Troubleshooting
Issue:
I dropped my meter. Is it OK? Do I need to recalibrate?
Action:
If it turns on and appears to respond normally, then it is prob-
ably OK. It may or may not need a recalibration. Compare
it against a known-good flow standard. If it checks out,
keep using it, but tell support about the drop at your next
annual recalibration so we can check it out for you.
Issue:
How can I see temperature, pressure or flow in different units?
Action:
From the main menu, select
BASIC CONFIG
→
DEVICE UNITS
.
From this menu, you can adjust temperature, pressure
or flow units. For more information, see
Flow Readings
Issue:
The live flow readings won’t settle down.
Action:
The flow meter is very fast, so it can detect subtle variations in flow
that may go unnoticed by your other flow devices. This sensitivity
can help detect problems with pumps or flow controllers. You
can lessen this sensitivity by increasing the flow averaging press

Issue:
My flow readings are negative.
Action:
If your flow meter is not connected to anything, it may be
reading a small flow that is entering its outlet. Plug one end
to see if the flow returns to 0. Under conditions of no flow, a
negative flow reading can indicate a poor tare. Ensure that
the flow meter has no flow passing through it, and select
TARE FLOW
from the Main Display to give it a fresh tare.
Issue:
My flow readings jump to 0 when flow rates are low.
Action:
Your flow instrument is equipped with a programmable zero band
that is preset at the factory. Reduce your deadband threshold by
selecting
MENU
→
ADV SETUP
→
SENSOR SETUP
→
ZERO BAND
. Note:
The zero band threshold has no effect upon the serial data.
Issue:
Does the meter work if it is laying down? Will it be accurate?
Action:
Yes to both! The flow meter is internally compensated for
any changes in orientation, so you can use it sideways,
on its back, or upside-down. S-series devices should
be tared again after changing their orientation.
Issue:
Can I put the meter on top of a vibrating
device? Will it be accurate?
Action:
Yes, and yes! The flow meter is internally compensated
for any changes in orientation, including rapid vibrations.
Sensor noise will increase if the flow meter is vibrating.
