| Telescopic, compact, light-weight : Length : from 230mm to 880mm. Weight : Approx. 155g |
| High-voltage detectable : The equipment, whether in stretched state is available for voltage detection in high-tension circuits (3.3kV, 6.6kV and 24kV) whether the wires involved are naked or insulated. |
| Low-voltage detectable : The equipment can be used for voltage detection in low-tension circuits (80V ~ 600V) by holding the nameplate portion of the detecting head. Before-use check can easily be done by plugging in an AC 100V plug socket, without using a tester. |
| Easy to recognize indication : Intermittent lighting in red of a high intensity light-emitting diode and intermittent audible sound of an electronic buzzer are readily recongnizable at a full daylight, noisy location. |
| Waterproof : The detecting head, being tightly enclosed, is free from any trouble due to dust, dirt, water or the like. |
| Dielectric strength : |
| (a) Between Sensing tip ~ Grip portion : 50kVAC, 1 min (The detector has to be stretched). |
| (b) Between Sensing tip ~ Nameplate portion : 4kV AC, 1 min. |
| Construction : Waterproof (detecting head impervious to water). |
| 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 2000M Ohm. |
| (b) Between Sensing tip ~ Nameplate portion : 1kV. The insulation resistance has to be more than 2000M Ohm. |
| Leakage current test : 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 100uA or less than 100uA. |
| (b) Between Sensing tip ~ Nameplate portion : 4kV AC, 1 min. The leakage current has to be 100uA or less than 100uA |
