5. Connect the meter to the PC/laptop using the special USB Data cable (for Android use adapters) ==> meter will light up and be ON
6. On the software, press “Search Device” ==>
   ENV RD100 display might be empty, LED indication will remain active.
   ENV RD10 LED indication will remain active.
7. On the software, press “Start Recording ” ==> the measurement table and graph on the software will start accumulating the measurement results.
8. Press Mode button on the ENV RD100 , or change the mode switch on the RD10 to change modes of measurements between RF/LFM/LFE (RF Modulation and JONIT MODE are not supported).
9. On the software, press “Stop Recording ” ==> recording and logging will stop.
