This equipment is the high performance digital measurement equipment to measure the location and the depth of
buried cable / metal pipe from the ground. By adopting the most recent microcomputer technology, the digital
correction of the measurement data realizes stable and high precious measurement.
- Principle measurement method -
When current flows through a buried cable/pipe, an alternating magnetic field is generated around it.
Location, depth, and current value of the buried pipe can be measured using the Receiver at the surface of the ground.
- Feature -
·
Adopting differential coil method makes the Receiver to receive the signal from direct below the Receiver by cutting noise from
surrounding area.
·
Three kinds of the location measurement mode
*All mode: The method to detect maximum and minimum sensitivity simultaneously. The direction and the depth of buried
pipe are continuously displayed. (having error detection protection function)
*Peak mode: The method to detect maximum sensitivity. High precision.( having error detection protection function)
*Null mode: The method to detect minimum sensitivity point being indicated with arrow. (having error detection protection
function)
No switch operation needed. Applied to at deep depth with stable location work.
·
Two kinds of the depth measurement mode
*0-5m (16ft) mode : Measurement of deep depth with high precision is possible at indirect method, the end of cable, and
jointing points.
*0-10m (30ft) mode : Stable measurement is possible at deep depth, near guardrail, or fence.
Do not use this mode with inductive mode.
·
The Receiver itself can measure commercial frequency ( 50 / 60Hz, 100 / 120Hz) and Radio ( from 9k to 33kHz) without the use
of the Transmitter.
·
The best-suited frequency is automatically selected at radio (9k - 33kHz) with
search function
.
·
The measured data is stored (max. 400 data ) with
one-touch
operation.
The data can be transmitted to a PC as standard function.
·
Broadcasting of four frequencies (512Hz, 9.5kHz, 38kHz, 80kHz) as usage meets various buried pipe.
·
A Probe as an option can be used to detect nonmetal pipe.
