Operation

On / off

On
To switch on the meter when it is switched off, press and hold the center key for about 3 seconds. The meter starts with a 120-second warm-up phase.

Off
To switch off the meter when it is switched on, press and hold the center key for approx. 3 seconds.

Temperature
Press and release the key to switch between the temperature units °C and °F.

Alarm
When 1000 ppm of CO2 is reached, the unit switches to alarm mode.
This is indicated by means of an acoustic and a visual alarm.

Visual alarm:
The display background flashes red every second.

Audible alarm:
The beep sounds every second. To switch the acoustic warning off or on, press and hold the key for about 3 seconds.

Measurement mode
Press the MODE key to switch between the different measurement modes. (see 2.4) Press and hold the MODE key to delete the minimum, maximum and average values.

Backlight
When the meter is switched on, press the central key to switch the backlight on or off.

Automatic power-off
The unit switches off after 2 hours of inactivity (no operation by pressing a key) in battery mode.
This function is not active during mains operation. The unit then remains permanently switched on.

Charging the battery
Fully charge the device using the USB cable supplied before using it for the first time.
Recharge the device when the battery status indicator shows the flat battery icon .
For example, use a USB plug-in mains adaptor (not included) with at least 1 A output power or use a USB port on a PC that provides this power.

Date / time

To set the date and time, press and hold the + keys simultaneously when the meter is turned off until the display switches on.
Press the key twice. The year flashes.
Use the keys and MODE to set the current year.
Press the key.
Use the keys and MODE to set the current month.
Press the key.
Use the and MODE keys to set the current day.

Calibration

The unit was calibrated at the factory. If there are noticeable deviations in the measured values, you can recalibrate the unit.
Two options are available for calibration.

Automatic calibration
The PCE-CMM 10 has an integrated self-correcting ABC (Automatic Baseline Correction) algorithm for automatic adjustment of the base value.
To calibrate the meter, place it in an environment with fresh air for 3 days when it is switched on. (The best result is achieved outside buildings) Connect the instrument to an external power source for calibration.
The measured value is automatically adjusted.

The ABC function is permanently switched on and adjusts the base value at regular intervals in case of low CO2 pollution.
Do not use this meter in a closed environment where the CO2 concentration remains relatively high. This would negatively affect the self-correction of the device.

Manual calibration
Place the switched-on unit in an environment with fresh air for 20 minutes.
(The best results are achieved outside buildings)
When the meter is switched on, press and hold the MODE keys until the icon appears on the display. The calibration takes about 10 minutes. Afterward, the instrument returns to measurement mode.
