D3 Slope Error: Thb - Bayer HealthCare RapidPoint 400 Series Service Manual

Message

D3 Slope Error: tHb

D3 Qualifier Descriptions
D3 occurs during calibration operations when the slope is outside the pre-
defined range for the indicated channel. A pH D3 error causes D3 for pCO
Slope errors are cleared by the next calibration if slope is within limits or the
channel is disabled through Setup. The channel returns to the calibration
state when the system completes a successful 1- or 2-point calibration that
clears D2, D3, or D4.

Probable Cause and Corrective Action
Service Solutions
Perform service solutions only after all other corrective
actions have been completed. If cartridge replacement does
not solve the problem:
1. Use the measurement cartridge simulator to perform the
sensor test.
2. Replace the connector block.
3. Replace the cartridge interface module.
The system turned the tHb parameter off because the CO-ox
module exceeded calibration limits.
1. Perform a full calibration.
2. If the parameter remains out of calibration, replace
the cartridges to make the parameter available for analysis.
Refer to Replacing the Measurement and Wash/Waste
Cartridges in Section 3 in the Rapidpoint 400 Series
Operator's Manual if you want to replace the cartridges.
3. If the message appears again, record the message and call
for technical assistance.
Service Solutions
Perform service solutions only after all other corrective
actions have been completed. If cartridge replacement does
not solve the problem:
1. Repeat full calibrations.
2. If the error continues, check valve alignment for the
measurement cartridge. Refer to Testing the Measurement
Cartridge Valve Alignment on page 244.
3. If the valve is out of alignment, replaced the cartridge
interface assembly.
4. Replace the measurement cartridge.
