TABLE OF CONTENTS

INTRODUCTION

The Sper Scientic Advanced Datalogging Sound Meter (Model 850013)

uses a single range of 30 to 130 dB. This dynamic range eliminates the

need to manually select and change ranges, alleviating the problem of

lost data associated with range changes in auto-ranging models. All test

parameters are simultaneously displayed on a large, bright backlit display

that features 0.1 dB resolution and a bar graph. Data can be stored in the

meter or directly saved on a computer through the PC interface.

This meter measures sound in decibels (dB). Although it is used for a wide

variety of other measurements in science and engineering, the decibel is

most commonly recognized as a measure of the intensity of a sound wave.

The decibel is a unit of power ratio with the number of units equal to a

constant times the logarithm to the base 10 of two sources of intensity.

POWER SUPPLY

The meter is powered by 4 AA 1.5V batteries or an AC adapter. When

using the AC adapter, insert the adapter plug into the DC9V connector

on the bottom of the meter.

Note…

When the AC adapter is connected, the meter will supply power from

the adapter rather than the batteries.

When using batteries as the power source, periodically check the battery

indicator on the top left of the screen to determine the battery capacity.

When the battery power is almost empty, the empty battery symbol will

disappear from the LCD. Press MEM or REC. “Lo Bat” appears on the

LCD. If the meter is in recording mode, it will stop recording.

For battery replacement, see page XX.

MAINTENANCE

The following actions will keep the meter in good working condition and

ensure correct measurement technique:

• Wind blowing across the microphone may cause additional noise and

a󰀨ect the reading. When taking measurements in a windy environment,

the windscreen must be used to prevent interference.

• Do not store or operate the meter in high temperature or high humidity

environments. See Specications (page 14) for recommended

operating environment ranges.

• Keep the microphone dry and avoid severe vibration.

• Remove the batteries and store the meter in a low humidity

environment when not in use for an extended period of time.

• Repairs or services not covered in this manual should be performed

by qualied personnel only. Please contact Sper Scientic to speak

PC CONNECTION

System Requirements

Windows NT 4.0/ NT2000/ XP/ VISTA

Minimum Hardware Requirements

PC or Notebook with Pentium 90 MHz or higher, 32 MB RAM; At least

50 MB hard disk space available to install the software. Recommended

resolution of 800 x 600.

Installing the Software

Note…

Di󰀨erent computer systems may require slightly di󰀨erent installation steps

than those below.

1. The rst most important step in software installation is to verify that

the target system meets the general hardware requirements of the

application. Beginning the installation in a computer machine which

does not possess the minimum requirements can lead to either an

unsuccessful installation or failure of the program to run after installing it.

2. Since programs in general are written to be Operating System

dependent, make sure that the version of the application you are installing

corresponds to the Operating System platform running on your machine.

3. Aside from the general hardware requirements, some computer programs

also have software requirements prior to installation. Double check if you

need to update or upgrade your Operating System or if there is a need to

download other tools or utilities.

4. Once all the initial requirements have been met, make sure that there

are no unnecessary programs running before beginning the installation

procedure. In some instances, applications may require that the antivirus

programs be disabled. Make sure that you are installing a legitimate

application before disabling your protection software.

5. Software installation can be done either from the Internet (skip to step

8) or from an installation disc provided by the software manufacturer.

To install from the disc, simply open the CD or DVD drive and insert

the installer.

6. A setup wizard window should be launched. In case there is none, open

the Explorer and navigate to the optical drive. Double click on either the

Autorun or Setup le.
