Service Codes are available and allow additional programming features. Following is a
listing of the available Service Codes and functions:
Set Reset Service code description
ALL LLA
This service code will enable the Ca
2+
value during auto-(9181 only)
matic serum/blood measurement. Special precautions are necessary
to obtain the correct Ca
2+
value due to sample exposure to room air.
CDC –
Clears all Service Codes.
9110: Except SLC.
DEC CED
Provides one additional digit of resolution for each measured
parameter for blood and serum samples. QC and Standard samples
are always displayed with high resolution. Urine samples are always
displayed in low resolution.
ECO OCE
Allows the operator to run the instrument in the economy mode. The
instrument will enter the STANDBY MODE. This occurs at the time
of the next 2-point calibration when no samples have been analyzed
since the last 2-point calibration.
FIF IFI
Allows printing of electrode voltages during printout of
measurements and calibrations. (not available for 9140)
LEM MEL
9180/9181 only!
This service code will print the last 20 error messages.
MGL LGM
This service code is available only in the model 9140/9180/9181
analyzer and enables Ca
2+
values to be displayed in mg/dL. The
normal mode displays values in mmol/L. QC and Standard results are
always displayed in mmol/L.
NOB BON
9180/9181 only!
This service code disables the beep.
QCC CCQ
When this code is enabled, QC values will be reported in direct ISE
measurement instead of flame-equivalent values. In this mode,
correlation factors are NOT applied to the measured values.
SFC –
9180/9181 only!
This code allows the input of a percentage for the ISE SnapPak
TM
counter.
SLC CLS
9110/9180/9181 only!
When this code is set, the current setting of the leasing counter, which
cannot be reset by the operator, is printed on the calibration report.
SSC CSS
9181 only!
This code toggles needle height to accommodate smaller (9181 only)
sample cups. In the default setting, the analyzer works with 2.0 mL
cups. To select 0.25 mL sample cups, SSC has to be activated. To
return to the default setting, CSS has to be activated.
CHP PHC
This code allows for the display and printout of pH results in
concentration of H
+
ions. The cH
+
will be shown in addition to the
pH value. cH
+
is not shown on QC values and statistics reports.
