CHECK ELECTRODES
This message is displayed when either of the following conditions are present.
1.
More than six aspirations of Standard A are required for all electrode
channels.
2.
The difference between voltage A and B is out of specification for all
channels.
Possible causes and remedies:
•
Electrodes are not plugged in. Check the slide mechanism to ensure it is in
the correct position and firmly pushed into electrode connectors.
•
Perform Daily Maintenance.
•
Check or replace reference electrode.
•
Replace
ISE SnapPak
TM
.
NA NOT CAL’D
K NOT CAL’D
CL NOT CAL’D
CA NOT CAL’D
LI NOT CAL’D
These messages will be displayed when a specific electrode does not calibrate
properly during a calibration sequence. If more than six standard draws are
required or the difference between Standard A and Standard B voltages is out of
range, the
NOT CALIBRATED
message will be displayed for each channel
which exhibits either of these conditions. A copy of the calibration report should be
printed to provide the electrode output voltages measured during calibration.
The electrode voltage range table identifies correct voltage ranges for each
electrode parameter.
If the difference between Standard A and Standard C (9180/9181 only) is out of
range for Li
+
or Na
+
,
LI NOT CAL’D
will be displayed.
Possible causes and remedies:
•
Check to ensure calibration reagents are transported correctly. Test for
leaks, blockages, bubbles, or improper pump flow rate.
•
Check or replace
ISE SnapPak
TM
.
•
Check whether electrodes are plugged in properly. Check the slide
mechanism to ensure it is in the correct position and firmly pushed into
electrode connectors. Clean and/or replace electrode.
•
If A-C is out of range for Na
+
, repeat the calibration or replace the
ISE SnapPak
TM
.
•
Check or replace SBC Card.
