1. Turn the meter ON.
2. The meter must be started at least 1 minute prior to deployment and data logging to allow the CO2 sensor
time to warm‐up and calibrate.
3. Set the logging interval as desired and commence logging by depressing the “Log” button on the right side
of the meter.
4. When data logging is completed, turn the “Log” OFF.

Setup
CO2Meter, Inc.’s sampling meters will require minimal setup since they are designed to be portable. The most
important aspect of the setup involves connecting the sampling hoses and ensuring proper setup. The
Instrument
Overview
section on page 8 shows the labeled components of these meters, as referenced throughout the rest of
this manual.
Data
Logger
Models
These models feature an internal memory capable of storing data when not connected to a computer. These units
will allow you to simultaneously read and store CO2 concentration level data. Due to the nature of their design,
these units should be connected to your computer first, before operation, in order to initialize and set the logging
interval and real‐time clock.
Insert four (4) AA size batteries into this unit or connect the unit to the included power supply. In order to initialize
data logging functionality, the unit MUST be connected to the computer with data logging switched to OFF, and the

software started. Once the unit has been connected, click on the “Configure Sensor” button in the GasLab
®
interface, set the data logging interval and pump periods as desired. We recommend leaving the pump interval to
the default 10‐second period. For the pump period, we recommend 10 or more seconds.
The pump PWM period can also be adjusted for advanced applications, with 1 being full duty cycle, and values
approaching 255 being the shortest duty cycle. The pump mode should always be set to “Data logging” for proper
operation of the unit.
All models have an internal coin cell CR‐2032 3V battery backup for the real‐time clock. This battery is inserted in
the factory for your convenience and should last the lifetime of the product.

Here you can change the brightness and color theme (3 available) on the device and you can also activate a Screen
Timeout to save power. This setting will not affect the meter’s functionality but will affect the battery life
depending on how you set this parameter.
