2.5 Battery
We recommend the use of 4 alkaline batteries (LR6/AA/AM3); observe the battery
polarity (+/-) and the marking in the battery compartment. Do not use old and new
batteries together. Remove the batteries when the instrument is not in use. The total
voltage of the 4 battery cells must not exceed 14 V, otherwise the sound level meter
will be damaged.
Practical tests show that the 4 alkaline battery cells are sufficient for an operation of
about 10 hours (depending on the battery). When using Eneloop BK-3HCCA/4BC
batteries (nominal capacity 2450 mAh), the sound pressure meter can operate for
about 12 hours in continuous operation. If the battery voltage is lower than the
minimum voltage of the sound pressure gauge, the gauge will automatically switch off.
We recommend the use of an external power supply or power supply via USB for long
operation.
Follow the diagram below when inserting or replacing the batteries:
Turn the shutter to the left to remove the battery cover. Lift off the battery cover.
Replace the batteries and close and lock the battery compartment.
