    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.
  • Page 9 Table 1.3 Warnings and cautionary statements  If the temperature suddenly decreases, the CO reading will temporarily increase and the H S reading may temporarily decrease. The readings will stabilize when the sensor has acclimated to the change in temperature. For example, if the ambient-air temperatures changes from a "room temperature"...

  • Page 10: Recommended Practices

    Table 1.4. These recommendations are provided to help support worker safety and are based on field data, safe work procedures, industry best practices, and regulatory standards. Industrial Scientific is not responsible for determining a company’s safety practices or establishing its safety policies, which may be affected by the directives and recommendations of regulatory groups, environmental conditions, operating conditions, instrument use patterns and exposure to gas, and other factors.

  • Page 11: First Use

    The instrument performs a self-test during power on. For an instrument that is set for always-on, the instrument will automatically perform a self-test every 24 hours. The self-test can also be completed on demand by the instrument user. Note: The use of calibration gases not provided by Industrial Scientific may void product warranties and limit potential liability claims. First Use...

  • Page 12: Remote Sampling

    When sampling with the aspirated instrument, allow time for the air sample to reach the sensors and for the sensors to respond to any gases that are present. Industrial Scientific recommends the allowance of two minutes plus two seconds for each foot of sample tubing.

  • Page 64: Warnings

    Warnings Warnings turn on and off repeatedly. The more urgent the warning, the shorter the time between on-off occurrences: a warning that repeats every two seconds is more urgent than a warning that repeats every thirty seconds. Warnings persist until the event is resolved. In some cases, an unresolved warning will cause an alarm. For example, if the man-down warning turns on and the instrument operator does not turn it off, the instrument and its signals will change from warning status to alarm status.

  • Page 85: Assignments

    Procedures Introduction When user and site names are assigned to Ventis Pro Series instruments, the information is saved in the instrument data log. Assignment data can provide valuable insight into exposure data and user behavior, while being useful when managing assets and investigating potential issues. Instrument assignments can be made using iNet or DSSAC, with Accessory Software, through instrument settings, and with iAssign.
  • Page 86 Sample scenario 2: The iAssign app can be used to assign the location “Tank 1” to an iAssign tag. The tag can then be installed at the entrance to Tank 1. When Ventis Pro Series instrument operators enter Tank 1, they can touch their instruments to the tag and the location assignment will be saved to the instrument.

  • Page 91: Appendix

    Appendix Supplemental Information about Gases and Sensors Toxic Gases A sensor is designed to detect for and measure the presence of a particular gas, the "target gas"; however, it may also respond to other gases. When this is the case, the sensor is said to have "cross-sensitivity" to another gas, which will interfere with the target-gas readings.

  • Page 92: Combustible Gases

    Combustible Gases Tables A.2 and A.3 provide the LEL for select combustible gases as they apply to specific sensors. These tables also provide correlation factors that can help determine the percentage LEL when the actual gas differs from the gas that was used to calibrate the instrument. For example, if the instrument reads 10% LEL in a pentane atmosphere, and was calibrated to methane, the actual percentage LEL is determined as follows: Locate the table cell where the sample gas (pentane) intersects with the calibration gas (methane).
