Clean Cycle
This cycle is used to remove protein build-up from the ISE Module electrodes. The ISE Module positions
cleaning solution in front of the electrodes for a period of time which will allow the enzyme to remove
protein build-up on the electrodes.
Once this is done, the ISE Module is then flushed with Calibrant A. The Clean Cycle should be performed
once per 24-hour period.
We strongly recommend that a Calibration Cycle be run after a Clean Cycle. We also recommend that the
Clean Cycle be run at the end of the day to give the electrodes extra time to stabilize after the Clean
Cycle. This is not required. However, users will experience slightly better performance if they give the
electrodes some time to stabilize after the Clean Cycle. It is also recommended that high volume users run
a Clean Cycle after every 50 serum samples.
Purge A Cycle
This cycle is used to purge Calibrant A solution through the tubing from the reagent kit to the ISE Module.
The ISE Module pumps Calibrant A from the reagent kit through the ISE Module to wash out the flow path.
Purge B Cycle
This cycle is used to purge Calibrant B solution through the tubing from the reagent kit to the ISE Module.
The ISE Module pumps Calibrant B from the reagent kit through the ISE Module to wash out the flow path.
Sip Cycle
Every 30 minutes after the last sample is run, the ISE Module will automatically run a Sip Cycle. The Sip
Cycle is used to keep the calibrants in the tubing fresh, and to refresh the Calibrant A in front of the
electrodes.
Off Cycle (Under Electrode replacement command)
This cycle is used to clear fluid from the flow path of the ISE Module, and to pause the Sip Cycle. The ISE
Module then runs the waste pump until the electrode flow path is cleared of fluid.
Warning: This cycle is required before any electrode(s) is removed from the ISE Module. Failing to
run this cycle will cause the fluid in the flow path to leak when electrodes are removed.
Spilled fluid (or electrodes that are wet on the outside) can cause sporadic and/or erroneous results.
Always dry each electrode when changing electrodes.
It should be noted that every 30 min
utes, a Sip Cycle is initiated, and 100 μL of Calibrant A is dispensed. If
the electrodes are removed without initiating a Maintenance Cycle, a Sip Cycle may occur and the 100 μL
