CO2METER COM TIM10 CO2 Temperature and Humidity Monitor Instructions

TIM10 CO2 Temperature and Humidity Monitor
Instruction Manual

INTRODUCTION

Thank you for purchasing this desktop CO2 monitor. It measures carbon dioxide levels, air temperature and humidity. This makes it ideal for indoor air quality (IAQ) diagnosis  and HVAC system performance verification.
Poor indoor air quality is considered unhealthy. It can lead to drowsiness, inability to concentrate, and even illness (for example, Sick Building Syndrome).
IAQ monitoring of CO2 levels is widely used in public areas such as offices, classrooms, factories, hospitals and hotels. It is also recommended for industrial hygiene in some  countries. (See appendix).

Product Features:

• Large display shows CO2 level, temperature, humidity, date and time
• 15 degree tilt angle makes the display easy to see and read
• Indoor air quality level indication: Good, Normal, and Poor
• Stable NDIR sensor for CO2 detection
• Visible and audible CO2 warning alarm
• ABC (Automatic Baseline Calibration) or manual CO2 calibration
• Maximum or minimum CO2 level recall function

MATERIALS SUPPLIED

This package contains:

• Meter
• Power Supply (5V +/- 10%, >= 0.5A)

OPERATION

POWER ON/OFF
Plug the wall adaptor into an appropriate receptacle. The meter will turn on automatically after a short beep. The lit LED indicates full power.
If the voltage is too high or low, “bAt” will display on the LCD and the LED will flash. Please see page 14 for trouble shooting.
During normal operation, the LCD will display the current CO2 level in ppm, air quality level, air temperature, humidity, and the current date and time (Fig.1).

TAKING MEASUREMENTS
The meter starts taking measurements immediately after it is turned on and updates the readings every second. In the event the operating environment is quickly changed (for  example, from high to low temperature), it will take approximately 2 minutes for the CO2 and temperature to adjust and 10 minutes for humidity to stabilize.
NOTE: Do not hold the meter close to your face as your breath will affect the CO2 level.

MIN/MAX
While the meter is powered on, press the “MIN/MAX▼“ button to see the minimum and maximum CO2 level, temperature, and humidity in turn. Each press of “MIN/MAX▼“ will display the MIN and MAX values in order, then return the meter to normal mode (Fig.2).
During normal operation or while viewing MIN/MAX levels, press and hold the “RESET“ key for more than 1 second to clear the stored minimum and maximum values.

HIGH CO2 ALARM

ALARM
The meter features an audible alarm that warns the user when the CO2 concentration exceeds the programmed limit. Users can set 2 limits: a CO2 level that requires ventilation  (See P1.3 in setup for setting alarm limits) and a lower CO2 level when ventilation is no longer required (See P1.2 in setup CO2 normal limit).
During high alarm, the meter emits an 80dB beep and displays the fan icon on the LCD. The alarm can be temporarily stopped by pressing any button, or it will automatically  stop when the CO2 level falls below the lower limit.
If the alarm is temporarily silenced, it will resume if the CO2 level fall below the lower limit then rises above the upper limit again, or if the “RESET“ button is pressed to re- activate the alarm.
The fan icon remains flashing even if the beeps are silenced. The icon only stops flashing when the CO2 level fall below the lower limit (Fig.3)

SETUP

There are 4 setup modes: P1-CO2 alarm levels, P2-temperature (C or F), P3-date/time, and P4-factory reset. When you press “SET” the setup mode will be shown in the lower  right corner of the screen.
To enter setup, while in normal mode, hold down the “SET“ button for 3 seconds. To exit setup, press “ESC“ while P1.0, P2.0, P3.0, or P4.0 is displayed.
P1.1 SET CO2 GOOD LEVEL
Press “SET“ to display P1.0 and ”CO2” (Fig.4) on the LCD. Press “SET“ again to set the CO2 GOOD level. The current set value will be blinking on LCD (Fig.5).

Press “▲“ to increase or “MIN/MAX▼“ to decrease the value. The GOOD alarm range is from 0 to 700ppm in 100ppm increments. Once the preferred CO2 level is  selected, press ”SET“ to continue on to P1.2 to set the NORMAL level (Fig.6 ) or press “ESC“ to return to P1.0 without saving changes.
P1.2 SET CO2 NORMAL LEVEL
P1.2 is the upper limit of the CO2 NORMAL level.
The current value will flash on the LCD (Fig.6).
Press “▲“ to increase or “MIN/MAX▼” to decrease the value. The NORMAL level can be set between 700 and 1,000ppm. Once the preferred value is selected, press ”SET“  to save P1.2 and continue onto set the P1.3 POOR + ALARM threshold setting (Fig.7) or press “ESC“ to return to P1.0 without saving changes.

P1.3 SET CO2 POOR LEVEL + ALARM
P1.3 is used to set the CO2 alarm threshold. The current set value will blink on the LCD (Fig.7). Press “▲“ to increase or “MIN/MAX▼“ to decrease the value. The POOR  level can be set between 1,000 to 5,000ppm. Press “SET “ to confirm P1.3 and continue to P1.4 (Fig.8) or press “ESC“ without saving to return to P1.0

P1.4 SET ALARM ON/OFF
P1.4 is used to set alarm on and off. When entering P1.4, the default “On“ will be blinking on the LCD (Fig.8).

CO2 CALIBRATION

The meter is calibrated at 400 ppm (parts-per-million) CO2 concentration at the factory. 400 ppm is comparable to fresh outdoor air.
There are 2 types of calibration available: ABC (Automatic Baseline Calibration) or manual calibration. One or the other should be used regularly to maintain good accuracy.
Note:
If TIM10 accuracy becomes a concern after long use or other special conditions, return the meter to the dealer for calibration.
CAUTION:
Do not calibrate the meter with air or bottled gas that contains an unknown CO2 level. The meter will assume it is 400 ppm CO2 and will give inaccurate measurements.

ABC Calibration
ABC (Automatic Baseline Calibration) is designed to eliminate the zero drift over time of the infrared CO2 sensor. The ABC function is enabled by default from the factory.
For ABC to work properly, the meter must continuously monitor CO2 levels for at least 7.5 days (power on). During that time, it will record the lowest CO2 level and set that as  the 400 ppm baseline for future readings. Therefore, it is critical when using ABC calibration that the meter be exposed to fresh air at least once every 7.5 days. If this is not  possible, then manual calibration is recommended.

Manual Calibration
Manual calibration requires fresh, dry outdoor air when CO2 levels are approximately 400 ppm. Do not calibrate during rainy days. High humidity will affect the CO2 levels in  air.
During manual calibration, avoid placing the meter in areas crowded with people or close to structures that might give off CO2 like air ventilation pipes, chimneys, or  automobiles.
To manually calibrate the meter, place it outdoors, and turn it on for at least 2 minutes. Then hold down “SET“ ,”▲” and “MIN/MAX▼” simultaneously more than 1 second  to enter CO2 calibration mode (Fig.17). 400 ppm and

“CO2” will blink during calibration.
Wait about 5 minutes until the blinking stops.
Calibration is completed automatically. To stop manual calibration, press “RESET“ for at least 1 second.

Note:
Keep the meter away from any animals, humans or plants which might affect the CO2 concentration nearby during the calibration.

RH CALIBRATION

This humidity accuracy of this desktop CO2 meter is set at the factory, and cannot be re-calibrated.
