Safety Guidelines

Caution!
Whenever it is likely that the protection has been impaired,
the device shall be made inoperative and secured against
unintended operation.
The protection is likely to be impaired if, for example:
• the device shows visible damage
• the device fails to perform the intended function
• prolonged storage at temperatures above 70 °C
• severe transport stresses
Before recommissioning the device, a professional routine
test must be performed. This test should be carried out at the
manufacturer´s factory.
Caution!
Take protective measures against ESD when the sensor socket
is open. At measuring temperatures from -20 to +100 °C the
temperature detector can be automatically identified.
The charging time of the battery may vary when a USB port with
lower power output is used. Temperatures above 50 °C may
result in loss of battery capacity.
