Zero Adjustment Function (*2):
By using the parameter setting, zero adjustment is
carried out to ensure that the output for zero flow is
0%. Zero adjustment should be carried out only when
the flowtube is filled with measurement fluid and the
flow is completely stopped by closing the valves.
During zero adjustment (450 seconds), the current
output is 10.4 mA.

Wetted Part Material:
Lining;
Fluorocarbon PFA *1 lining
*1: PFA is FDA (U.S. Food and Drug Administration) ap-
proval material.
The inner surface of the PFA lining is mirror-finished to
Ra of 0.05 to 0.15 μm. The value of Ra is the average
of measurements at several points. Mirror finished
PFA lining is standard for size 25 to 100 mm (1 to 4 in.)
and optional for size 150 to 200 mm (6 to 8 in.) speci-
fied by optional code PM.
Electrode;
