I am interested in your meter but I have to ask
the bleeding obvious. Have you used this
meter to measure direct current recently?
Just for me can you clamp it round the battery
neg. cable of your car battery and get someone
to crank over the engine for you. I just want
to know for sure before bidding that it does
work on DC.
Switch all the lights and accessories on in your
car without the engine running and tell me what
the meter reads compared to a DC ammeter
in your car if there is one.
Just tell me what your "clamp on" meter reads.
With the engine revving and all accessories
switched on, heater fan, rear window demister
and high beam lights what is the reading
when you clamp the meter round the alternator
Sorry for asking you to do this but I have
bought some dud stuff on ebay by being
too trusting and not asking questions.
I had one seller of a mobile phone tell me
when I complained that the phone didn't
work. "You didn't ask me if it worked or not"
Good condition just meant that it looked nice,
whether it worked or not, is something else.
I have learned my lesson and I am asking
you. Please double check the meter on DC
for me by making a few measurements on

** That is not a DC clampmeter - it is AC only.
There is a current transformer with openable core driving a moving iron
meter ( note the scale is cramped below 50 amps ) - so like any
transformer is passes only AC.
DC clampmeters are electronic and use Hall Effect sensors.
