6.8 Temperature sensor has been removed
The temperature sensor TNo. has been removed. Confirm this with OK. If you have not removed the
sensor, the cause is most probably a sensor defect. Please check this and swap the sensor, if needs
be!
TNo. stands for temperature channel T1 or T2, depending on which temperature channel is concerned.
6.9 Critical error A
Error message: Critical error
A critical error (1) has been detected in the device settings; these will be reset to factory
settings. Once you have switched the device off and on again, you can continue working.
Check the settings (e.g. date, time, alarm limits).
Follow the instructions! It is imperative that the settings of the device are checked!
Cause: RAM error
6.10 Critical error B
Error message: Critical error
A critical error (error number) has arisen. The device will no longer work. Please switch
the device off.
Error in the power supply: 3.3 V incorrect
Error in the power supply: 6 V incorrect
Error in the system ADC. A monitoring of the device operation is not guaranteed.
The device-specific settings are not consistent.
The process for RAM monitoring is not working properly.
The process for determining the oxygen partial pressure is not working correctly.
Note: It is imperative to note down the error number before switching the device off. The most probable
cause is a fault in the power supply of the device. If the error is in direct conjunction with an external
event, such as the device has dropped, defibrillation of the patient, et cetera, the device has to be
switched on and off again. If the error has disappeared, continue to operation of the device. If the
error occurs again, switch the unit off and contact manufacturer.
6.11 Internal error – analogue output
Internal defect in chosen analogue output. Use other analogue output if needed.
Here the user cannot use the selected analogue output. A continuation of the logger operation without the
use of the analogue output concerned is possible at any time. The fault can be remedied by the after-sales
service department only.
6.12 Defective fuses
The MPR2 has been equipped with a safety fuse. If the fuse is defective, the MPR2 is no longer operational.
The fuse is accessible when the cover to the battery-pack compartment is open.
When the battery pack compartment is open, there is no protection against penetrating liquids!
The fuse may be replaced by trained staff only. If the apparatus does not operate after the first
replacement, remove the fuse again and take the apparatus to the after-sales service department
for repair.
The MPR2 must not be operated when the battery-pack compartment is open!
Prior to closing the battery-pack compartment, check the seal. If it is damaged, it has to be
replaced by a new one.
