1. Overview
Thank you for purchasing the ennoLogic eS528L sound level meter.
This meter is a precision instrument designed to measure and
display sound levels in decibel (dB) from 30 to 130 dB. Special
features include data logging, frequency weighting (A & C),
response time selection (Fast & Slow), manual and auto ranging,
data hold and MAX/MIN capture. Data logging is one the meter’s
most distinguishing features which allows you to record data to its
internal memory for later upload and review via the meter’s USB
interface.
Each unit is fully tested and calibrated at the factory. But you can
also calibrate it yourself following the instructions provided in this
manual.
The eS528L meets standards IEC61672-1: 2013 Class 2

reliable service.
