Once the changes have been made, click on the SETUP button to save them. Press the DEFAULT button to set the
RHT10 back to factory default conditions. Press the CANCEL button to abort the setup.
Note: Any stored data will be permanently erased when the user clicks on Setup. To save the data before creating
a new setup, click Cancel and then download the data.
Note: The battery may run out before the RHT10 has finished collecting a specified number of sample points.
Always ensure that the remaining charge in the battery is sufficient to last the complete duration of your
logging exercise. When in doubt, we recommend that you always install a fresh battery before logging
critical data.
If INSTANT was selected in the SETUP window, the RHT10 begins logging at the instant the SETUP button is
pressed. If MANUAL was selected, the RHT10 must be manually started by pressing and holding the device’s
yellow button for approx. 3 seconds, or until the two LEDs on the RHT10 flash at the same time.
Logging will continue at the programmed sample rate until the number of readings (sample points) specified in the
Setup window is reached.
The green LED flashes once per sample point and the red or yellow LED flashes when user programmed alarm
limits are exceeded. For details, see LED status guide.
