Mini clamp meter, e.g. for troubleshooting at glow plugs without to take the plugs out.

Mesuring range AC and DC 40-400 A, resolution 0,01 A, accuracy 1,5%

Also for voltage AC + DC, 4 - 600 V, 0.75% accuracy and resistance measurement up to 400 megaOhm, accuracy 0,9 - 5 %

All measuring ranges change/calibrate automaticly !

To show broken plug just check the A range while glow system is on work - e.g. 12V/ 4 cylinder engine needs for all 4 plugs around 80 A - if missing 20 A one plug must be damaged.

With regular clamp meter this troubleshooting can´t be done - the clamps are to wide / glow plug calble is too small to show results.
