Operation - Vector TOA-T101 Quick Start Manual

Operation

The device is preconfigured according to the enclosed documentation. Settings such as switching on and switching off
temperature limits can be adjusted. The OPA-S operating/programming unit is used for configuration. This can also be
used to display the measured values (see section "TOA Configuration", page 8).
