 Model: 285 HD
|
| Three different ranges of identification of AC voltage : |
285-A HID : 3 ~ 7kV
|
| 285-B HD : 6.6 ~ 11kV |
| 285-C HD : 10 ~ 22kV |
| The LCD will "flash continuously" for high voltage testing. |
| Physical contact with electrical conductors is not necessary when testing for live wires. |
| The 285 HD senses the radiated field that surrounds live conductors. |
| Radiated field strength increases with voltage and decreases quickly with distance. |
| Large LCD display. |
| Continuous monitoring. |
| Easy to install. |
| No batteries required. |
| Weight : Approx. 80g |
