General safety instructions

Any use of the Dräger FG4500 requires full understanding and compliance with the operating instructions 5695100, 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 Dräger FG4500 via the USB interface with a 5 V DC / 1,5 A USB power supply adapter only.
Incomplete charging affects the charging capacity of the battery in the long term.
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 www.draeger-msi.de/ under the menu item Services→ Download → FG4500. 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 Dräger FG4500 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 On-/Off Button slightly for 1 second, then press Next.
Switching off
Select and activate the OFF menu item in the main menu or press the the On-/Off Button 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).
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 BTIR Bluetooth printer or stored in the Dräger FG4500. 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 BTIR Bluetooth 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 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
   Unplug flue gas probe from the gas inlet G and connect to pressure connection P. Measure draft and 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 >>.
