    Part 5 – Configuration General To turn the system ON, simply press and hold the MENU key for approximately 5 seconds and the display will come on. To turn the unit off, press and hold the ENTER key until the display shuts off (about 3 seconds). Note that the unit must be in the MEASURE menu in order for the 3-second key press to operate.

    Part 5 – Configuration Q45D-ODO Optical D.O. System MODE This switch is used to set the voltage at which monitor will shut off when powered by internal batteries. Alkaline batteries can normally be run down to about 0.8 volts. When using alkaline batteries, the mode switch is in the OFF position (factory default).

  • Page 18: Software Interface

    Part 5 – Configuration Q45D-ODO Optical D.O. System Software Interface The user interface for the Q45 Series instrument consists of a custom display and a membrane keypad. All functions are accessed from this user interface (no internal jumpers, pots, etc.).

  • Page 19: 5.51 Keys

    Part 5 – Configuration Q45D-ODO Optical D.O. System 5.51 Keys All user configurations occur through the use of four membrane keys. These keys are used as follows: MENU/ESC To scroll through the menu section headers or to escape from anywhere in software. The escape sequence allows the user to back out of any changes in a logical manner.
  • Page 20 Part 5 – Configuration Q45D-ODO Optical D.O. System Lower Line During normal operation, the lower line of the display indicates user-selected secondary measurements that the system is making. This also includes calibration data from the last calibration sequence and the transmitter model number and software version.

This menu is a display-only measurement menu, and has no changeable list items. When left alone, the instrument will automatically return to this menu after approximately 30 minutes.

  • Page 26: Calibration Menu [Cal]

    Part 5 – Configuration Q45D-ODO Optical D.O. System % Saturation The most common display of D.O. in water is either PPM or mg/L units. However, the same PPM value at different water temperatures can represent quite different concentrations of oxygen in terms of the percent of saturation. This display simply indicates the % of oxygen saturation represented by the current PPM or mg/L display.

    Press ENTER to initiate user entry mode and the first digit will flash. Use arrow keys to modify value. See 49 for the Q45D lock/unlock code. Press ENTER to toggle lock setting once code is correct. Incorrect codes do not change state of lock condition.
  • Page 28 Press ENTER to store the new value. Zero Filter The Q45D allows the user to program a value near zero below which the monitor will read zero. Because sensors rarely have a perfect zero stability, this zero filter eliminates occasional displays of numbers that are not meaningful.
  • Page 29 Part 5 – Configuration Q45D-ODO Optical D.O. System Proc Cond The Q45D instrument also utilizes the process conductivity value as an input for the calculation of a theoretical ppm value during a saturation calibration. This value is only required to be entered during initial installation - it does not need to be modified at every calibration.

    During calibration, the system will display the current ppm reading and the user can manually enter a reference value from a lab sample or comparative reference instrument. In the Q45D system, the 1-Point calibration adjusts the slope of the sensor output response.
  • Page 35 Part 6 – Calibration Q45D-ODO Optical D.O. System If the sensor has been removed and placed into a bucket of water, allow sensor to temperature equilibrate with the solution as much as possible. With the sensor coming from an application which differs greatly in temperature, the user may have to wait as much as 20 minutes.

    Part 6 – Calibration Q45D-ODO Optical D.O. System 6.12 Dissolved Oxygen Air Span Cal (% sat) This is the recommended method for air temperatures greater than about 10C; however, it requires that the sensor be removed from the process and cleaned.

  • Page 37: 6.13 Dissolved Oxygen Zero Cal

    Part 6 – Calibration Q45D-ODO Optical D.O. System The system now begins acquiring data for the calibration value. As data is gathered, the units for ppm and temperature may flash. Flashing units indicate that this parameter is unstable. 8. The calibration data point acquisition will stop only when the data remains stable for a pre-determined amount of time (approximately 15- 20 seconds.) This can be overridden by pressing ENTER.
  • Page 38 Part 6 – Calibration Q45D-ODO Optical D.O. System 2. Place about an inch of zero solution in a small beaker or other convenient container and immerse the tip of the sensor. Allow the sensor to sit undisturbed for at least 15 minutes. Suspend sensor, DO NOT LET SENSOR SIT ON TIP.

  • Page 39: Temperature Calibration

    Part 6 – Calibration Q45D-ODO Optical D.O. System Temperature Calibration The temperature calibration sequence is essentially a 1-point offset calibration that allows adjustments of approximately ±5 °C. If sensor cable lengths beyond the standard cable length are being used the resistance of this added cable will affect the temperature accuracy and will have to be off-set to compensate for this added resistance.

The message Adjust value - press ENTER will be displayed, and the right-most digit will begin to flash, indicating that the value can be modified. Using the UP and LEFT arrow keys, modify the value to the known ref solution temperature.

  • Page 41: Part 7 - System Maintenance

    Part 7 – System Maintenance General The Q45D/60 Dissolved Oxygen System will generally provide unattended operation over long periods of time. With proper care, the system should continue to provide measurements indefinitely. For reliable operation, maintenance on the system must be done on a regular schedule. Keep in mind that preventive maintenance on a regular schedule is much less troublesome than emergency maintenance that always seems to come at the wrong time.
