Comfort Chek 100/200 1.0 INTRODUCTION 1.1 General Bacharach’s line of CO2 Analyzers are easy to use, but it is essential that these Operating Instructions be read and understood by all operators and maintenance personnel prior to using or servicing the instrument.
Comfort Chek 100/200 1.
Comfort Chek 100/200 2.0 OPERATION 2.1 Important Note Always ensure that the instrument’s gas inlet (Figure 1, Item A) and gas outlet (Figure 1, Item B) are unobstructed and open to the atmosphere. Be careful not to breath directly on the instrument while taking a measurement; otherwise, inaccurate readings will result. 2.2 Switching the Instrument ON/OFF Switch ON the instrument by momentarily pressing the button.
Comfort Chek 100/200 2.3 Pump Operation (Model 200) With the instrument already switched ON, momentarily pressing the button will start and stop the internal pump. The optional Extended Probe Assembly with in-line filter (P/N 0019-3310) can be connected to the gas inlet fitting (Figure 1, Item A) on the top of the instrument for drawing in gas samples from hard-to-reach areas. If desired, a section of 1/8" I.D.
Comfort Chek 100/200 Each time the f3 button is pressed, the display scrolls through the following measurements: CO2 ppm 340 Carbon Monoxide (Model 200) CO ppm 0 , Temp F 72.4 Baro"Hg 28.79 RH % 45 2.6 Carbon Dioxide (Models 100 & 200) Temperature (Models 100 & 200) Barometeric Pressure (Models 100 & 200) Relative Humidity (Models 100 & 200) Current / Peak Reading Mode The instrument can display either the current readings of all measurements, or peak gas readings.
Comfort Chek 100/200 2.7 Storing Readings There are two storage modes available: • Snapshot • Continuous Data Logging Pressing the f1 button once stores (takes a snapshot of) the reading shown on the display. Clock icon is displayed once for a snapshot, and flashes during continuous logging. CO2 ppm 340 Pressing and holding down the f1 button for at least 3 seconds starts the continuous data logging of the readings at a preset interval (factory set at 15 minutes).
Comfort Chek 100/200 2.9 Battery Charge Display An indication of the battery’s charge level is obtained by pressing the f2 button once. A bar graph in the lower part of this screen shows an approximation of the battery’s remaining charge. As the charge reduces, the bar graph decreases in size. Typical operating time from a full charge is approximately 10 hours. Battery Level = represents full charge = represents low charge 2.
Comfort Chek 100/200 3.0 MAINTENANCE 3.1 Cleaning Keep the instrument clean by wiping it with a soft cloth dampened with a mild detergent solution. 3.2 Sunlight The unit should not be left out in direct sunlight, or in other areas where excessive heat exists, for long periods since component damage due to overheating may result. 3.3 Servicing There are no user-serviceable parts inside the instrument. Unauthorized disassembly of the unit will invalidate the warranty. 3.
Comfort Chek 100/200 Release the f2 button and perform an Air Calibration as described in Section 3.7 WARNING! Failure to perform an Air Calibration after resetting the instrument to its factory settings may cause incorrect gas readings to be displayed. 3.6 Battery Charging When the ‘BattLow’ message is displayed (refer to Section 2.8), the instrument must be recharged using the supplied battery charger.
Comfort Chek 100/200 3.7 Zeroing the Gas Sensor(s) Zeroing the gas sensor(s) consists of performing an Air Calibration in fresh outside air, which sets the CO2 sensor to read 340 ppm (Models 100 and 200) and the CO sensor to 0 ppm (Model 200 only). Important! It is essential to ensure that the instrument is in fresh air before attempting an Air Calibration. If this condition is not ensured, incorrect gas readings will occur.
Comfort Chek 100/200 3.8 Removing the Temperature & Humidity Sensor Probe If desired, the Temperature & Humidity Sensor Probe (Figure 1, Item D) can be removed and the instrument used to primarily measure just gas. Important! With the probe removed, the temperature and humidity readings should be disregarded. All other readings are valid. Note: If the probe is reinstalled with the instrument switched ON, observe that ‘BattLow’ may briefly appear even with a fully charged battery.
