Damping Adjustment
The 3150 Series amplifier boards for transmitter output code
options B (3152) and T (3153 and 3154) are designed to
permit damping of rapid pulsations in the pressure source
through adjustment of the single turn damping adjustment
potentiometer (see
). When adjusted to the
maximum position (clockwise stop), time-constant values of at
least 1.20 seconds are available for 3152, 3153, and 3154
transmitters. Transmitters with the electronics damping option
are calibrated and shipped with the adjustment set at the
counterclockwise stop, giving the minimum time constant.
Damping adjustment should be made with the transmitter
calibrated to the intended application calibration. To adjust
the damping, turn the damping adjustment potentiometer until
the desired time constant is obtained. It is best to set the
damping to the shortest possible time constant. Since
transmitter calibration is not affected by the damping setting,
damping may be adjusted with the transmitter installed on the
process.
CAUTION
The damping adjustment potentiometer has positive stops at
both ends. Forcing the potentiometer beyond the stops may
cause permanent damage and require electronics assembly
replacement.

If you remove either electronics housing cover during the
