Designed from the outset with safety and convenience in mind, the MFT1721 tester provides comprehensive and easily accessed facilities for testing electrical installations in line with the 17th Edition of the IET Wiring Regulations. The MFT1721s are extensively protected against damage if they are accidentally connected to a live supply when a dead circuit test is selected, and this protection is effective even if the test has been locked on.
Other key benefits of MFT instruments include lightweight yet robust IP54 construction, large backlit display panels and timesaving features like two-wire non-trip loop testing, auto-start continuity and loop impedance testing, with full auto-RCD testing.
The TPT320 two-pole testers included free of charge in the kits are an ideal complement for the MFT1721 testers. Compact and fast to use for simple tasks like measuring voltages and checking continuity, they are also essential for proving circuits are dead, as they make connections to the circuit under test with an integral probe and a permanently connected test lead. This means that there is no risk of an accidentally unplugged test lead producing misleading and potentially dangerous results.
The MFT1721 offers insulation testing at 100 V, 250 V 500 V and 1 kV, continuity testing at 200 mA when certifying, but with the option of 15 mA to save batteries, an extensive range of RCD tests including automatic RCD testing, and maximum Zs and R1 + R2 display for circuit verification. The MFT1721 also has a phase rotation feature, and facilities for testing three-phase RCDs. In addition, this keenly priced instrument has provision for measuring voltage, frequency and, when used with a suitable clamp, current.
The kit includes a TPT320 two-pole tester, which has both an LED display and an LCD panel. The LED display provides an instant at-a-glance indication of voltage in six steps, plus, in the case of DC voltages, polarity, while the LCD panel provides a three-digit readout of the voltage being checked.
The tester also incorporates two red LEDs that light when it is connected to voltages high enough to present a shock hazard, and this feature remains fully functional even if the tester’s batteries are missing or completely discharged.
If you would like one of these celebration kits with a FREE two-pole tester worth £79, ask your wholesaler to order part number: 1008-124 any time before the end of January.
