Communication underground line digital pipe & cable locator

Key Features:

1. Use of advanced signal processing technology, and the latest integrated circuit components to achieve high test performance
2. a variety of measuring signals transmit mode:Meeting different measurement frequencies:
   1. Injection: injection point for a pipeline.
   2. Induction: for no injection point and can not use the clamp when the pipeline.
   3. Clamp: exposed for a period of pipeline under test, easy to clamp the pipe clamp
3. Users can choose from 480Hz, 31KHz frequencies according to the actual situation; users also can customize measurement frequencies for special requirement (must stated in the order).
4. Different mode and function to improve test effiency:
   1. Peak mode: positioning route by measuring the max value of the signal
   2. Valley mode: positioning route by measuring the minimum value of the signal
   3. Route orientation: quickly and intuitively determine the route direction
   4. Current measurement (CM): detect the target pipeline by measuring the signal of the current
   5. Stethoscope: identify the loaded pipeline by anscultating
5. Subsidiary function:
   1. Receive gain adjust: adjust the gain of the receiver in order to optimize the receiver in the state, replacing the cumbersome manual adjustment of children
   2. Sound features: pitch change in the receiver by measuring the signal directly reflects the size of
   3. Pipeline state detection: when transmitter is injected mode , firstly test the insulation resistance of the pipeline, residual valtage, then apply the signal to the target; When the pipe insulation resistance is low (almost short-circuit ) a transmitter will quit the mode automaticly, transmitter alarms when the residual voltage is high, so the operators shall immediately stop the
   4. Battery tests:   Real-time testing of battery, it will alarm and automatically shut down when battery power is lower than the protection value

Stethoscope and clamp functions: it is used for precisely locating the pipeline in the complex situation (SAT-20C unique function)
