric circuits & the case.
