Description

Megger MFT1741+ Multifunction Tester

The Megger MFT1741+ Multifunction Tester is suitable for troubleshooting and verifying the installation and safety of industrial, commercial and domestic fixed wiring installations. To this end, it includes all the tests required to complete the necessary electrical certification for these systems. Used in conjunction with the Megger EVCA210-UK Electric Vehicle Charge-Point Adapter, (sold separetely) the user can carry out a full range of tests required for the installation of EV charge points thanks to the 6 mA DC testing feature.

The Megger MFT1741+ is particularly well suited to testing low voltage electrical installations in areas with high electrical noise and for conducting full single- and three-phase insulation testing. As indicated above it is able to conduct single- and three-phase RCD testing between 10mA and 1A.

Loop Impedance Measurement & Confidence Meter

The non-trip loop impedance testing technology also enables loop impedance testing of 10mA type AC and A RCDs. Additionally, non-trip loop impedance technology prevents RCDs influencing the total loop impedance value and increases the speed of testing: non-trip loop impedance tests can be performed in eight seconds. Furthermore, loop impedance tests are accompanied by a Confidence Meter. The meter will indicate the degree of confidence in the accuracy of the loop impedance measurement. This feature is useful as loop impedance values are particularly susceptible to changes in circuit noise. The Confidence Meter is designed to improve reliability; the digital ARC indicates the analytical process, and the measurement is continually monitored and adjusted in reference to the circuit noise. Another function present is its ability to test electric vehicle charge point RCDs; it includes automatic test sequences and a 6mA DC test (requires OPTIONAL accessory) for this purpose.

Measurements are viewable via the large, clear backlit display with a digital/ analogue arc for indicating fluctuating readings and a dual digital readout that displays precise readings and test parameters in parallel. For instance, the dual digital readout will display the output voltage used for the insulation test as well as the resistance value in MΩ. It is also possible to save readings to the tester’s internal memory (capacity for 1000 measurements); these results can be downloaded via Bluetooth.

Accessing the required measurement function and range is easy using the colour coded function controls. In addition to improving the efficiency and ease of testing, these controls also reduce the possibility of selecting the incorrect function or range. This instrument does not include complicated and/or hidden measurement menus.

Furthermore, it features an ambidextrous design with dual TEST and LOCK buttons on either side of the unit, ensuring that it is easy to operate for both right- and left-handed users. Moreover, the Megger MFT1741+ Multifunction Tester offers an automatic test start, removing the need to press the TEST button altogether. This function is particularly useful when holding probes and/or whilst on a ladder.

The Multifunction Tester has also been designed to stand independently; alternatively, it can be hung around the operator’s neck using the included neck strap. It is also equipped with internal rechargeable batteries that have a charge time of under four hours, allowing the user to maximise uptime. It also features a rubber over-mould which provides additional protection in tough environments and has an IP rating of 54 ensuring that it is resistant to dust and water ingress.

Th tester is EN61010 CAT IV safety rated: it is able to withstand accidental misuse and voltage transients. The safety rating also means that it can be connected anywhere within the low voltage network on the single and three-phase system.

Additionally, the tester will provide visual and audible warnings when a hazardous voltage is detected. If the Megger Multifunction Tester detects a live voltage during insulation and continuity tests it will indicate the value of the voltage on the display; should this voltage exceed a safe level the tester will halt testing and issue a warning beep. These features not only protect the user but also work to prolong the longevity of the instrument.

The Megger MFT1741+ Multifunction Tester is a versatile, practical and reliable instrument suitable for measuring a variety of electrical parameters. It can be used for electrical installation and verification applications pertaining to low voltage building wiring, as well as distribution testing scenarios.
