Metrel MI2120

		MI2120
	Fast testing of all RCD’s (10,30,100,300,500,1000mA) both standard and selective types, AC and A types. Test current multipliers of x 0.5, x 1, x 5 for checking of the trip out time on limit current values. Selectable phase angle 0º (positive), 180º (negative). RCD trip-out current (l∆) measurement with high resolution test ramp. RCD trip out time (t∆ ) measurement at nominal differential current in accordance with the standards. Contact voltage (Uc) measurement for checking of Earthing System LOOP (EARTH) resistance measurement without tripping the RCD. Fast and accurate measurement of: LINE (EARTH) resistance with a test current of 2.5A LOOP resistance with a test current of 2.5A LINE/LINE resistance with a test current of 2.5A.
