    Dear everyone,

    I am a beginner in turbulence research using DANTEC/DISA Hot wire anemometer.

    I am right now working on CTA 56C17 Bridge adjustment, which is mandatory before calibration and measurement. I am facing difficulties in CTA 56C17 manual bridge adjustment. I have the following questions in my mind, will anybody be kind enough to clear my following doubts:

    1)Before CTA 56C17 bridge adjustment, what should be the settings in APU 56N23 unit:
    Differentiator (mSec) knob position
    DIR/SUB/ADD knob position
    DC/0.1Hz/2Hz knob position
    Gain knob position

    2)Before CTA 56C17 bridge adjustment, what should be the settings in 56N26 Signal Conditioner unit:
    HP Filter setting
    LP Filter setting
    Gain setting

    3)Before CTA 56C17 bridge adjustment, what should be the settings in 56N25 RMS unit:
    Integration Time
    Input ch.no selector

    4)Before CTA 56C17 bridge adjustment, what should be the settings in 56N22 Mean value unit:
    Integration Time (FILTER/1/10/100/1000) Sec.
    Input selector light position

    5)Before CTA 56C17 bridge adjustment, where should D.C. Voltmeter be connected in the rear panel, out of 16 BNC Output sockets?
    (I generally connect the probe cable to the BNC socket designated PROBE in the left most CTA 56C17 Bridge.)

    Kindly help.
