low impedance 400 Omhs function on AMPROBE AM-550

Question asked by frenchconnection67 on Jul 24, 2015
hi there,

just bought meself an amprobe am 550 and tested it quickly last night. I love it it s so functional and especially that non contact voltage detector function which will deffo make my life easier at work.

there s only one function that I could not figure out how to use, it is the low impedance 400 Ohms which is used to detect straight voltages (ghost voltage) within an installation.

the manual does not mention it but only in the outlines of the possible features and not in details.

and when I press the buton, it beeps, the icon appears but disappaer as soon as I release the button. I tried to keep pressing when measuring but its not working. any idea guys?
