•
Choose your engineering units. You
can choose the measurement units by
selecting MAIN MENU → SETUP → Sensor
→ Engineering Units, see page 15
for more details.
Operation: Flow Verification
•
Monitor live flow, temperature, and
pressure readings. Readings are
updated and displayed on your device
in real time. See page 6.
•
(Optional) Capture totalized readings.
The totalizer option displays the total
flow that has passed through the device
since the last time the totalizer was reset.
If your device has a totalizer, press NEXT
from the main live data display to access
the totalizer. See page 11.
