If the fuse is blown you get a consistent reading of about 1 per cent of
the
true reading.



That isn't anything like is going on here. If I set it to read low ohms for
example, it starts out at around 300 ohms, then ticks down steadily until
after a few seconds the continuity beeper activates and then it keeps going
down to -0.00. If I set it to the regular ohms range, the bargraph ticks
rapidly. AC volts reads a few millivolts regardless, haven't tried DC volts
yet.
