MFT1835 Megger multi-function tester - Megger

Designed for measuring and testing all parameters of low-voltage networks and electrical installations (wiring, RCD, grounding, etc.) with voltage up to 1 kV.

Meter of electrical safety parameters of installations MFT 1835 , manufactured by Megger (England), is designed for measuring and testing parameters of electrical installations (wiring, RCD, grounding, etc.) with voltages up to 1000 V.

The MFT 1835 allows you to test insulation voltages of 100V, 250V, 500V and 1000V with resistance measurements ranging from 10kΩ to 999MΩ. The integrity of the circuit is determined at a current of 200mA and 15mA.

The MFT1835 meter also tests RCDs with ratings of 10mA, 30 mA, 100 mA, 300 mA, 500 mA, 1000 mA. Testing is carried out with current: ½ x I, 1 x I, 2 x I and 5 x I in position 0? and 180.

The MFT 1835 loop parameters are measured two-wire method. 2-wire testing of electrical circuits is performed using only two test leads, measurements - Phase - Ground / Phase - Zero / Phase - Phase. A third wire, which could cause confusion in identifying the part of the circuit under test, is not needed. Measurements take place in the voltage range from 28V to 280V AC in single-phase circuits and up to 480 in three-phase circuits. Short circuit current (SC) is calculated up to 20kA using the measured voltage and loop resistance.

The MFT 1835 device measures alternating voltage up to 600V, allows you to measure frequency in the range from 15Hz to 400Hz and determine the phase sequence.

The resistance of grounding devices is measured using a 2- and 3-wire circuit using the pin method. Currents 0.45 mA or 4.5 mA, resistance resolution 0.01 ohm, noise rejection 20 V peak-to-peak.

The MFT1835 meter has a large LCD display with digital display and imitation of an analog scale. Selecting test or measurement mode is simple and convenient, and is also separated by color gradation. Much attention is paid to testing safety; if the electrical installation being tested is energized, the operator will be notified about this, and the device will not fail (within the CATIV standard).

The MFT1835 device has an internal memory and can save all test data and also transfer it to a PC via Bluetooth.

MFT 1835 M egger is made in a shock-resistant, moisture-dust-proof housing (IP 54).
