    Is that on its way to you or have you flogged it already?

    Unit hasn't been dived in ten years going off test stickers but is in good nick.

    I have changed o rings and regreased and installed new breathing hoses. Have fitted new orifice in gen 1 MAV, haven't been able to sort flow rate yet cos bought wrong spanners.

    Amazingly the ADV seems ok as do mushroom valves.

    Just taken out CL's to sterilise, is Milton ok for this?

    I have new DS4's on it and have had to remove the manifold because cylinders were handed to suit 02 on right, unit was set up for o2 on left.

    I have reworked hose routes to accommodate this which was planned anyway, but now dil first stage feeds hp gauge, wing, and ADV direct via a miflex hose and standard rubbers so think I will need an opv in first stage?

    BOV is plumbed into off board bailout with suit and a second stage.

    The handsets are original black triples but haven't come to life, I have used 1.5v N batteries but haven't opened or connected new cells yet and wasn't sure if they complete the circuit?

    If they are knackered i do have a pursuit and hud with kidney on way back from service but triples would have been good back up/spare.

    On The whole pleased with it and think I got a good deal.

    Dry suit
    Hollis reg with octopus and first stage
    Undersuit
    Heiser 3l dumpys and test
    2 Poseidon first stages which will do for suit inflation and second stage bottle eventually
    2 litre ally suit bottle and test
    The unit with some spares
    L.p. Hoses
    Pressure gauges

    All in 2.5k.

    I thought the batteries were about 12v.

    I know nothing of the KISS but if the cells are needed to complete the circuit, that would be a design fault IMHO unless someone can convince me otherwise

    The Kiss has 3 totally independent O2 analysers. As simple as the home made ones you can find plans for on the 'net, I.e. an LCD meter, power supply and a resistor bridge to do the sums. In it's simplest form, you could measure the output of the cell across a resistor (It's a current course,not a voltage source) and multiply the milivolts by a constant to give PO2, the resistor bridge just prevents you having to do sums underwater.

    One of the resistors is trimmable to allow for the output changing as the cell ages. This used to be a source of annoyance to the more ham-fisted owners as they used to strip the threads when they took the plug out to perform this adjustment.

    You can easily see lagging and aging cells as you're reading the meters in real time.
    However, to address your original point, the failure of any one meter will not affect the other two (unless the head is totally flooded), so there is a good argument to say that if the cell is not there, the meter could be blank.
    In fact it's not, it would read 00.0 in that event.
