    INTRODUCTION PortaSens II The PortaSens II is a rugged, hand-held device used to detect leaks of toxic gas, and also to detect oxygen displacement or deprivation. It adapts quickly to measure different gasses by inserting the appropriate gas sensor module. The modules retain all of the calibration and configuration settings for the target gas, such as the full scale range and alarm settings.

  • Page 12: Smart Sensor

    PortaSens II Portable Gas Leak Detector, Model C16 SMART SENSOR The PortaSens II measures gas concentration levels using “Smart Sensor” modules, which store their calibration and configuration settings, such as, zero, span, range, and alarm levels. This allows them to be quickly changed to detect leaks of different toxic gasses, or to detect oxygen displacement or deprivation.

  • Page 13: Sensor Response Times

    PortaSens II Portable Gas Leak Detector, Model C16 Sensor Response Times The table below lists the time required to obtain readings of 66%, and 90%, of an instantaneous exposure to various gasses. The times listed are for the sensor only, and do not include travel time through the wand or tubing, or digital damping by the device.

  • Page 14: Gas Interferences

    PortaSens II Portable Gas Leak Detector, Model C16 Gas Interferences Some sensors exhibit a minor sensitivity to non-target gases and vapors. Table 3 lists the cross- sensitivity factors of sensors to various, “interference” gases. To use the table, find the sensor type along the top, and then scan down the column for the factor corresponding to one of the interference gases listed on the left.
  • Page 15 PortaSens II Portable Gas Leak Detector, Model C16 Notes on Interference Table: Sensors marked with an asterisk (*) in the oxygen column are 3 electrode sensors that require a minimum of 5% oxygen to operate properly. Hydrogen sensors require oxygen levels at least two times the maximum percent hydrogen value to be measured.

  • Page 16: Operation

    OPERATION Quick Start The PortaSens II is simple to operate. After removing the device from the storage case, install a gas sensor module (see Changing the Sensor on page 12) and plug the sampling wand into the inlet port of the manifold (Figure 2 on page 7).

  • Page 19: Batteries

    PortaSens II Portable Gas Leak Detector, Model C16 Batteries The primary battery is a standard, alkaline D-cell. It is housed in the handle of the device and will operate the device continuously for approximately 75 hours. If the primary battery becomes discharged, or disconnected, a secondary (rechargeable) battery will supply power for up to 6 hours.

  • Page 20: Led Indicator

    PortaSens II Portable Gas Leak Detector, Model C16 LED Indicator The LED on the panel indicates battery status. It lights steady when the charge cable is connected. When the cable is disconnected, the LED flashes once every six seconds to indicate the device is capable of starting (one, or both, batteries are ready).

  • Page 21: Response Test

    PortaSens II Portable Gas Leak Detector, Model C16 Response Test A response test is recommended before each use. Table 5 lists methods for generating gas that are appropriate for a target gas. Contact ATI for details on other methods. Table 5. Gas Generation Methods.

  • Page 22: Inlet And Outlet Extensions

    PortaSens II Portable Gas Leak Detector, Model C16 Inlet and Outlet Extensions The inlet port is located on the manifold lid and features a quick-disconnect fitting (see Figure 2 on page 7). The fitting permits connection of the flexible wand, for probing around mechanical equipment, and sampling confined spaces without entering.

  • Page 23: Operating Modes

    PortaSens II Portable Gas Leak Detector, Model C16 Operating Modes The four operating modes of the device are Normal, Sample, Configuration, and Calibration mode. The mode affects how, and when, the gas concentration reading is updated on the display. The operating mode also determines if alarms are enabled or disabled (inhibited).
  • Page 24 PortaSens II Portable Gas Leak Detector, Model C16 The device displays the time remaining in the second interval while it collects readings and averages them. On MEASURING 00:30 expiration, the device beeps and continues with display ABORT SM3. ABORT – ends Sampling mode and returns to the Main Display, D10, and resumes Normal mode.

  • Page 25: Alarms

    PortaSens II Portable Gas Leak Detector, Model C16 Alarms The device features three level alarms designated as Caution, Warning, and Alarm, in order of increasing severity. The levels are stored in the H10 sensor memory, and are read at startup, and when a sensor is installed.

  • Page 26: Low Flow Alarm ("Pump Trouble")

    PortaSens II Portable Gas Leak Detector, Model C16 Low Flow Alarm (“Pump Trouble”) The device contains an internal diaphragm pump, which forces a continuous sample stream of gas to the sensor at a rate of approximately 400 cc/min. A blockage in the inlet or outlet port causes the pump motor to stall, and the device compensates by increasing the pump motor speed.

  • Page 27: Device Configuration

    Portable Gas Leak Detector, Model C16 DEVICE CONFIGURATION The PortaSens II configuration is the combined user and calibration settings stored in the device and H10 sensor memories. Some settings are considered critical to the safe operation of the device, and require a special key press sequence to change them.

  • Page 35: Sensor Calibration

    Portable Gas Leak Detector, Model C16 SENSOR CALIBRATION The PortaSens II sensor calibration is a two-step process referred to as Zero and Span. Each calibration adjusts settings that are used to compute the gas concentration reading. Since the settings reside in the sensor module, modules may be calibrated separately, and used in any device.

  • Page 36: Span Calibration Steps

    PortaSens II Portable Gas Leak Detector, Model C16 Pressurized Gas Sources Supplying gas to the device from a pressurized source requires a bypass-T to be inserted between the source and the manifold (Figure 11 below). This is required to limit gas pressure on the intake side of the sample pump when the source is open, and prevent the inlet from being blocked when the source is closed.
