2 panel is an accurate wall mount and desktop data logger that displays and

records relative humidity, temperature and CO

Program ming

Most of the settings, such as memory clear, CO
sampling rate, pressure compensation and real time clock can all be changed using
the function keys.

Power Supply

2 panel uses 12VDC power adapter, which is included in the package.

The CO

USB stick connection

Recorded data can be easily downloaded to USB stick and save as *.XLS file. Easily
analyze the recorded data through the free software SW21 or through Excel.

Operation

POWER ON/OFF

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.

DAT E/T IME S ET UP

When device is powered on, hold down “SET” key for 2 seconds until entering device
setup mode. Press “UP” or “DOWN” key to select the program (P 50, displayed in
right-middle panel) and press “SET” key to enter.
First, choose the time format as 24 hour or 12 hour by press “UP” or “DOWN” key and
then press “SET” key to confirm. Now, start to input the real time clock value from
year, month, day, hour to minute. Press “UP” or “DOWN” key to adjust and the press
“SET” key to confirm.

After the date and time are set, a clearance of the memory must be performed. Press
“UP” or “Down” key to select P 10 and press “SET” key to enter P11. Press “UP” or
“Down” key to choose “YES” to clear previous memories and press “SET” to confirm.
Then, press “ESC” key twice to return to normal mode.

UNIT SET UP

Hold down “SET” key for 2 seconds until entering meter setup mode. Press “UP” or
“DOWN” key to select the program P 30 and press “SET” key to enter.
Press “UP” or “DOWN” key to select

°F or °C and the press “SET” key to confirm.

Press “ESC” key to return to normal mode.

TAKING MEASUREMENT

The device starts measurement when power on and update readings every second.

2 CONDITION INDICATOR

CO

The meter features light bar indicator to have user easily recognize the indoor air
quality. (See “Meter Setup” section for setting Normal & Poor threshold).

DATALOGGING

The meter can automatically record readings of CO

2/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.

MEMORY DOWNLOAD

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
SW21 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.

Meter Setup

Hold down “ SET” key for more than 2 seconds until entering setup mode. To exit
setup, press “ESC” to return to normal mode.

The available meter setup program are shown in below. Press “UP” or “DOWN”
key to select the program (P10, P20, P30, P40 or P50) in main menu and press “SET”
key to enter sub menu. Press “SET” key to select different sub menu (P11, P12, P13
or P14), programmable setting then flashes on panel. Press “UP” or “DOWN” key to
adjust and press “SET” to confirm. To leave without saving, press “ESC” key to return.

Hu midit y Calibratio n

This meter can be calibrated either via 35 % rH & via 80 % rH humidity standards.
The ambient condition is recommended as stable 25°C.

CAUTIO N:
Do not calibrate the humidity without the default humidity standards. Otherwise,

it will cause permanent damage. Contact Rotronic for humidity standards or
services.
Single point calibration will cause error code E11 or non accurate reading.
Always do dual point calibration to complete a process. Suggest starting calibration
from low humidity.

Pull out the humidity probe from panel

Before calibration, pull out the humidity probe from cover in panel rear side.

Calibration via humidity standards

Power on the device, plug the sensor probe into 35% humidity standard. Press “SET”
+”START”+”DOWN” keys simultaneously for 3 seconds to enter calibration mode.
Press “UP” or “DOWN” key to select 350 (35.0% calibration) and press “SET” to start.
“Calibrating value” (35.2% if at 25°C) is blinking on the LCD.

Waiting for 60 minutes to complete the 35% calibration. To quickly save, press “SET”
key any time. 800 (80.0% calibration) comes right after 35% calibration is done. Within
20 minutes, press “SET” key to start 80.0% calibration. “calibrating value” are blinking
on the LCD. Waiting for 60 minutes to complete the 80% calibration. To quickly save,
press “SET” key any time.

Now, the device is well calibrated. To abort without saving, press “ESC” to quit
without saving.

2 C a lib ratio n

CO

CAUTIO N:
Do not calibrate the meter in the air with unknown CO

2 concentration. Otherwise,

it will be wrongly calibrated and leads to inaccurate measurements.

The meter can be calibrated in fresh outdoor air (on sunny day) at 400 ppm CO2.
Besides the 400 ppm, the meter can also be calibrated at 0 ppm or any value under
990 ppm. The latest calibration point is treated as final and meter will ignore the
previous calibration data.

Before calibration, plug in the pipe of the ROTRONIC CO
CO

2-sensor on panel rear side and turn the CO2-Calibrator on.

Attention:
the cleanness of the CO

2-Calibrator air is 20...25 ppm.

Press “SET” +”START”+”DOWN” keys simultaneously for 3 seconds to enter
calibration mode. Press “UP” or “DOWN” key to select 400 (400 ppm) or 0 (0 ppm)
CO

2 calibration. 0 ppm function is only for 0ppm CO2 calibration. For other CO2 value,

please choose 400 ppm and press “SET” to enter. The default value is 400 ppm but
you can press “UP” or “DOWN” key to adjust the value from 5 to 990 ppm, it is 5 ppm
per step. Once choosing the calibration value, press SET to start and see “CAL” and

2 value blink on LCD.

Wait about 10 minutes until the blinking stops to indicate the calibration is completed.

To abort calibration without saving, press “ESC” at any time.
