4. FUNCTIONAL CHARACTERISTICS DESCRIPTION
• This sound level meter complies with IEC651 Type 2 and ANSI S1.4 Type 2.
• With the measuring scope from 30 to 130 dB and automatic shifting function
• A and C weighting network selection
• High speed (FAST)/Low speed (SLOW) response rate selection
• Maximum (MAX) locking function
• Digital display, good anti-interference performance, power saving
• With the backlight feature, it is appropriate for gathering the sound data at
night. To save power, backlight auto power off function is provided.
• Composite material injection molding process is adopted for casing with
anti-drop structure design. It is not only extremely wearresisting, but also
elegant.
• With power saving and high-reliability circuit design, well-designed high-
efficiency power supply circuit makes the batteries more durable.
