- The specifications given are valid for an ambient temperature range between 0 and + 40°C
- If measured values only deviate slightly from specification, clean fester sockets, plugs and measuring cables, then repeat check. Before replacing components, check wiring and connections, particularly in cases where the specification is less than 10 Ohms, repeat the resistance measurement on the component
