    here are the specs for the one i think i need....8-function, 20-range
    multimeter offers true RMS readings for accurate voltage, current and
    temperature. CAT III-600V rating. Audible and visual warnings to help
    improper test lead input. this one does everything the following one
    does except the duty cycle.

    and the one i just bought 11-function, autoranging, AC/DC Voltage/
    current, resistance, capacitance/ frequency, countinuity/ Diode test

    I am going into HVAC-R and I needed to pick up a meter, which one of
    the two would you go with?

    ** You really do not need the " true rms" function for your work - all it
    will do is draw more battery currrent and make it slower for AC readings to
    settle.

    OTOH - having auto-ranging is a wonderful time and frustration saver.

    Instead of 20 plus positions on the switch - you have only maybe 5.

    I'd still take the first one. Duty cycle isn't so important.
    In most meters that are not designed for it, it'll simply display
    peak DC voltage. Some DMM's may miss behave on a pulsing DC signal
    that are not attempting to overcome this..

    In HVAC, the duty cycle option may not be that important.
    You did say the first one had every thing else except the duty cycle
    of the second?

    Have you considered looking into a Fluke 187/189 or 287/289 ?
     
  4. Post details of the brands and models.
    Specs don't mean much, build quality means everything, particularly if
    you are taking it into the field for work. You will want a top quality
    brand.

    Very true. Battery replacement gets to be slightly tiresome with these.
    Especially with Fluke 80 series IME.

    Also true.

    I agree wholeheartedly.

    No it *fucking well won't* you complete MORON ! It's display the AVERAGE DC
    voltage.

    Stop posting garbage about things you don't understand.

    You are an asshole !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
    The meter must be designed to do so .. Some even have a
    duty cycle display for you in the event that it is detecting
    a non 100% duty cycle..
    No, Asshole, Not all meters average on DC..

    Just goes to show how much you really know jerk.

    I can't believe for one moment that you ever were in the field
    professionally.

    You're really showing your true colors..
