The noise meter section has two independent noise meter circuits, allowing for dual measurement that can simultaneously perform measurements under different frequency weighting characteristics and time weighting characteristics with a single unit.
■ Built-in real-time frequency analysis function 1/3 or 1/1 octave frequency analysis is possible with this single unit. (Main channel) ■ Dual measurement of main and sub-channels With two noise measurement circuits, you can simultaneously measure using frequency weighting characteristics or time weighting characteristics, for example, measuring with "A weighting" while recording a signal with "C weighting." ■ Equipped with extensive data memory functions Data can be saved in manual or auto mode. One block of memory is individually allocated for manual storage and two blocks for auto storage. ■ Equipped with an infrared remote control port Remote operation is possible with an infrared remote control that has 18 functions. ■ Backup function The settings for level range and frequency weighting characteristics of the noise meter are retained even when the power is turned off, allowing you to set it back to the same settings as the last measurement simply by turning the power on. ■ Energy-efficient design for continuous 8-hour measurement Achieved double the operating time of conventional models with alkaline battery specifications. ■ Large LCD display with backlight, enabling nighttime measurements.

basic information
■ Measurement Function Dual measurement of main and sub-channels for a single input. Additionally, real-time analysis of 1/1 and 1/3 octave bands is performed on the main channel. ■ Measurement Time - Automatic: 1 to 99 (units: seconds, minutes, hours) - Manual: Measurement continues until the stop switch is pressed ■ Measurement Level Range - A-weighting: 28 to 130 dB - C-weighting: 34 to 130 dB - FLAT: 40 to 130 dB ■ Measurement Frequency Range - 20 to 8000 Hz (including microphone characteristics) - 10 to 20000 Hz (amplifier only characteristics) ■ Analysis Frequency Range - 1/1 octave: 16 to 8000 Hz - 1/3 octave: 12.5 to 12500 Hz ■ Input Level Warning Displays "OVER" when above +8 dB on the blue scale and "Under" when below -65 dB on the full scale display ■ Memory Stores instantaneous values or calculation results in manual or auto mode. Has 1 block of memory for manual storage and 2 blocks for auto storage, kept separately. ■ Display Backlit LCD display, 192 × 192 dots ■ Power Supply Four AA batteries or AC adapter
