The C.Scope MXT4 Transmitter is designed for use alongside an MXL4 Locator. It enables a far more flexible approach to pipe and cable location enabling the operator to accurately detect, pinpoint, trace and identify the widest range of pipes and cables.

The MXT4 Transmitter now has a greater range of transmitting frequencies allowing improved long distance tracing and utility identification, even on the most congested of sites. A range of frequencies from 512/640Hz up to 131kHz and including the simultaneous dual-frequency 33kHz and 131kHz signal output is ideal for maximising the number of buried services that can be energised and then detected. The MXL4 can apply these frequency signals without direct connection to buried services, using either a Signal Clamp or the simple induction method from ground level, providing a significant improvement in the detection of the smaller diameter or poorly earthed cables.

The MXT4 offers three alternative ways to apply a Signal Generator signal:

Direct Connection allows specific pipes or cables to be individually traced, identified and their depths measured. The use of Signal Clamps, Signal Injectors and Direct Connection leads make this mode the most effective method for pinpointing pipes and cables.

If it is difficult or inconvenient to use Direct Connection, then the Wraparound technique can be utilised to successfully energise a street or car park lighting cable.

Induction allows the Signal Generator to induce a detectable and traceable signal to previously unknown, undetected or inaccessible underground metal pipes or cables.

The MXT4’s fully adjustable One Watt Power Output means that deeper pipes and cables can be effectively energised and then traced over ever longer distances.

It also features a FOUR position power level adjustment so the operator has total control of how much power is in use and when.

A Pulsed or Continuous signal output allows operators to switch to the Pulsed Mode at the push of a button in high interference situations and keep on tracing. The MXT4 has a clear audible signal output to indicate when it is in operation.

A useful in-built audio mute control is also included.

To compliment and support in-built data logging on the MXL4 Locator, the MXT4 Transmitter also has full data logging capability. A years worth of data can be stored, in normal usage, on both the Locator and Transmitter. This can be conveniently transferred at any time via a USB cable to a PC for analysis.

The MXT4 Transmitters do not require periodic recalibration. A fully Automatic Daily Self Test (ADST) tests and confirms that they are functioning at their optimum level each day.

The MXT4 Transmitters perform a comprehensive Automatic Daily Self Test (ADST).

At the start of each day of use, a positive Automatic Daily Self Test result gives confirmation to the operator that the kit is working at the optimum level.

The result of this test is recorded and stored on memory within the products in-built data files and can be downloaded onto a PC at any time within the following 12 months*.

These test results can be used to produce a Product Validation Certificate using the C.Scope PC Toolkit. In addition, any results of the Self Test that have been carried out in the last twelve months* are available. The PC Toolkit can also be used to view and print a copy of the original factory Calibration Certificate.

C.Scope authorised Service Centres are also able to provide third-party Test and Calibration Certification should you require it to comply with client or internal requirements.

The MXT4 has a large, clear and easy to read backlit LCD mounted behind a protective polycarbonate lens. The display indicates frequency and functions selected, power level, connection quality and battery condition. It also displays the Automatic Daily Self Test results.

The MXT4s twin wall construction is robust and durable. It also provides IP65 standard protection against dust and water ingress.

The MXT4 Transmitter has a large detachable accessory tray as its base. It can house not only the standard accessories (Direct Connection Leads, Earth Stake, Connection Magnets, 10m Auxiliary Earth Lead) and the Instruction Manual but also many of the optional extras such as Signal Clamps, Sondes and Signal Injectors.
