Key Technical Specifications

What Makes the MFT1741 a Game Changer?

1. Confidence Meter™ Technology

One of the most frequent challenges during loop testing is electrical “noise” that can lead to inconsistent readings. The MFT1741 uses the patented Confidence Meter™. It monitors the loop measurement in real-time, letting you know exactly when the reading is stable and accurate. No more re-testing just to be sure!

2. Bluetooth and CertSuite Integration

Documentation is often the most time-consuming part of an inspector’s day. The MFT1741 features Bluetooth connectivity that pairs directly with the CertSuite™ app. You can transfer test results instantly to your mobile device, generating professional reports on the go and eliminating manual paperwork.

3. Built for Tough Environments

The device is IP54 rated, meaning it is protected against dust and water spray. With a rugged, durable case, it is built to survive the day-to-day wear and tear of a busy electrician’s toolbox.

Common Challenges in Installation Testing

Unstable Loop Readings

If you are getting erratic values during a loop test, it is often due to external interference or unstable connections. The MFT1741’s Confidence Meter™ will alert you to this instability, allowing you to re-check your connections rather than recording false data.

Inaccurate RCD Tripping Times

If RCDs are not tripping within the expected time, check for excessive leakage current in the circuit. The MFT1741 allows you to perform highly precise RCD testing, including Type B RCDs, which are critical for modern EV charger installations.
