    Best point for temp measurement

    Hi All

    Just wondering what is the best place to measure engine temps with my Duratrax flashpoint. Should I point it down the opening or would pointing it at the base of the engine or a little higher on the side be more accurate?
    Been pointing down the hole up by the glow plug wire and temps seem to be low and fluctuate quite widely.

    Thanks

    From the manual:
    a. Make sure the gaugeís sensor is as close to the
    object as possible, preferably within 1 inch, so
    that the infrared sensorís field of view is fully
    focused on the object. Attempting to read
    temperatures with the gauge further away from
    the object will result in less accurate readings.
    b. Always point the sensor directly at the object
    being measured. Try not to have the gauge
    tilted at a different angle in relation to the
    object being measured.
    c. It may be a good idea to re-measure the
    temperature of an object at a slightly different
    location on the object, to reconfirm the
    accuracy of the reading.
    d. Try to avoid allowing sunlight or other artificial
    light from beaming in-between the gauge and
    object being measured, as heat from such light
    could skew actual readings. For the same reason,
    also try to prevent wind from blowing in-between
    the gauge and object being measured.
    e. Generally, higher air or ambient temperatures
    lend to more accurate readings. Cold ambient
    temperatures can result in inaccurate
    readings. Ambient or air temperature refers to
    the area around the infrared temperature
    gauge, the higher the temperature the more
    accurate the reading, the lower the
    temperature the less accurate the readings.

    I use at a 90 degree angle to the top of the cooling head and 1" away from the top of the head.
    One shot.....One kill, no exceptions

    Yeah, I got the manual in front of me here...I just heard some guys take measurements on the side of the engine down about half way....just wondering I guess if this is an accepted method or not.

    I take mine right at the glow plug.
    I wanted to put a really cool signature but I ran
