15.3 Malfunctions, causes and possible solutions
❖ Calibration procedure fails:
The calibration correction is applied and written in the Curr.Att. field, along with the date and time, only
if it is within the expected range. If the calibration procedure fails, the correction is not applied and
written.
Failure to apply the correction may be due to the following factors:
•
microphone out of nominal specification
•
sound calibrator out of nominal specification
•
acoustic calibrator off or with incorrect level setting
•
expected calibration value (expected field) not set correctly with respect to the calibrator used.
Possible solutions:
•
Ensure that the instrument is not exposed to high noise and/or vibration and that the acoustic cali-
brator and sound level meter are firmly aligned, and the microphone is fully inserted into the cali-
brator cavity.
•
Check that the rubber sealing ring inside the calibrator cavity is not damaged and is correctly posi-
tioned.
•
Repeat after waiting for the end of the stabilization time.
❖ The sound levels measured by the sound level meter appear to be incorrect:
•
Check that the preamplifier is fully inserted into the connector on the sound level meter (the
push-pull connector "clicks" when correctly inserted).
•
Ensure that the microphone capsule is correctly screwed onto the microphone preamplifier.
•
Verify that there is no dirt on the microphone protection grid.
•
When using a microphone extension cable, try connecting the preamplifier directly to the sound
level meter, excluding the cable as a possible cause of malfunctioning.
•
Check that the displayed acoustic parameter is correct (we recommend using an instantaneous
parameter such as LAFp)
•
Check that the microphone protection grid is screwed tightly onto the capsule.
•
Ensure that there is no condensation on the microphone capsule or preamplifier. Avoid switching
on the sound level meter in conditions where condensation may occur. For measurements in high
humidity or rain, use the WSO outdoor microphone protection unit.
•
Activate the preamplifier heater.
❖ The sound level meter switches off immediately after the power-up presentation screen:
•
Battery is depleted and must be charged, use external power supply as an alternative.
❖ The sound level meter does not communicate with the PC:
•
Check that the connection cable is correctly plugged into the USB-C connector on the sound level
meter and that it is connected to a USB socket on the PC.
•
If the USB interface is used, check that, on the sound level meter, are not activated functions for
which the USB port is to be disabled (e.g. Log_Sync or measurement with storage).
❖ Continuous logging cannot be activated. The instrument starts measurements without data record-
ing:
•
Out of memory. Download data and/or delete memory.
❖ Manual audio recording does not work:
•
Check that the audio logging mode is on TRG (EDIT APP > LOG > AUDIO > Audio logging = TRG).
