Product Description

Megger MFT1741 18th Edition Multifunction Tester

The MFT1741 multifunction tester has been designed for testing single and three phase low voltage domestic, commercial and industrial electrical installations, providing all the tests required to complete the necessary electrical certification. All with an EN61010 Cat IV safety rating too.

Built to last and take the strains of everyday testing, the 1741 is robust, featuring a large central back lit screen with test buttons situated either side for accessibility for both right and left handed users. Smooth single click rotary dials and large buttons make for easy operation even when wearing gloves. The unit is also IP54 rated, perfect for dusty environments and for the often unpredictable British weather!

The Megger 1741’s new 3 wire loop impedance test uses a combination of test currents and measurement methods to eliminate RCD impedance uplift.

Overlaying the new non-trip loop impedance measurement is the new “confidence meter”. As loop impedance values can be dramatically affected by circuit noise, the Confidence Meter displays the degree of confidence in the accuracy of the measured loop impedance via an expanding and contracting arc.

How does the confidence meter arc work?

Circuits with low / no noise.

The display shows a full width analogue arc, consisting of 51 elements. At the start of the test all elements are displayed. The instrument will then check for any adverse electrical noise. If nothing is found the test sequence will terminate and display a final value. The arc closes to one centre element, indicating the maximum degree of confidence in the result.

Circuits with high noise / distortion.

On detecting noise on the supply the Confidence Meter will continue testing and refining its measurement. This is shown by the noise symbol to the left of the display appearing and the arc closing more slowly, pausing or even opening up again in high noise situations. When the confidence meter has refined its measurement, the arc will finally close to one element and the test will stop. The final displayed result may differ from the original quite significantly.

Extreme noise may cause the loop test measurement to continue for over a minute. In this case the tester will stop automatically and the size of the arc will indicate how good the meter believes the displayed value is.

The 1741 also protects against accidental misuse, giving both visual and audible warnings if the unit detects voltages exist on the circuit. Testing will be inhibited to prevent serious damage. Also, save money on batteries as the 1741 includes rechargeable batteries and charger, with a charge time of less than 4 hours.

Answers:

Posted by Ben Masters on Tuesday, 30 April 2019

The accessory required is the 3-wire earth electrode test set (part no. 1001-810). This also works with the other MFTs in the Megger 1710 range.

I've seen that it doesn't trip rcds and rcbos? Is this on all types?

The MFT1741 will trip 30mA type B RCDs and RCBOs. Other than that, the unit is non-trip on all other RCDs and RCBOs
