DANGER
This instrument is designed to monitor the helium concentrations in a gas mixing
process. When processing gas mixtures intended for breathing, the instrument must
be calibrated and functioning properly. Suffocation or other fatal respiratory
complications can result from improperly calibrated or malfunctioning equipment.
Oxygen accelerates combustion. Do not use this instrument around open flames and
combustible gases, liquids or solids.
Only authorized personnel should conduct maintenance and/or servicing. Before
conducting any maintenance or servicing, consult with authorized
supervisor/manager.

Calibration
Note: The sample gas must be flowing to accurately
calibrate the instrument
Helium sensor
The Helium sensor is supplied fully calibrated and should not
require adjustment for approximately 30 days. For calibration
information please refer to the instruction manual.
Operation
To operate the PRO HE
1. Turn the power on.
2. Attach the sample line using the supplied adapters
and allow the gas to flow into the instrument at 1-2
LPM. If the readings on the LCD display appear
wrong shut the gas off and observe readings. If they
drop within a few seconds the gas flow is too high.
Reduce flow or use the cylinder valve to turn the gas
on and off until a stable reading is achieved.
