Note : |
|
|
|
|
|
1 |
Power mode is used to locate all live cables with sufficient current flow |
|
2 |
Radio mode is used to locate any metallic service carrying a (VLF) very low frequency signal |
|
|
The 250 has a specifically strong radio mode signal which makes it a very popular model |
|
3 |
If the Metallic Pipe has a Current then the 150 can detect it in Power Passive mode |
|
4 |
Active mode is used in conjunction with the Transmitter to locate and trace a specific service. |
|
|
The Transmitter is an Optional Accessory |
|
5 |
The 950 has a large range of Transmitter frequencies which is used when cables are congested and there is a chance of "bleeding" ie current jumping from one cable to another |
|
6 |
Beacon Mode is used for Non Metallic pipes where you create a signal by inserting the beacon / sonde into the non metallic pipe eg asbestos, PVC or plastic The beacon is an optional accessory and needs to be purchased separately |
