If a cuvette is not inserted in the instrument, see 2 below: 2. Intensities are out of range. The cable from the detector to the circuit board is disconnected.

There is no power to the LEDs. The LED cable may be loose, disconnected or improperly placed on the connector at one or both ends. One or more LEDs is defective. There is no power to the printer.

The printer is not connected to the instrument. The wrong print mode, baud rate, or parity is selected. Press the and keys simultaneously to turn the instrument off, then turn the instrument back on. Remove cuvette, turn unit off and restart. At "Cuvette Inserted??? Press any key and then press to readjust light sources. When program finishes, turn the instrument off and then on. Open the case and check that the cables are properly connected. Connect the printer to an AC outlet and turn on the printer.

Specify the proper values for the printer see page See above. The optical detector may be contaminated by blood or foreign material. The instrument may require calibration.

The wrong cuvette pathlength is entered into the instrument. Equal values were entered for Pulm. Venous and Pulm. An incorrect entry was made for one of the entered quantities.

A cuvette without a sample was inserted. The cuvette was not properly filled. Run optical quality control. If needed, clean the optical detector see page Re-calibrate the instrument see page Obtain the correct cuvette pathlength value from the cuvette carton and enter the value see page Clean the optical detector see page Obtain correct values for Pulm. Review and, if necessary, re-enter correct values. Test a new cuvette that contains the sample.

Remove residual dried blood or other foreign matter using a water-dampened cloth. Only qualified personnel should perform maintenance as described in this manual.

Cleaning the Optical Detector Materials Needed: 1. Remove the four screws from the bottom of the instrument, using the 0 Phillips screwdriver. Holding the upper and lower covers together, place the instrument in the upright position, with the keypad to your right.

Slowly and carefully lift the upper cover, keeping it parallel with the lower part of the instrument, until the upper cover is free of the rear panel.

Locate the cable that runs from the battery pack to the main circuit board see below. Disconnect the cable from the J connector on the main circuit board. Tilt the upper cover backward to fully expose the main circuit board and small circuit board on the lower part of the instrument.

Locate the flat keypad cable that runs from the keypad to the main circuit board. Disconnect the cable from the Keyboard J connector on the main circuit board.

Keypad Cable 8. Disconnect the cable from the Display J connector on the main circuit board. Note: Grasp only the connector at the end of the cable. Gently rock the connector in an upward direction to remove it. Locate the flat cable that runs from the black optical unit to the main circuit board. Locate the coaxial cable that runs from the black optical unit to the small circuit board. Disconnect the cable from the J1XX connector on the small circuit board.

The upper cover containing the black optical unit can now be rested on a table with the front panel facing down. Using the 5mm nutdriver, remove the four nuts and washers, if applicable that secure the black optical unit to the front panel. Then remove the black optical unit from the instrument. Take care when separating the two halves of the optical unit.

Do not lose the small torsion spring or the shutter door. Set them aside in a safe place for reassembly. Clean the exposed detector with gauze pads dampened with detergent. Do not use abrasives. Then dry off the detector surface, making sure that it is clean. Remove any other debris inside the optical unit. Reassemble the two halves of the optical unit, making sure that the shutter door and torsion spring are installed correctly the two door ribs will face outward.

One leg of the spring fits into a hole in the door slot, the other leg rests behind the shutter door. Bolt the optical unit back together. Place the optical unit back on the front panel. Using the 5mm nutdriver, secure the black optical unit to the front panel with the four nuts and washers, if applicable.

Position the upper cover containing the black optical unit in an upright position over the lower part of the instrument, with the keypad to the right. Connect the coaxial cable from the optical unit to the J1XX connector on the small circuit board. Connect the flat cable from the optical unit to the J connector on the main circuit board. Connect the flat cable from the keypad to the Keyboard J connector on the main circuit board.

Connect the cable from the battery pack to the J connector on the main circuit board. Slowly and carefully lower the upper cover onto the lower part of the instrument, ensuring that the metal rear panel slides into the center slot at the rear of the upper cover. Note: Ensure that the cables are not snagged or crimped between components when lowering the upper cover onto the lower part of the instrument. Using the 0 Phillips screwdriver, secure the bottom of the instrument to the upper cover with the four screws.

Menu Commands Access Main Menu Press the key when a test is not running or another menu is not active. Page Test Cuvettes Federal, state and local laws and regulations require that hazardous waste be disposed of in a specific manner. Waste material from the AVOXimeter E which may be classified as biohazardous include used cuvettes. It is important that steps be taken to dispose of these materials in accordance with the prevailing regulations in your location.

Page Connections Figure 4. The instrument is factory preset for a standby delay time of 60 minutes, but a time of 10 to minutes can be specified see page Page Optional Materials This eliminates the risk of the instrument powering down during a test.
