5.1 Switch on the device

When the CO2 monitor is off, press and hold the on/off key for 3 seconds to turn on the meter.

5.2 Switch off the device

When the power is on, press the on/off key for 3 seconds to switch off the meter.

5.3 Toggle view

When the unit is switched on, all measured values are displayed as numerical values.
Furthermore, the CO2 meter shows the air quality status in a green-yellow-red status lamp.
Use the arrow keys (left / right) to switch to the graph. The graph shows the course of the CO2
content of the last 5 h after switching on.

5.4 CO2 traffic light function

The CO2 monitor has a status lamp display (CO2 traffic light). The limit values for colour changes
are as follows:

5.5 Settings

Press the on/off key twice in quick succession to open the settings menu .

5.5.1 Setting the date (DATE)

Use the left and right keys to change the highlighted value for day, month, year. Confirm the
setting with the on/off key.

5.5.2 Setting the time (TIME)

Use the left and right keys to change the highlighted numeric value for hour and minute. Confirm
the setting with the on/off key.

5.5.3 Select unit (UNIT)

You can switch between °C and °F using the left and right keys. Confirm the setting with the on/off
key.

5.5.4 Set temperature offset (TEMP)

To set an offset for the measured temperature value, use the left and right keys to change the
numerical value. Confirm the setting with the on/off key.

5.6 Automatic calibration

The PCE-CMM 5 has the integrated self-correcting ABC algorithm (Automatic Baseline
Correction) for automatic adjustment of the baseline value. This calibration is performed once a
day.
For this, the PCE-CMM 5 requires a regular supply of fresh air. The measured value is adjusted
automatically.
The ABC function is permanently switched on (cannot be switched off) and adjusts the baseline
value at regular intervals when the CO2 level is low. Do not use this meter in a closed environment
where the CO2 concentration remains relatively high. This would adversely affect the self­correction of the meter.

5.7 Charge the meter

When the battery icon on the display indicates that the battery is discharged, the PCE-CMM 5
must be charged via the micro USB port. To do this, use the supplied USB charging cable or a
USB power supply with 5 V / 1000 mA. Please note that it may take at least 2 hours to recharge
the battery to 100 %.
Note: Charging via a 500 mA port on the computer is not possible.

7 Disposal

For the disposal of batteries in the EU, the 2006/66/EC directive of the European Parliament
applies. Due to the contained pollutants, batteries must not be disposed of as household waste.
They must be given to collection points designed for that purpose.

In order to comply with the EU directive 2012/19/EU we take our devices back. We either re-use
them or give them to a recycling company which disposes of the devices in line with law.

For countries outside the EU, batteries and devices should be disposed of in accordance with
your local waste regulations.

If you have any questions, please contact PCE Instruments.
