6.3 Calibration Procedure

1. Removeanysmudgesordirtfromthecalibrationcuvetteusinga soft material such as gauze. If necessary, clean the glass surface of the cuvette with a cotton swab dipped in methanol. Hold the cuvette by the narrow portion to prevent recontamination.

2. To begin the calibration cycle, depress and hold the START button until “ccc” appears on the LED display. Release the START button.

3. Thedisplaynowwillflashthevalueoftheexpectedcalibration cuvette (the instrument is set with the value of its calibration cuvette at the factory). The top of the calibration cuvette is labeled with its value, in mg/dL and μmol/L units.

CAUTION: IF THE VALUE ON THE CALIBRATION CUVETTE DIFFERS FROM THE VALUE BEING DISPLAYED BY THE REICHERT UNISTAT BILIRUBINOMETER, DISCONTINUE THE CALIBRATION PROCEDURE BY TURNING THE POWER OFF AND ON (TO CLEAR) AND REFER TO SECTION 11.2.

4. Open the black door and insert the specified calibration cuvette into the sample carrier until the widest portion of the cuvette is seated. Close the black door.

5. DepressandreleasetheSTARTbutton.Theinstrumentwillbegin its calibration cycle. When the calibration cuvette returns to its original position, the calibration procedure is complete.

E12 will appear if the calibration cuvette measurement is more

 than 1 mg/dL (17.1 μmol/L) different than the expected value. To correct:

• Be sure the correct cuvette (13103410) was used.

• Be sure the calibration value programmed matches the 13103410 calibration cuvette used (see Section 6.3).

• If the correct cuvette and value were used, the error may be the result of an optical problem. Contact your Reichert service representative.

E13 will appear if there is an electronic failure.

6. Removethecalibrationcuvette.

7. See Section 6.4 for the calibration verification information. Asummaryofthecalibrationerrorcodesisshowninthefollowingtable:

 E12: Problem: Standard Reading Incorrect 

Corrective Actions:

1. Clean Standard

2. Verify (13103410) Cuvette & programmed Calibration Value

3. Optical Problem: Contact Service

thx for replay jodiflo..i already do like section 11.2..now the problem..the calibration cannot be save..stil error 12 if i try to save calibration..fyi,the cuvette value is 335 μmol/L..and do u know how to factory reset?
