Multifunction testers, or MFTs, are used by a variety of electrical workers when measuring the performance of an electrical installation. As the name implies, they are suitable for an extensive range of tests. These include earth resistance, RCD, continuity, loop, and phase sequence testing, among others.
The information provided by these multifunction testers is crucial to ensure the installation is working correctly and safely. As such, it is essential that the device is properly calibrated so that it operates correctly within the manufacturer’s specifications. That’s where Re-CAL comes in.
