    No time for temperature measurement instrumentation theory 101
    today so I'll just give you the typical values for the coolant
    (and oil) temperature channels.  Just plug these values in and see
    what happens.
         Scale factor -  2.151
    Low end offset  - 100
    Sensor offset -  390
    Low alarm limit  - 0  (or whatever you want)
    High alarm limit -   210 for 2 & 3 gen, 225 for Renesis
         If still no joy, disconnect the temp sensor and check reading for
    change.
    If no change,  disconnect wire for coolant temp at EM2 connector
    and check for change
         If still no change, EM2 is bad (not likely since similar channels
    on unit are working)          Most likely problem is a short to ground on the sensor line.
         Hope this helps.

        Shocking....Chris is asking another question about the
        EM2.  Hey, me asking
        questions means I am out there trying to make
        progress......not that I am
        defensive or anything <g>

        Anyway, since my "buttons" issue the Coolant Temperature on
        the main screen
        has been showing "0".    The oil temp is working ok.  I
        figured that I must
        have inadvertently set it to 0 when I was having my button
        problem.  I
        figured now that the buttons are working properly I could just
        go and
        calibrate it.  Figured a good starting point would be to use
        the cold oil
        temp as a guide.  However, when I try to calibrate it, it will
        not change
        from zero.  I thought that maybe there was not % change from
        zero and I
        tried changing other calibration modes but nothing I have
        currently tried
        has changed it from zero.  I admit to very little current
        understanding of
        the calibration feature at this time (even though  I really
        like that it is
        included in the EM2....I like options even though they can be
        a pain
        sometimes).

        Any direction on how to get this off of zero would be helpful
        as I am
        hesitant to start the dang thing 'till I can know how hot the
        coolant
        is....I know I can get some idea from the oil, but still.

        David Staten will probable be much better at figuring this
        out, but we have
        not been able to meet up for actual progress in the last few
        days.  TIA.

        All the best,

        Chris
