30 Agilent ADM Flow Meter Operating Instructions
Upgrading the Firmware/Retrieving Certificate of Calibration
When a newer version of the flow meter firmware is available, you can upgrade to
the latest version using your PC via the USB connection of the ADM Flow Meter.
Please visit http://www.agilent.com/chem/ADMflowmeter for instructions.
It is also possible to retrieve a digital copy of your cartridge's Certificate of Calibra-
tion in PDF form though the Flow Meter's website. Please visit http://www.agi-

A Note About Back Pressure
The ADM cartridge is calibrated with the standard flexible tubing supplied with the
meter at the time of purchase. Replacement tubes should be of equal ID and
length. Be aware that using tubing that increases or decreases the total volume of
gas in the tubing will affect accuracy. Tubing of greater volume will result in slightly
lower flow readings. This is because the transducer creates an ever-so-small back
pressure that compresses the gas slightly.
