TESTER FOR THE SEQUENCE OF PHASES AND ROTATIONS OF THE MASTECH MS5900 ENGINE. parameters: Maximum voltage: 400V AC on all ranges Power supply: 9V 6F22 battery 1 pc. included / current consumption max 20mA Operating temperature: 0C ~ 40C ( 32F ~ 104F) / 15% ~ 80%RH Dimensions / weight: H:27 x W:61 x L:124 [mm] / 150g (including battery) Phase detection nominal voltage: 120 ~ 400V AC Frequency range: 2 ~ 400Hz Frequency range: 2 ~ 400Hz Nominal voltage (Ume): 1 ~ 400V AC Test current: less than 3.5mA/per phase Phase sequence and motor rotation direction tester It has the following functions: - testing the correctness of the three-phase electrical installation - non-contact detection of the direction of rotation of the electric motor - checking the correct connection of the electric motor - detection of the magnetic field of the electric coil The basic function - testing the correctness of the three-phase installation - is performed by connecting the measurement cables A, B, C to the phase wires L1, L2 and L3 and observing the lighting of the LED indicators. From the description table, you can read the direction of phase rotation and the presence/absence of phase voltage L1, L2, L3. If necessary, you can change the direction of rotation by swapping the wires. Included: -Mastech MS5900 phase sequence and engine rotation tester - Crocodile clamps 3 pcs. -Banana test leads - Banana (safe) 3 pcs. - Case with shoulder strap -Manual in Polish -9V 6F22 alkaline battery 1 pc.
