Product overview

A/C characteristics

*1 Approximately 30 minutes (cancellable)

It supports both a "digital display" that allows you to instantly check the measurement value, and an "analog display" that allows you to instantly recognize the change in the measurement value on a graph.

Compliant with international standard IEC 61672-1.
The maximum or minimum measurement value can be displayed.
Equipped with an alert function that displays "OVER" when the measurement value exceeds the set analog range, and "UNDER" when it falls below.
The time constant can be switched (FAST/SLOW) depending on the measurement target.
Calibration function included (A-weighted only. Calibrator sold separately.)
Comes with AC/DC output terminal.

Supports A/C characteristics and FAST/SLOW switching.

It supports both "A-weighting," which is close to human hearing and is used for general noise measurement, and "C-weighting," which is suitable for measuring sound pressure levels with a high level of low frequency components such as impact sounds. It is also possible to switch between "FAST" weighting (time constant: 125 ms), which provides measurements close to the response time of the human ear, and "SLOW" weighting (time constant: 1 s), which provides measurements of the average level of fluctuating noise.

Supports two types of display: "analog display" and "digital display."

It supports two types of display: an "analog display" that allows you to instantly recognize the amount of change, and a "digital display" that allows you to instantly check the measurement value.
