For Your Safety:
PLEASE
•
READ THIS MANUAL IN ITS ENTIRETY BEFORE ATTEMPTING INSTALLATION OR
OPERATION!
Attempting to operate the Model 7100P Portable analyzer without fully understanding its features
and functions may result in unsafe conditions.
•
Always use protective eye wear and observe proper safety procedures when working with
pressurized gases.
•
Always assure the pressure of gas entering the Model 7100P Portable analyzer is 1-3 psig.
•
Always calibrate the Model 7100P Portable analyzer at an equivalent pressure and flow rate to the
measured gas.
•
Always allow the Model 7100P Portable analyzer sensor to cool down before attempting to access
the sensor.
•
Properly dispose of the oxygen sensor when it has expired.
•
Ensure the MODEL 7100P Portable analyzer has been properly calibrated before use.
•
Never expose the analyzer chassis or sensor to water, high humidity or moisture. The analyzer
chassis is not watertight.
•
Never expose the MODEL 7100P Portable analyzer to flame or high temperatures.
•
Never expose the MODEL 7100P Portable analyzer directly to unregulated gas lines, cylinder gas,
… High gas pressures may cause the oxygen sensor to rupture.
•
Ensure the analyzer unit is mounted in an area of free air flow to prevent the chassis from
exceeding the operating temperature specifications. Do not mount the analyzer or sensor against
hot surfaces. Do not block the ventilation louver on the analyzer chassis.
•
The standard Model 7100P Portable analyzer is not explosion proof or Intrinsically Safe. Do not
expose to
flammable substances.
•
Before powering up the model 7100P, it is important to purge the sensor of ambient air.
This will facilitate a quick initial response to ppm levels of oxygen .
The sensor used in the
model 7100P Portable analyzer is designed for use in PPM concentrations of oxygen. If the
analyzer is powered up while the sensor is exposed to ambient air, then the sensor will saturate with
oxygen and may require up to 5 minutes recovery time once exposed to trace oxygen gases. To
prevent this delay due to saturation
, you should flow ppm level oxygen (or zero gas) to the
sensor before power up
. It takes approximately 5 seconds to sweep the sensor out when zero gas
is swept through the analyzer. Then you can apply power to the analyzer. Exposure to air does not
affect the life of the sensor. Likewise, also flow ppm level oxygen to sensor for 5 seconds after
power off.
