IDS-“Q” Pumphead
direction <right to left
Displacement is adjusted by
changing Angle of pumphead.
Loosen 11/32 hex nut and move
pumphead “left to increase” and
“right to decrease”.
Now recalibrate. Lock hex nut set
and lock Displacement adjust
stop screw.
CALIBRATION RING
FIXED CALIBRATION LINE
The Knurled ADJUSTMENT NUT on the
pumphead controls stroke to stroke
Piston displacement. Turning clockwise
to zero stops displacement. Turning the ADJUST-
MENT-NUT counterclockwise four and one half turns
from zero (450 on scale) (fig.5) causes maximum
pump reciprocation, e.g., 50 µl per stroke for the H-0
or 100 µ for H-1 unit.
Thus each 1-1/8 turn (112.5 on scale) of the AD-
JUSTMENT NUT Represents 25% of maximum
(12.5µl for H-0 and 25µl for H-1) and each graduation
on the ring represents an adjustment of 1/450th of
maximum (0.111 µl for H-0, 0.222 µl for H-1).

7.0 Calibration and Displacement
Your IDS comes factory calibrated to maximum displacement of the installed pumphead unless ordered
with specific displacement and calibration.
Recalibration and changes of displacement are relatively easy.
7.1 Calibration for Dispensing
FMI calibrates by weighing 3 or more dispenses on an analytical balance. It then finds the average. The
pumphead displacement is then adjusted as required up or down accordingly. See Fig
