3.4 Operating Mode
The Flow and Pressure Meter PC 410 is a high precision mul­timeter for the measurement of differential pressure, volume flow and temperature as well as the registration of humidity and ambient pressure. (These two functions are only available in the version AF). Because of its extremely high precision, the meter measures even very small pressures. Therefore, it is ideal to determinate air speed, gas pressure, volume, tension and also the flue gas temperature. A maximum measuring range up to 100 hPa and a burst pressure of 0.75 bar provide a sufficient degree of security even for high pressure ranges.
3.5 Display and key setup
1. The PC 410 has a color 2.4' display.
2. The OLED-technology allows reading the display from
almost any angle of view.
3. Four keys are available below the display to operate the

• Press "menu" to activate the main menu. In the main menu,
all submenus and applications can be activated. The fol­lowing submenus can be selected:
Fig. 17: Main menu
Page 21

6.2 Option “Air flow (k value)” Select the submenu "Air flow (k-value)" to measure the air flow at apertures or similar measuring openings of air pipes or vents. This method is simple and precise and therefore suitable for the adjustment of air pipe systems and vents.
6.2.1 Theoretical background In this menu, the air flow measurement is based on the k value. The k value is a factor which describes the relation between the decrease in pressure and the air flow.
The air flow of measuring equipments mentioned in chapter
6.2 is proportional to the term
r
Dr
.
The different manufacturers indicate the proportionality factor in a different way (see table 1). In the PC 410 the measure­ment type is indicated with the corresponding short descrip­tion (see table 1). The user can choose the unit of the volume flow in the setup-menu (l/s, m³/h, m³/s, cfm). The factory setting is l/s and m3/h respectively.
NOTE!
If you select a certain measurement type in the setup-menu, the displayed unit will not change automatically.
The PC 410 will always calculate with the unit l/s, even when another unit is displayed. Table 1 shows the formula used for the calculation.
For all calculations, the PC 410 will consider the standard air density r, if no external temperature probe is connected. When a temperature probe is connected, the air density will be calculated automatically.

6.2.2 Connecting the meter to the vent
• Connect the Wöhler meter with two measuring hoses to the
vent.
The overpressure socket (+) of the meter has to be connected to the aperture with the higher pressure and the underpres­sure socket (-) to the aperture with the lower pressure.
NOTE!
If the hoses are wrongly connected, the reading will be negative. In this case inverse the hoses.
• During the measurement, the Wöhler meter can be fixed to
the protective grid with a magnet, so that the results can easily be read from the display.
• When the aperture is under the ceiling, the meter can be
fixed with the hand strap.

6.5 Option “Air speed” In the air speed mode, the air speed (v) of the gas is meas- ured in m/s when the gas temperature is 800 °C or less.
Fig. 34: Connection of the S-tube probe to the PC 410
NOTE!
An S-tube probe (see accessories) is needed for this meas­urement.
The wanted signal of the Wöhler S-tube probe is better than that of a normal pitot tube, if the air speed is equal. In the setup-menu the pitot factor 0,93 must be set once (see chapter 6.12).
6.5.1 Measuring the air speed
1. Connect the pressure connector of the S-tube to the (+)
overpressure socket of the Lindab PC 410.
2. Connect the static pressure connector of the S-tube to
the (-) underpressure socket of the Lindab PC 410.
3. In calm air, switch on the Lindab PC 410 and wait until
the zeroing procedure of the sensor has finished.
4. When closed, the S-tube can be inserted through the
measurement opening into the gas flow.
5. Fix the S-tube with a cone, open it and direct the sensors
as shown in the figure.
6. If necessary, adapt the S-tube to the cross section of the
gas line with the help of the two knurled screws.
NOTE!
The S-tube must be adjusted before the measurement pro­cedure starts, since it is required to check and/or adjust the oppositely running orientation of the measuring tubes after loosening the knurled screws and adjusting the immersion depth.

6.6 Option “4 PA Test” The 4 Pa Pressure Test is a simple control of the underpres- sure limit 4 Pa for the confirmation of a sufficient combustion air supply.
In a closed room or in connected rooms, simultaneous opera­tion of non-roomsealed heating appliances and ventilation and air conditioning systems can cause dangerous under pressure.
With the 4 Pa Pressure Test the underpressure value can be controlled. The readings are plotted in a graph during about 4 minutes, and can be saved and print out afterwards.
Fig. 37: PC 410 with capillary hoses
NOTE!
For the 4 Pa Test two capillary hoses must be connected to the PC 410.
The 4-Pa Test measures the pressure difference between the room where the fireplace is installed and another room which is not connected (e.g. outside air, stairway etc.). Before starting the measurement, two flexible capillary hoses must be connected (see accessories). The pressure sensor of the meter will measure the pressure difference.
Before starting the measurement:
1. Select 4 Pa Test in the main menu of the PC 410. The
current differential pressure reading will be displayed.
2. Connect the capillary hose leading to the reference point
(stairway or outside air) to the negative pressure socket (Fig. 1, part 10).
3. Connect the second capillary hose to the positive pres-
sure socket (Fig. 1, part 9). The second hose stays in the room where the fireplace is installed. With this hose the march of pressure will be recorded.
Underpressure in the fireplace room in relation to the pressure at the reference point will lead to a negative differential pres­sure.

