6.13 Temperature sensor
The ESYSTA
®
BT Pen is equipped with a temperature sensor that regularly
measures the ambient temperature and indicates the results on the display.
Extreme ambient temperatures can reduce the effectiveness of the insulin or
even render it ineffective.
If the temperature range above 40 °C is exceeded, the message “Ht” (“High
temperature") appears in the display. If the temperature falls below around
2 °C, the message “Lt” (“Low temperature") appears in the display. In these
instances, it should be assumed that the insulin will no longer have an adequate
effect. We therefore recommend switching to a new insulin cartridge that has
been stored in the temperature range specified by the insulin manufacturer.
An injection can still be carried out by adjusting the selected dose. When the
selected insulin units are set, the warning message disappears and reappears
next time the pen is switched on. When the insulin cartridge is changed,
including a new adapter, the temperature warning display is reset.
Note:
Please note that the temperature sensor has a certain tolerance range and the
values stated above are only guideline figures. Please also regularly check the
storage and usage temperatures for your insulin with the insulin manufacturer.
Information from the temperature sensor is also transferred to the ESYSTA
®
App and the ESYSTA
®
Portal.
