  • Page 5: Introduction

    C16 Leak Detector INTRODUCTION The Series C16 PortaSens II is a portable, battery operated instrument designed to measure a variety of gases in ambient air. While C16 detectors can only measure one gas at a time, the unit uses interchangeable smart sensors so that it can be quickly converted to measure another gas.

  • Page 8: Operation

    PortaSens II Gas Detector C16 Leak Detector OPERATION Sensor / Charge LED The C16 is equipped with a sensor / charge LED to give the user a visual indication that the sensor is ready for immediate use. This LED will flash about every 3 seconds. The sensor LED will flash even when the batteries in the C16 are too low to run the instrument.

  • Page 9: Response Test

    PortaSens II Gas Detector C16 Leak Detector RESPONSE TEST Prior to using the detector for field measurements, it is recommended that the unit first be tested for gas response. A response test simply means drawing a sample from some type of container that will give off the type of gas you are looking to measure.

  • Page 10: Sample Inlet Options

    C16 Leak Detector SAMPLE INLET OPTIONS The PortaSens II is shipped with a quick disconnect inlet fitting connected to the sample inlet port. A flexible extension wand is supplied in the kit for use in probing around mechanical equipment to determine the source of a gas leak or for pulling sample from a confined area without entering the area.

  • Page 11: Response Time

    PortaSens II Gas Detector C16 Leak Detector RESPONSE TIME The response time for the gas sensors varies depending on the particular type of sensor. The following table shows the typical response times for sensor modules available for the C16 detector. The table provides typical time constants to 66% and 90% of exposure. This data should be used to determine how long you need to measure in a particular location to be sure you have a representative reading.

  • Page 12: Interferences

    PortaSens II Gas Detector C16 Leak Detector INTERFERENCES Individual gas sensors respond to other gases or vapors in various ways. Some sensors are very specific, exhibiting very little cross-sensitivity with other gases. Other sensors are not as selective, and will respond to a variety of gases if present. Refer to the tables on the following pages for data on the response of ATI gas sensors to other gases that might be present.

    This condition can occur if the pump is filled with water or if the filter becomes completely blocked. A flowmeter is included in the PortaSens II kit to allow quick verification of proper flow. Turn the instrument on and connect the sampling wand. Place the tip of the sampling wand into the tubing adapter attached to the flowmeter.

  • Page 17: Start-Up Sequence

    PortaSens II Gas Detector C16 Leak Detector START-UP SEQUENCE When the C16 power switch is activated, a number of messages are sequentially displayed. Note that the display always has a row of text across the bottom. The four switches on the front panel are called “soft switches” because they have different functions depending on what mode of operation the unit is in.

  • Page 18: Operating Modes

    PortaSens II Gas Detector C16 Leak Detector OPERATING MODES Look at the display D10 on the previous page. Along the bottom line you will see the key functions OFF, MENU, and SMPL. To turn the unit off, press and hold the OFF key as previously described.

  • Page 19: Sensor Module Exchange

    C16 Leak Detector SENSOR MODULE EXCHANGE The versatility of the PortaSens II leak detector stems from its ability to use a variety of sensor modules. These interchangeable modules allow one instrument to measure a wide variety of gases with extended range capabilities as described in the Introduction section.

  • Page 21: Programming

    PortaSens II Gas Detector C16 Leak Detector PROGRAMMING As previously mentioned, the C16 is ready to operate when received. However, there are a number of operating variable such as range, alarm setpoints, display damping, and sample mode timing that can be programmed. In addition, sensor module zero adjustment and calibration can be done from the programming menu.

  • Page 22: Adjusting Alarm Setpoints

    PortaSens II Gas Detector C16 Leak Detector ADJUSTING ALARM SETPOINTS The C16 contains three alarms, one for Caution, one for Warning, and one for Alarm. In the C16 as shipped from the factory, the Caution setpoint is programmed to detect negative drift of the sensor zero.

  • Page 23: Setting Display Variables

    C16 Leak Detector SETTING DISPLAY VARIABLES Three display variables may be adjusted on the PortaSens II. The adjustments include display averaging, display blanking, and display range. To adjust display variables, start from display PD2 (see page 20). Press the key marked DISP. The display will change to VD1 below.
  • Page 24 PortaSens II Gas Detector C16 Leak Detector The measuring range of the C16 detector depends on the sensor module installed. Display D8 (page 16) in the information displays shows the minimum and maximum full scale range for the sensor currently installed. Keep in mind the fact that the full scale range you set in this routine will only affect the voltage output, data logging functions, and sampling mode recovery setpoint.

  • Page 25: Setting Sample Mode Variables

    PortaSens II Gas Detector C16 Leak Detector SETTING SAMPLE MODE VARIABLES As previously explained, the C16 detector provides the capability of measuring gas concentrations using a predefined measuring cycle. The measuring sequence used in “Sample Mode” measurements include the following sequence.

  • Page 26: Calibration

    Calibration of the PortaSens II is recommended approx. every 6 months in normal use. If the unit is used very infrequently, yearly calibration should be sufficient. This can be done easily provided that the user has a reliable gas standard to use for the calibration procedure.

  • Page 33: Maintenance

    PortaSens II Gas Detector C16 Leak Detector MAINTENANCE Series C16 gas detectors require little maintenance. Sensors do not have a regular service requirement other than calibration, and pumps are sealed and permanently lubricated. The only item in the instrument that requires periodic maintenance is a filter that protects the pump against particulate that might cause it to stall.

  • Page 34: Troubleshooting

    C16 Leak Detector TROUBLESHOOTING The PortaSens II is a self contained instrument that does not require regular service. Only periodic calibration should be necessary to maintain proper operation. Should a problem arise with the unit, there are a few tests that can be done to determine the source of the problem.
