ST-200 aQua

Operator’s Manual

82

C A K LOW, DRIFT message may indicate that the block 1 needs replacing.

Before doing so, perform a daily cleaning cycle, as described under

DAILY CLEANER. Next, perform a calibration. If the potassium

calibration value remains low, replace block.

D A LOW, DRIFT message for chloride or Ionized Calcium only, may

indicate that replacement of the particular block is necessary. Before

doing so, try performing a daily Cleaning, as described under DAILY

CLEANER. Next, perform a calibration. If the calibration value remains

low, replace the particular electrode block.

E If all parameters have low or high calibration values, the problem is

most likely with the electrode assembly or the reference electrode (on

the Na/K/iCa/Cl/Li/pH analyzer, the problem may be the disposable

reference electrode). It is also possible that an incorrect reagent pack

is being used, the ST-200 aQua will not calibrate successfully.

F

If drift messages appear for all parameters, there is most likely a flow

problem (refer to flow problems) or electrode stack assembly problem

(refer to electrode stack assembly). Also, inspect the electrode blocks

pins, including the reference electrode pin, to ensure that they are dry

and clean. After reassembly, the analyzer should be primed and

calibrated.

D. Reagent Pack

AIR IN CAL A, AIR IN CAL B, REAGENT PACK LOW, INSUFFICIENT PACK

PLEASE REPLACE & EMPTY PACK PLEASE REPLACE messages may

indicate that the reagent pack is empty or low.

The ST-200 aQua has an RFID (Radio Frequency Identification System)

which keeps track of the reagent pack usage. The ST-200 aQua will

indicate the availability of reagents in a decreasing manner i.e., 100% to

0% at every analysis.

When 10-15% of the reagent pack has remained in the reagent pack,

instrument will indicate INSUFFICIENT PACK PLEASE REPLACE till it

reaches 5%. Below 5% the instrument will displays EMPTY PACK PLEASE

REPLACE.

E. Bubble Detector

The bubble detector detects the difference between liquid and air, which is

important for proper sample positioning in the ST-200 aQua. It consists

the flow cell at the top to drop the sample by the pipette. To verify

performance, proceed to *DIAGNOSTICS* followed by sub menu

HARDWARE and perform SAMPLE DETECTOR test.

In sample detector test, if liquid or air is not detected, clean the Bubble

detector with diluted Sodium Hypochlorite (NaClO) or Daily cleaner or de-

ionized water. Then also if not solved, replace bubble detector.
