Once the 12VDC power adaptor is connected, the device will be automatically powered on. At power on, it performs 30 seconds countdown for device warm up, then enters normal mode with real time clock displayed. To power off, unplug the power adaptor.
The device starts measurement when power on and update readings every second.
The meter features light bar indicator to have user easily recognize the indoor air quality. (See “Meter Setup” section for setting Normal & Poor threshold).
The meter can automatically record readings of CO2/TEMP./RH for long time environment monitoring. The memory capacity is 6000 points for each parameter. Users can set up sampling rate from 1 minute to 12 hours and 59 minutes. The factory default rate is 1 minute.
First, setup the data record mode you need. Hold down “SET” key for 2 seconds until entering meter setup mode. Press “UP” or “DOWN” key to select the program P 10 and press “SET” key twice to enter P12. In P12, select the data record mode as "STOP" or "LOOP". Press "UP" or "DOWN" key to select and then press "SET" to confirm.
"STOP": The device stops logging while the memory space is full.
"LOOP": After the memory is full, it starts to overwrite the oldest data.
Second, setup the sampling rate. Once finishing the P12 and press “SET” key, it enters P13. Press “UP” or “DOWN” key to adjust the sample rate from hour to minute and press “SET” key to confirm. Press “ESC” key to return to normal mode. After sampling rate setting and data record mode are completed, press “ START” key for 2 seconds under normal mode to start logging. The “REC” LED turn into green and flash on panel to indicate the logging is in process.
To terminate data logging, press “ ESC” key for 2 seconds and green LED light vanish. Repeat above to start another run of logging. If the data record mode is programmed as "STOP", "REC" LED turn into red color and flash while the logging memory space is full.
The meter features logged memory download function by using a USB stick instead of connecting it with a computer. Before download, press “ESC” key for 2 seconds to stop the logging. Plug USB stick (max. 8GB memory) to USB slot on device left side, hold down “DOWN” for more than 2 seconds until seeing " USb” appears on panel and then “USb” starts flashing on panel to indicate the downloading is in process. It will take minutes to fully download the memory. The data downloading time depends
on memory size and USB stick.
The download data is saved as *.XLS file in USB stick. Using free Rotronic software HygroSoft or Excel to analyze the data. Suggest formatting your USB stick as FAT32 before using. If error code E60 ~ E65 appears on panel, suggest trying another model of USB memory stick.
Attention: In some cases when the size of the logged memory is large, it can happen that the display shows an error code (E60 - E65). Check the USB memory stick, the data transfer usually works. If not, repeat the process.
