HT Marcotest MT300 Advanced Multidunction installation Tester

Advanced multifunction device for verification of electric safety of private and industrial electric systems

(IEC/EN61557-1)

 

All verifications of electric safety provided for by standards IEC/EN61557-1.

Advanced Loop Verification of magnetothermal protections, fuses and cable sizes.

Earth resistance by voltammetric method with 2 or 3 spots in TT, TN and IT systems, overall earth resistance measurement and with clamp meter T2100 (optional).

Ground resistivity.Measurement of electric parameters insingle-phase installations (V,A, W, VAR, VA, PF)

Test of RCDs type A, AC, B up to 1A, also with separate clamp jaws with test current up to 10A (with optional accessory RCDX10).

Measurement of insulation resistance.Measurement of continuity of protection conductors.

Verification of phase sequence (SEQ) and leakage currents.

 

Macrotest MT300 is a revolutionary device. Its TFT colour display with capacitive touch-screen allows using this device in a completely new manner. Macrotest MT300 makes available on its display all possible variables to obtain a perfect measurement; your task will only be to “touch” what you really want to measure: then simply leave the rest to Macrotest G3’s micro-processor!

 

The device complies with all requirements as regards the safety of electric systems: test of RCDs type A, AC also up to 1000 mA and type B; insulation, continuity, earth resistance tests (this also with the aid of the optional clamp T2100).

 

With the appropriate programming guided by the touch-screen system, this device can test the interruption power, tripping currents, I2t relevant to magneto-thermal switches (MCB) with curves B, C, D, K and fuses type gG and aM! The device can be used with external feelers for measuring environmental parameters such as air temperature/humidity, illuminance (Lux) further to measuring leakage currents, cosphi, power and harmonics, Loop/Line impedance and calculating the assumed short-circuit current with high resolution (0.1mOhm) in TN systems with use of optional accessory IMP57. Cutting-edge management of measurementwith indication, at the end of each safety test, of compliance or non-compliance with requirements with simple symbols OK or NOT OK.
