1. Test equipment for the humimeter BMC
1.1 Verification process
To do so: The device and the test equipment must have a temperature between
20.0 °C and 26.0 °C.
1. Check whether the measuring chamber of the device is empty.
»When switching on, there must be no measuring material or contamination in
it.
2. Switch on the measuring device and press the key for 3 seconds.
3. Now the query for self-calibration (adjustment)
of the device appears. Confirm this with the key
(Figure 1).
»This process is completed in a few seconds.
4. The measuring chamber must now be filled
completely with the test medium (white plastic
granules) slowly and evenly (Figure 2).
»Fill the measuring chamber from the gray rear side.
»Do not use a funnel or similar for filling the measu-
ring device!
5. Spread the granules evenly on the top edge
(Figure 3).
»No material may be compressed in the process!
6. Now the characteristic curve "Reference" must be
selected with the arrow keys.
7. Readings between 11.0 and 13.0 indicate that
the meter is correctly adjusted.
»If the measured values are below 11.0 or above 13.0, then contact Schaller
Messtechnik GmbH or your dealer!
8. Pour the test medium back into the bucket.
»Make sure that no residues collect in the measuring chamber.

2. Test equipment for the humimeter BMA-2
2.1 Verification process
To do so: The device and the test equipment must have a temperature between
20.0 °C and 26.0 °C.
1. Check whether the measuring chamber of the
device is empty.
2. Place the empty measuring chamber correctly in
the BMA-2 (Figure 4).
»The aluminum part must be centered in the plastic
jaws of the drawer.
3. Now close the drawer and push it downwards
(Figure 5).
»Usually happens automatically!
4. The round plug of the supplied power supply unit
on the BMA must be connected (Figure 6).
5. Now connect the power supply unit to an earthed
socket.
6. Now the humimeter BMA-2 switches on automa-
tically.
»IIf this is not the case, press the key for 3
seconds.
7. After switching on, the device performs a charging
test. The display shows Check Door (Figure7).
8. Now comes the query for self-calibration (Adjust) of
the humimeter BMA.
(Adjust?). Confirm this with the key
(Figure 8).
9. After successful self-calibration, the measurement
window is visible on the display
(Figure 9).

10. Now open the drawer of the humimeter BMA and remove the measuring
chamber.
»This must first be raised, then it can be opened.
11. The measuring chamber must now be filled
completely with the test medium (white plastic
granules) slowly and evenly
(Figure 10).
»Fill the measuring chamber from the side with the aluminum sheet.
12. Spread the granules evenly on the top edge.
13. Hang the filled measuring chamber correctly back into the drawer and close it.
14. Now the characteristic curve "Reference" must be selected with the two arrow
keys.
15. After pressing the Start button, the measurement starts automatically.
»The LED now flashes blue and three symbols for the active measurement appear
on the display.
16. After the measurement is completed, the LED lights up blue again and the meas-
ured values are shown on the display.
17. Readings between 10.5 and 12.5 indicate that the meter is correctly adjusted
(Figure 11).
»If the measured values are below 10.5 or above
12.5, then contact Schaller Messtechnik GmbH or
your dealer!
18. Open the drawer and carefully remove the measur-
ing chamber.
19. Pour the test medium back into the bucket.
»Make sure that no residues collect in the measuring chamber.
ATTENTION
The test equipment must always be stored in a closed bucket to prevent mois-
ture absorption.

3. Checking the calibration of the humimeter FSG
The calibration of the device should be checked every four weeks. Use the optionally
available test equipment (Art.No. 11758) for checking.
3.1 Checking the scale
1. Switch on the scale.
2. Place the test weight on the scale (Figure 12).
3. The scale should now display a reading of 500 g
(Figure 13).
»If the balance indicates a measured value with a
deviation of more than 0.5 g, the balance can be
readjusted (see the balance operating manual).
3.2 Checking the device
To do so: The device and the test equipment must have a temperature between
17.0 °C and 23.0 °C.
1. Check whether the measuring chamber of the
device is empty.
»Empty the device and clean the measuring chamber
if necessary.
2. Switch on the device.
3. Now the query for self-calibration (adjustment)
of the device appears. Confirm this with the key
(Figure 14).
4. Select the "Reference" characteristic curve using
the arrow keys (Figure 15).
5. Place the empty clean measuring cup (0.5 liter)
on the switched off balance and switch it on.
»The balance must indicate 0.0 g with an empty
measuring cup, the measuring cup must not be
weighed as well.
6. Fill the measuring cup with 900 g of the granu-
les (Figure 16).
