Sound Examiner SE-400 Series
80
Cable and radio frequency emission (sections: 5.18.1, 5.18.2, 9.3n)
The charging cable is a shielded 1 meter long USB cable.
Battery voltage range and power supply (sections: 5.20.2, 5.20.3, 9.3j)
The charging circuit stops charging when the battery voltage reaches its maximum of 4.1 Volts DC. The unit shuts down
when the minimum battery voltage of 3.4 volts DC is reached. The instrument may be operated with a USB power cable.
Electrostatic discharges (section 6.5.2, 9.2.7 b)
Exposure to electrostatic discharges will not change operating state, change of configuration or corruption or loss of stored
data.
AC power and radio frequency (sections: 6.6.1, 6.6.3, 6.6.4, 9.2.7c, 9.3o)
No effect was observed in any orientation or configuration of the SE-400 SERIES within a 60 Hz 80 A/m magnetic
field. During radio frequency immunity testing, a 3-meter USB cable was connected between the SE-400 Series and
a computer USB port. The SE-400 Series was set to display SPL.

Sound level meter type (sections: 5.1.4, 5.1.7, 7.3, 9.2.1 a, and 9.2.5b)
Class 1 when using the BK4936 microphone. Class 2 when using the QE7052 microphone. Group X. Model SE-400
Series. This is applicable with all accessory configurations. The configuration for normal mode of operation with
the SE-400 Series is operating the instrument without the remote cable and windscreen. To conform to the
specifications for directional response and frequency weightings, the instrument is mounted in a free-field facility
using strings.
General Information (section 9.3)
The reference sound pressure level is 114 dB. The one range is the reference range. The microphone reference point is the
center of the microphone face.
