d) Then the microphone has to be placed into the calibrator. 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 General Considerations
- Wind blowing across the microphone increases the noise measurement. The
supplied foam cover
has to be used to cover the microphone when applicable.
- 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.
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).
3. Start the appropriate software.
