    You can take it apart and clean the glass. Just as if you're changing the battery.

    Has anyone had issues with the low side consistently reading .5 inches off?

    Does anyone else have concerns about using low loss hoses on your guages because of zeroing issues?

    My ak900 reads .6 HG on the low side when not hooked up to anything...is this normal or should I get it calibrated?

    Press Zero.

    I use YJ ball valves on my hoses.
    The low loss should not be a problem as long as you remember to release any pressure in your hoses before zeroing the DRSA.
    We've been doing so much,for so long,with so little, that now we can do almost anything, with nothing at all.

    Don't want to violate EPA regualtion venting reffer into the atmosphere. Thats why i had those hoses, but according to the epa they are mandatory.

    A ball valve hose end qualifies as a low-loss fitting.

    The whole low-loss thing is a joke, anyway. You're going to have to vent that residual refrigerant sometime.

    The EPA recognizes that a certain amount of refrigerant is going to be lost during service procedures.

    Venting or purging hoses is part of that.

    Does anyone know how to calibrate the low side?
    Mine consistently reads 0.5 lower than high side even at standing pressure.
    Also my high side ball valve will leak by periodically (on manifold).
    Is there a rebuild kit that anyone is aware of?
    And while I'm at it....Is it normal for the low side to blink and quit reading at pressures above 130-150 psi? (even 410a)
    Thanks

    My ball valve leaked also. I was told to tighten the Allen screw on the side. I also noticed a machining issue on the interior under site glass .. Hope it doesn't break free into system although it appears ok but you never know

    I was aware that purging hoses was ok, bu thought that the point of low loss fitting was to not vent to the atmosphere why else would they require the use? I don't understand?

    So you don't blister your hands while working on a remote RT chiller condenser in 40 & under deg weather! Works for me!!
