Operating conditions
Temperature Temperature Temperature Temperature
Process temperature -5...+70°C / +23...+158°F
Ambient temperature -40…+65°C / -40…+149°F
Ambient temperatures below -25°C / -13°F may affect the readability of the
display.
It is recommended to protect the converter from external heat sources
such as direct sunlight because high temperatures reduce the lifecycle of
all electronic components.