How to perform the 4 Pa Pressure Test:
4. Switch on appliance and all air conditioning (fan, dryer)
with maximum power.
5. Open an outside window or a door to the reference room
and test proper operation of the appliance, ensure that there are no backdraft conditions.
6. Position the reference capillary hose: Lead the hose out-
side through a window seal or into the stairways through the door rebate or the keyhole.
Fig. 39: 4-Pa Test
NOTE!
Especially on stormy days, the stairways may be a stable reference room.
If the stairways are used as reference room, all windows, doors, cellar doors and trap doors have to be closed.
The second capillary hose will stay uncut in the fireplace room.
7. Press „PD =0“ to zero the pressure sensor.
8. Press "Start" to start the 4-PA Test.
The meter will now record the pressure profile for 4 minutes.
9. Open the window/door for about 30 seconds, so that the
zero line can be registered.
10. Close the window/door for about 30 seconds, control
underpressure.
11. Open the window/door for about 30 seconds, the zero
line should be reached again.
12. Close the window/door for about 30 seconds, control
underpressure.
13. Open the window/door for about 30 seconds, the zero
line should be reached again.
14. Close the window/door for about 30 seconds, control
underpressure.
For a better orientation, every 30 seconds there are auxil­iary lines in the diagram. After a maximum of 4 minutes, the measurement will stop automatically.
Fig. 40: Pressure profile during the 4 Pa Test
NOTE!
Press "Stop" to stop the 4 PA Test earlier.
Page 36
36
Normally a diagram as shown in Fig. 41. will appear. The pressure peaks in the diagram are caused by the rapid move­ment of the window or the door and therefore they are not relevant for the interpretation of the diagram.
In Fig. 41 the pressure drop is about 2,0 Pa.
The reliability of the system is considered suffi-cient, when the pressure drop caused by opening and closing the window is less or equal to 4 Pa (8 Pa in the case of wood burning without surrounding air).
After the 4 Pa test is completed, "4 Pa Test" will be marked by a tick mark in the main menu. Se-lect "Print" from the main menu to print out the readings and select "Save measure­ments" (see chapter 0) to save them.
For the detailed procedure according to the Technical Rules for Gas Installations (TRGI), working sheet G 625 (2009), it is necessary to replace the fireplace by the Wöhler DP 23 (see manual Wöhler DP 23).

Measuring the Ventilation Loss The ventilation loss has to be measured 30 seconds after
burn-out. It is based on the measurement of the flow speed and of the temperature of the residual core flow. The test fulfills the requirements of DIN EN 15378, national annex, concerning the evaluation of the ventilation loss of boilers.
How to perform the measurement:
Fig. 46: S-tube probe
NOTE!
A room temperature probe can be connected. Connect the Special Wall Temperature Probe (see accessories) to jack 12, fig. 1.
If you do not connect any room temperature probe, the tem­perature measured by the internal probe will be adopted.
• In the submenu "Heating check", select "ventilation loss".
Confirm with OK.
• Enter or control the parameters. (Nominal power, diameter
of the flue gas pipe, outside temperature and ambient pres­sure).
Press "Procced". A message will appear: "Zeroing pressure sensor. Remove hoses."
• Confirm with "OK". The pressure sensor will be zeroed. It is
important that the S-tube probe is not connected yet.
NOTE!
If the Lindab PC 410 is equipped with an internal ambient pressure probe, the meter will determine the ambient pres­sure automatically.
• Connect the S-tube probe to the Lindab PC 410.
• Insert the closed S-tube through the measurement opening
into the gas line, while the burner is working.
• Fix the S-tube with a cone, open it as shown in Fig. 47 and
direct the sensors as shown in the figure.
• If necessary, adjust the S-tube with the knurled screws, so
that it fits into the gas line.
NOTE!

6.8 Option „Volume“ In this submenu, the content of a closed hermetic room is determined (e.g. tank, bottle or pipe) with a volume up to 6000 l.
NOTE!
For the volume measurement, a a medical sy-ringe (up to 100 ml), a Wöhler Soot Test Pump, a cross-union and connection hoses are needed. We recommend the Wöhler Leakeage Test Set.
Measuring principle of the determination of the volume
After a sample V
sample
has been drawn with the syringe (up to 100 ml) or the soot test pump, the pressure in the tube will change. Based on this pressure change, the total volume V
tube
can be determined.
The Volume V
tube
is determined with the following equation in
accordance with the principle of the Boyle-Mariott's Law:
V
Tube

ambient pressure, has to be entered in the setup menu by the user (Default: 1013 hPa)
The Lindab PC 410 measures the pressure difference ∆p. For an exact measuring result, the pressure difference ∆p should at least amount to 200 Pa so that an exact result can be reached. Therefore, the sample V
sample
that the user draws with the syringe or the soot test pump should amount to at least 1/500 of the tube volume (see table).
Guidelines for the selection of the sample volume that has to be drawn with the soot test pump.
Pump volume Max. tube volume
163 ml (1 strike with the soot test pump)

Performing the test
Fig. 53: Volume measurement with the Lindab PC 410 and a syringe (up to 100 ml tube volume).
NOTE!
If the volume is smaller or equal 100 ml, a sy-ringe has to be used. If the volume exceeds 100 ml, a Soot Test Pump will be needed. The vo-lume of the Soot Test Pump is 163 ml per strike.
• Close the gas line and seal it with a suitable test plug.
• Switch the Lindab PC 410 on before connect-ing the over-
pressure socket (+) via a hose to the test plug.
• Connect the soot test pump or the syringe with a second
hose and the cross piece.
• Go to the main menu, select "Volume" and confirm with
OK.
• Enter the test volume into the meter according to the
