Megger Multifunktionstester MFT1825-CH-DE/FR/IT Electrical tester set

The MFT1800 series includes three instruments for the testing of electrical low-voltage installations. MFT1800 has all the necessary testing capabilities for the mandatory certification of commercial and hardwired home installations:

Test functions and measurement ranges
System voltage and system frequency measurement (true effective value)
Insulation testing with 100 V, 250 V, 500 V and 1000 V with input protection against external voltages up to 600 V even during insulation tests
Constant resistance with 200 mA or 15 mA test current
Automatic - the TEST button does not need to be pressed, both hands remain free
Resistance range 0.01 Ω to 100 kΩ fast continuity buzzer with adjustable thresholds
Loop test without triggering
Earth loop test
Range for two and three-conductor loop resistance test to trigger without FI/RCDs
2-conductor high-current with external conductor to external conductor
Calculation of the possible short circuit current up to 40 kA phase against phase highest resolution

FI/RCD tests include:
Type AC, A, S, B and programmable FI/RCDs
1/2 x I, 1 x I, 2 x I and 5 x I
3-phase FI/RCDs
Quick ramp testing
Automatic testing
Display of fault voltage/contact voltage

Earthing tests
2-pole method,
3-pole method

Safety and device specification
All MFT1800 instruments are specified for CAT IV 300V and therefore for connection to low-voltage systems without protective equipment. They can be safely connected to the transformer at any point in the system, any high transients up to the limits specified in IEC 61010 CAT IV can not damage MFT1800.

Design and usage comfort
Thanks to its modern design, the MFT1800 can be operated on the floor, in the shelf compartment, standing on a platform, with the belt on the body or held in the hand.

With the double test buttons, MFT1800 can be easily controlled with the right or with the left hand.

With the handy, color-coded rotary switches operation is simple and fast, the selection of a wrong function or an incorrect range is avoided.
