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.
