stroke sequence:
Display
1.
Apply a known, accurate pressure
source. This may be
true atmospheric
pressure, with known
reference defined by
a local barometer.
2.
Press MIN/MAX and
TARE keys at the
same time. (See
figure 1.)
Top line of display reads
“ZEROING SOURCE:”
3.
Press up ↑ or down ↓
arrow key until desired zero function is
shown on the bottom
line.
Bottom line of display
reads “USER ADJ.
ZERO”
4.
Press the PRGM key.
