PASS:
230V ± 10.0%
115V ± 10.0%
31.8 Temperature check: Heating system zones
The temperature validation is performed using a thermometer with a sensor suitable for
measuring temperature on a stainless steel surface with a resolution of 0.1 °C as a
minimum. Tape the sensor is placed in the middle position of the heating zone. Make sure
that the tape keeps the sensor in complete contact with the surface area.
Taping on the sensors is an in-optimal procedure as the tape itself will insulate
from the airflows and thus not represent an entirely perfect picture. It is, however,
a usable compromise if the size of the taped area is kept small and the tape used is
strong, thin and light.
Place the sensor on each zone and verify the temperature. For temperature validation in
the MIRI
®
compartments, tape the sensor in the middle of the compartment and/or lid.
PASS: all temperatures measured on the bottom of the compartments where the
dishes are located must not deviate more than ± 0.2 °C from the setpoint.
If calibration is needed, please refer to the "12.5.1 Temperature sub-menu" section for
more information on how to perform the temperature calibration.
An iterative process may be needed if differences in the temperature levels are
found and compensated through the calibration procedures. Bottom and lid
temperatures will affect each other to some extent. There will be no crossover heat
noticeable between compartments.
31.9 6-hour stability test
Following the careful validation of the single parameter, a 6-hour (minimum duration)
check must be initiated.
The device must be set up as closely as the condition under which it will be running in
clinical use.
Make sure that the Esco Medical data logger software is running.
Check that parameter are logged and give a meaningful reading. Let the device run
without interfering for at least 6 hours. Then, analyze the results on the graphs.
Pass I:
Internal sensor temperature variation from set point is within ± 0.1 °C absolute.
