7.2.2.1 Sipper Pump
Home
Touch the [Home] button to Home the sipper pump plunger. The pump plunger will extend fully, then retract slightly.
Aspirate
Touch the [Aspirate] button. The pump plunger will retract about half way as it does when it aspirates a sample. Note that
the actual distance depends on the sample size setting.
Dispense
Touch the [Dispense] button. The pump plunger will extend about half way as it does when it dispenses a sample into the
sample module.
When you have finished testing the sipper pump, touch the [X] button to return to the main display.
7.2.2.2 Buffer Pumps
Touch the [ON] button under a buffer pump. The selected buffer pump will run. Touch the [OFF] button to stop the pump.
When you have finished testing the buffer pumps, touch the [X] button to return to the main display.
7.2.2.3 Calibrator Pumps
Touch the [ON] button under a Cal Pump. The selected calibrator pump will run. Touch the [OFF] button under the same
pump to stop it.
NOTE: Prime all installed calibrator bottles daily to remove air bubbles from the tubing and deliver fresh
calibrator to the cal wells!
When you have finished priming the fluid pumps, touch the [X] button to return to the Main display.
7.2.3 Modules
From the Service menu, touch the [Modules] tab.
The Modules tab displays the status of the probes, probe current for each enzyme probe, voltage for each ISE, and the
temperature. The probe current is expressed in nA (nanoamperes, 10
-9
amperes), a very low level of electrical current.
7.2.3.1 Flush
Touch the [Flush] button under Module 1 to flush the sample module with buffer. Observe the probe current values
(baseline). If they are above 6 nA, check to see if they are decreasing in value. Check the sample module; it should be full
of buffer. If necessary, touch the [Flush] key to flush the sample module again. Note that when the instrument is first
powered up, it may take several hours for the baseline currents to drop below 6 nA.
Touch the [Flush] button under Module 3 to flush the sample module with ISE buffer. Note that the instrument will purge
buffer to waste if the incorrect buffer is in the line.
Observe the ISE voltage values. They should be between -40 and 60mV and stable. When the instrument is first powered
up, it may take an hour for the voltages to stabilize.
