  • Page 29: Section 5 Options Setup

    Section 5 Options Setup The WIN3654 program is an integral part of the analyzer. Running under Microsoft Windows®, it permits you to list and analyze up to 500 stored measurement values. The program also includes a special monitoring feature, which lets your computer act as a chart recorder, and enables a hardware test to ensure that the system is in good working order.
  • Page 30 Options Setup The Monitoring menu creates a running chart of real-time measurements (see Monitoring measurements in real-time on page 24). These values can also be saved to the Windows Clipboard. The Configuration menu lets you see how your system has been configured for your application.

  • Page 31: Analyzer - Pc Connection

    Lange representative. 5.4 Configuring the instrument The ORBISPHERE 3654 analyzer can be readily configured for your application using the following commands in the Configuration menu. The instrument must be connected to your PC and powered on, in order to change any configuration parameters.

  • Page 32: Measurement Units

    Options Setup The gas measurement phase can also be selected from the instrument keyboard as follows: 1. Switch the instrument power 2. Switch the instrument on by holding down the button and then pressing the button while still pressing POWER button 3.

  • Page 33: Membrane Selection

    Note: You can create a solution having a known H or N concentration by dissolving H or N in water at a measured temperature and pressure. Hach Lange can provide equipment for generating such a solution. Alternatively, you can analyze a carbonated beverage independently by other acceptable means.

  • Page 35: Section 6 Calibrations

    Section 6 Calibrations 6.1 Barometric pressure sensor calibration You must have access to an accurate barometer to calibrate the instrument's internal barometric pressure sensor. This is done using the PC WIN3654 program. Choose Troubleshooting, Pressure Calibration and a message will warn that the current calibration will be lost.

  • Page 36: Calibration Setup

    Calibrations Ensure that normal measurement mode is selected in the Measurement Mode menu of the WIN3654 program (see Measurement mode on page 32). Calibration must only be carried out once the TC sensor is giving a stable measurement. Expose the membrane to the calibration sample until this stable reading is obtained. This usually takes about 5 minutes.

  • Page 37: Calibration In H Or N At Atmospheric Pressure

    Calibrations 6.2.2 Calibration in H or N at atmospheric pressure The sensor can be calibrated in pure H or N gas at atmospheric pressure. WARNING Handle H gas with great care. It is extremely flammable and explosive. To ensure that the flow chamber and sensor components are dry, remove and blow dry the flow chamber.

  • Page 38: Calibration In H Or N At Elevated Pressure

    Calibrations 6.2.3 Calibration in H or N at elevated pressure The sensor can be calibrated in pure H or N gas at an elevated pressure. This method requires an accurate pressure gauge connected to the exit of the flow chamber. WARNING Handle H gas with great care.

  • Page 39: Calibrating In A Liquid H Or N Solution

    Calibrations 6.2.4 Calibrating in a liquid H or N solution The sensor can be calibrated in a standard liquid solution that has a known concentration of H or N You can create a solution with a known concentration by dissolving H or N in water at a measured temperature and pressure.

    The membrane needs to be replaced once or twice a year depending on application conditions. This can be tailored accordingly. Note: If you are not familiar with ORBISPHERE sensor servicing, your Hach Lange representative will be glad to assist you.

  • Page 44: Testing The Sensor Condition

    Maintenance and Troubleshooting 8.2.3 Testing the sensor condition Periodically, visually inspect the sensor head for any deposits. Rinse it under clean tap water, and dry with a clean tissue. To verify the sensor, check measurements vs. a known standard sample value: If reading deviation is ±1% of the expected value, no action needs to be taken.

  • Page 45: Installing The Membrane

    Maintenance and Troubleshooting 8.3.2 Installing the membrane To install the new membrane, follow the steps below: Note: The membrane mounting surface must be clean and even (on top of the sensor, where the membrane and sensor have contact). Replace the membrane O-ring on the sensor head with a new one.
  • Page 46 Maintenance and Troubleshooting Note: Distinguish the membrane from the protection paper: - Membrane is transparent (translucent). - Protection paper is opaque. The membrane diameter is larger than the sensor head diameter. This is normal, as the membrane will fold over the sensor tip.

  • Page 47: Purge Gas Cylinder Refill

    Maintenance and Troubleshooting Finally replace the flow chamber. Gently lower the flow chamber onto the sensor, guiding the thermistor on the sensor into the hole in the flow chamber base. Turn the flow chamber locking pin (see Figure 1 on page clockwise to secure it in place.

  • Page 48: N 2 Purge Gas

    Maintenance and Troubleshooting 8.4.1 N Purge gas Fill the N purge gas cylinder to a maximum of 200 bar from a master N storage cylinder, using fittings supplied with the analyzer. CAUTION Although N is not toxic, it is asphyxiating. Therefore, filling should be carried out in a ventilated place and leaks should be avoided.
