Bluetooth Operation
The Bullseye Pirani comes equipped with a Bluetooth module, which interfaces with the Vacuum Gauge
Application for remote, real-time vacuum monitoring via Apple Store at

ranging up to
300 feet under ideal conditions.
To enable Bluetooth monitoring, scroll to the menu section marked Bluetooth, and enable or disable
the signal with the up or down arrow. See the included
Vacuum Gauge Application instructional
addendum
to enable app functioning.
Your vacuum instrument should give you many years of trouble-free service. There are no regularly
scheduled maintenance intervals. If consistent accuracy is required, it is recommended that the gauge,
tube, cable and power supply be returned for a yearly calibration check.
The instrument is calibrated in nitrogen, which has thermal properties virtually identical to air. Other
gasses will affect the readings by an amount proportional to the thermal conductivity of the gases. In
most cases, the gases present in a vacuum system will be air, nitrogen, or oxygen, and no appreciable
errors will occur.
Certain other gases, however, have thermal conductivity significantly greater than air and will cause the
instrument to read higher than the actual amount of pressure.
Examples of such gases are water vapor, fluorocarbon refrigerants, and acetone. Conversely, other
gasses have thermal conductivity significantly lower than air and will cause the instrument to read lower
