Short Operating Instructions Dräger FG4200
General safety instructions
Any use of the FG4200 requires full understanding and compliance with the operating
instructions 5695051, the relevant standards, as well as the relevant statutory regulations.
The device is intended only for the uses described in this manual. Any improper use of the device may lead to
electric shock or destruction of the measuring instrument!
Before using the measuring device for the first time, the integrity of all components must be checked, e.g.:
Device exhibits no visible damage
No condensed water in the gas preconditioner
The gas preconditioner filter is clean
Gas hoses without defects
Visual inspection of the probe
Always fully charge the FG4200 via the USB interface with a 5 V DC / 1 A USB power supply
adapter only.
Incomplete charging affects the charging capacity of the battery in the long term. For longer periods of
inactivity, we recommend a monthly charge for at least 8 hours. When charging, no measurements should be
performed.
Operating Instructions and managing PC measuring data
The operating instructions and the measurement data management can be found on our website
http://www.draeger-msi.de/home/?L=1 under the menu item Online-Services → Download → FG4200.
The necessary USB drivers are installed automatically by downloading the PC data management.
Since 2005, EU-wide regulations apply to the disposal of electrical and electronic equipment. In
essence, these regulations set out that collection and recycling options must be available for private
households. Because the FG4200 is not registered for use in private households, it must not be
disposed of through such channels. The devices can be returned to your national retailer or to your national
Dräger Safety Organization for disposal. Please contact Dräger MSI GmbH, if you have any questions
regarding disposal.
Maintenance
To ensure proper function and accuracy, calibration and adjustment should be performed once a year. Device
maintenance must only be carried out by trained service personal.
Switching on
Press the display slightly for 1 second, then press Next.
Switching off
Select and activate the OFF menu item in the main menu or press the display for 5 seconds whilst in any
menu point.
Make sure that the gas outlet on the side is unobstructed and not closed or blocked!
Functional areas
The individual tests and measurements are accessed via the main menu.
Flue gas measurement
To perform a complete flue gas measurement, we recommend a measurement time of at least 2 minutes. In
addition to the flue gas measurement, it is also possible to calculate averages and measure the draft and
enter the combustion system date.
Switch on the device and wait for system check. Then connect the flue gas probe to the unit (see connection
diagram).
Ambient air CO measurement
Measurement of the CO concentration in ambient air. The zero point adjustment has to be done with fresh air.

Pressure measurement
Pressure measurement up to 160 mbar for gas, nozzles or kinetic pressure. Connect the measuring point of
the gas pressure hose with the pressure input P of the measuring device.
Documentation
After completion of the measurement, all measurements can be printed using the MSI IR3 infrared printer or
stored in the FG4200. An alphanumeric keyboard allows customer and system data to be entered or
changed. The saved data and measured values can be provided and printed out using PC data management
with pre-prepared measuring reports including company logo and address.
Checklists
Checklists can be configured using the PC software. Up to 4 checklists each with up to 20 items can be
stored in the device, and edited and annotated with the alphanumeric keyboard.
Data memory
Information about the data memory – e.g. number of stored customers and measurements and number of
allocated memory locations.
The stored measurements can be displayed and printed out, the inspector table can be edited.
Measurement data can be deleted.
Info
Details of the measuring device - such as type, manufacturer, software version, serial number
Settings
Customizing and setting user-specific functions - e.g. time, backlight, displaying built-in help, address input
for print-outs via the MSI IR3 infrared printer.
Additional activation of averaging, draft measurement and input of combustion system data.
Flue gas measurement procedure
1. Fuel selection
Select fuel and press Next.
2. Combustion air measurement
Insert flue gas probe into the inspection opening of the combustion air supply or optionally keep the
flue gas probe in the room air. After stabilization of the combustion air values, press Hold. Then press
Unplug flue gas probe from the gas inlet G and connect to pressure connection P. Measure draft and
arrow key >>.
3. Flue gas measurement
Insert the flue gas probe into the exhaust pipe and search for the flow centre (maximum gas
temperature, minimum oxygen concentration). After stabilization of the flow centre, press Hold or Start
for the average measurement. Then press arrow key >> twice for documentation or draft
measurement.
4. Draft measurement
press Hold. Then press arrow key >>.
5. Entering combustion system data
Enter boiler temperature and / or the smoke number and the appearance of oil derivatives. Then press
arrow key >>.
