Rotronic HL-1D Quick Manual

Quick guide for Rotronic HL-1D data logger
Congratulations with your new Rotronic HL-1D logger for measurement of relative humidity and
temperature. For your comfort we have gathered some of the frequently asked questions in this small
quick guide.

Battery

In your package there is a CR2 battery for your device. Use a coin to open/close the battery cover on the
back side of the logger and install the battery in the battery slot.
The battery has a life expectancy up to 3 years, but in the end of the battery lifetime the logger might
show incorrect data due to limited power. It is recommended to change the battery after 1.5 years (or
less depending on climate conditions, battery type, and frequency of use).
On or Off
Turn on: press the "Start/Stop" shortly - your logger is now in "view mode".
Turn off: press the "Start/Stop" shortly - your logger is now off (only possible when not in LOG mode)

Logging (LOG mode)

Start logging: Press the "Start/Stop" for 3 seconds - your logger is now in data logging mode/LOG mode
(The "LOG" symbol is visible when activated)
Stop logging: Press the "Start/Stop" for 3 seconds - your logger is now in "view mode", but your data is
saved on the device

Green and Red lamp (in LOG mode only)
