Taking gas flow readings
To maintain the best possible accuracy and minimize thermal effects, Mesa recommends
fully charging your battery before taking measurements. If this is not possible, we recom-
mend disconnecting your Defender from its AC power adapter/charger while taking flow
measurements — or to run gas through your Defender for 10 minutes before starting the
flow measurement.
First steps

• Press the
On/Off
button for 1 second to turn on your Defender.
• When first turned on, your Defender displays an opening screen showing the product
name, model number and flow range.
• Press the
On/Off
button for 3 seconds to turn your Defender off.
Connect device to be calibrated to the appropriate Defender port. Use ¼ inch diameter
