Warnings And Cautionary Statements - Industrial Scientific Ventis Pro Series Product Manual


CSA has assessed only the %LEL combustible gas detection portion of this instrument (the sensor part number 17155304-M only) for
performance according to CSA Standard C22.2 No. 152. Within an ambient temperature range of T
±3%. Within an ambient temperature range of T
been calibrated to 50% LEL CH
CAUTION: CSA C22.2 No. 152 requires before each day's usage, sensitivity must be tested on a known concentration of pentane or
methane equivalent to 25% or 50% of full scale concentration. Accuracy must be within -0% to +20% of actual concentration. Accuracy
may be corrected by referring to the zero and calibration section of the Product Manual.
ATTENTION : CSA C22.2 N°152 exige que la sensibilité de l'instrument soit testée avant l'utilisation quotidienne de l'instrument sur une
concentration connue de pentane ou de méthane équivalente à 25 % ou 50 % de la concentration totale. L'exactitude doit être entre -0 %
et +20 % de la concentration réelle. L'exactitude peut être corrigée en se référant à la partie concernant la mise à zéro et l'étalonnage
dans le Manuel du produit.

Warnings and Cautionary Statements

Read and understand this Product Manual before operating or servicing the instrument. Failure to perform
certain procedures or note certain conditions—provided below and throughout the manual—may impair the
performance of the product, cause unsafe conditions, or both.
Table 1.3 Warnings and cautionary statements
If it appears that the instrument is not working correctly, immediately contact Industrial Scientific.
Only qualified personnel should operate, maintain, and service the instrument.
Substitution of components may impair intrinsic safety, which may cause an unsafe condition.
Substituer des composants peut compromettre la sécurité intrinsèque, ce qui peut résulter en une situation
dangereuse.
Do not use in oxygen-enriched atmospheres. If the atmosphere becomes oxygen enriched, it may cause
inaccurate readings.
Oxygen-deficient atmospheres may cause inaccurate readings.
A rapid increase in a gas reading that is followed by a declining or erratic reading may indicate an over-range
condition, which may be hazardous.
Sudden changes in atmospheric pressure may cause temporary fluctuations in gas readings.
Temperatures below -20 °C (-4 °F) are likely to cause decreased functionality in the instrument's display screen
and man-down feature.
Sudden changes in ambient-air temperature will cause a form of sensor drift in the Carbon Monoxide/Hydrogen
Sulfide (CO/H S) sensor (part number 17155306-J) that will produce temporary variations in the sensor's

If the temperature suddenly increases, the CO reading will temporarily decrease and the H
temporarily increase.
