  • Page 16: Operation Modes

    6.4 Operation modes 6.4.1 DM – single distance measurement LAM71 performs one measurement and then waits for new commands. The duration of the measurement depends on the number of preset measuring values SA and the pre- set measuring frequency MF.

  • Page 17: Status

    Query: Example: TP 048.4 The user of the LAM71 must make sure that the stated ambient temperature (operating tempera- ture) is adhered to. In case of deviations below or above the temperature range no measurement is possible. The LAM71 will send an error message.
