Measure the insulation resistance :
Measure the insulation resistance with the high voltage insulation
tester. The areas we measure are the same as Dielectric strength
test.
(a) Between Sensing tip ~ Grip portion :
1kV (The detector has to be stretched) The insulation resistance
has to be more than 2000 M
W
.
(b) Between Sensing tip ~ Nameplate portion :
1kV The insulation resistance has to be more than 2000 M
W
.
Construction :
Waterproof (detecting head impervious to water).
Leakage Current :
Put high voltage on the parts listed below :
(a) Between Sensing tip ~ Grip portion : 50kV AC, 1 min
(The detector has to be stretched) The leakage current has to
be 100 uA or less than 100 uA.
(b) Between Sensing tip ~ Nameplate portion : 4kV AC, 1min
The leakage current has to be 100 uA or less than 100 uA.
Working temperature range :
-10ºC ~ +50ºC
Battery :
2 button-cells Lr44 (1.5V)
CONSTRUCTION
Front Metal :
To be put in contact with wires, etc for voltage detection.
Test switch :
For checking to see that internal electronic circuit is in order.
Nameplate portion :
For L.V. detection, this portion is to be held by hand.
Grip portion :
Don’t touch any portion other than this during H.V. detection.
