5.2 No matter, in or in state, the memorized data
can be browsed by pressing the key 3-17. The
browsing state is marked by `R` on the display.
In `R` state, all the readings memorized, can be recalled
by pressing the or key.
5.3 To delete the memorized value in memory, the
browsing state has just to be entered and the reading to be
deleted has to be located by pressing the or key.
Then the key 3-21 has to be pressed. If there appears
“Err0” on the display, this indicates that there is no more
reading to delete.
6. How to set the “Leq” Time
Leq is used to access the rms average noise level over a
preset period of time, often the staring point of a noise
assessment. To take the Leq measurement, the period of
time which has to be tested, must be selected. The longer
the period of measurement time, the more accurate the
Leq reading will be. To set the period of measurement
time, the key 3-21 just has to be pressed for about 8
seconds until “Leq” appears on the display. Then the key
has to be released and the time has to be selected among
10s, 1 min, 5 min, 10 min, 15 min, 30 min, 1 hour, 8 hours
or 24 hours by pressing the Up (3-16) or Down (3-17) key.
To quit, any key except or key can be pressed.
7. How to set the alarm value
The alarm LED is on when the instant measurement value
is bigger than or equal to the alarm value set. The default
setting value at the factory is 85dB. It can be changed to
any value between 30 and 130dB by the following steps:
The key 3-21 has to be pressed for about 5 seconds.
It has to be released after “AL” is shown on the display.
Then key or key have to be pressed to preset the
alarm value as desired.
To quit, any key except or key can be pressed.
8. How to set the time of Auto Power off
The default setting for auto power off at the factory is 5
minutes, which means that the device will auto power off 5
minutes from the time of the last key operation. This can
be changed by the user to any value between 1 to 9
minutes by the following steps:
The key 3-21 has to be pressed for about 10 seconds
and it can be released after “AUTO” is shown on the
display. Then the or key has to be pressed to
preset the time as desired. To stop the function of auto
power off, time just has to be preset to “0”. So the device
will not be powered off automatically, it can only be shut
down manually in that case.
9. Calibration
The standard method to calibrate the instrument requires
an external calibrator (ASU-01) in addition to a small
screw-driver.
9.1 Calibration of the device :
a) The device has to be turned on.
b) It has to be preset in the “A” weighting mode
c) It also has to be preset the “SLOW” response mode
d) Then the microphone has to be placed into the cali-
brator. The calibrator has to be switched ON.
e) The CAL potentiometer of the device has to be
adjusted in the way that the device’s display matches the
output of the calibrator.
9.2 Calibration of the device by the inbuilt signal
The instrument has to be switched on to enter the
calibration state. Then the key 3-18 has to be
pressed until the icon “CAL” is to be seen on the display.
The screw-driver has to be used to adjust the CAL
potentiometer of the device in the way that the device
shows 94dB.
10. Considerations
10.1 Wind blowing across the microphone increases the
noise measurement. The supplied foam cover has to be
used to cover the microphone when applicable.
10.2 The instrument may not be dismantled by
inexperienced staff. There are no parts inside which might
serve the user.
11. Battery replacement
11.1 When the battery voltage is less than approx. 5V, it is
necessary to replace batteries.
11.2 The 4 x 1.5 V batteries have to be installed correctly
into the case .
11.3 If the device is not going to be used for an extended
period, batteries have to be removed.
Note: If the AC adapter is used, batteries should be taken
out.
12. Takeover of data memory into software
Important: First start the continuous data logging and then
read out the stored data!
1. Connect the SU 130 to the PC (cable is optional
available with software ATC 01).
2. Put the SU 130 into the Memory Read Mode (by
pressing the READ-button).
