Manual

Introduction

Congratulations on your purchase of the Triplett SL600 Digital Sound Level
Meter.This meter measures and displays sound pressure levels in dB (decibels) from 30 to 130dB in three measurement ranges. In addition to the LCD numerical displays, a bargraph is included for quick and easy viewing of sound level changes. Features include selectable Frequency Weighting (‘A’ and ‘C’), selectable Response Time (Fast and Slow), Max/Min Hold, and
AC/DC analog outputs. PC cable and software enable the user to download and analyze measured data. This meter is shipped fully tested and calibrated and, with proper use, will provide years of reliable service.

Unique flat surface, modern housing design
Automatic Data Hold
“MAX/MIN/AVG/DIFF” function
Emissivity Digitally adjustable from 0.10 to 1.0
Adjustable High and Low Alarms

BASIC OPERATION

Turn the meter ON by pressing the
Select ‘A’ or ‘C” frequency weighting by pressing the A/C
Select Fast or Slow response time by pressing the FAST/SLOW
Use the LEVEL button to select the appropriate range. The range is shown near the top of the display. Use a range that puts the sound level reading in the center of the If the OVER or UNDER icons appear on the display, select a new range if possible.
The numeric and bargraph displays indicate the sound level
To turn the meter off, press and hold the button for 3

LEVEL

The LEVEL button is used to select the measurement range. Press this button to step through the ranges as indicated on the display (30 to 80, 50 to 100, 80 to 130, or 30 to 130 autoranging)

A/C FREQUENCY WEIGHTING

Press the A/C button to select ‘A’ or ‘C’ frequency weighting. With ‘A’ weighting selected, the frequency response of the meter is similar to the response of the human ear. ‘A’ weighting is commonly used for environmental or hearing conservation programs such as OSHA regulatory testing and noise ordinance law enforcement. ‘C’ weighting is a much flatter response and is suitable for the sound level analysis of machines, engines, etc. Most noise measurements are performed using ‘A’ Weighting and SLOW Response.

FAST/SLOW RESPONSE TIME

Use the FAST/SLOW button to select a FAST (125 ms) or a SLOW (1 second) response time. Select FAST to capture noise peaks and noises that occur very quickly. Select the SLOW response to monitor a sound source that has a consistent noise level or to average quickly changing levels. Select SLOW response for most applications.

HOLD

Press the HOLD button “freeze” the current reading in the display. Press the button again to resume normal operation.

MAX / MIN

In the MAX/MIN mode the meter will display and hold either the maximum or minimum reading. The display will update only when the measured value exceeds the value presently in the display.

Press the MAX/MIN button and the MAX icon will appear on the The reading displayed is the highest reading encountered since the MAX mode was entered.
Press the MAX/MIN button again. The MIN icon will appear on the display. The reading displayed is the lowest reading encountered since the MIN mode was
Press the MAX/MIN button again to exit the MAX / MIN display

RECORDING DATA

The meter can store up to 20,000 readings at an interval rate of 1 to 59 seconds. Each recording session is saved as a data set and each record is saved with a date and time stamp. This data can be downloaded using the supplied software.

Setting the interval time

Press and hold the button while turning the meter 0001 and Int will appear in the display.
Press the LEVEL button to set the sample interval from once per second to once per 59
Press the HOLD button to save the interval setting and exit the setting

Recording readings

Press the REC button to begin recording. The REC icon will appear on the display.
Press the REC button again to stop
Auto Power OFF is disabled when the record function is active.

Clearing Stored readings

Turn the meter OFF.
Press and hold the REC button while turning the meter
When (clear) appears on the display, release the REC
All of the readings that were stored in memory are now

BACKLIGHT

Press the button to turn the LCD backlight on or off. To conserve battery life, the backlight will automatically turn off after approximately 30 seconds.

AUTO POWER OFF

The meter will automatically shut off after approxi m ately 15 minutes of inactivity. Press the SETUP

button to disable the auto-power-off feature. The icon in the display indicates that the auto power off feature is active.

ANALOG OUTPUTS

The meter is equipped with an analog output feature. The analog output jack is located on the meter’s side panel and requires a 3.5mm stereo phono plug. (1- AC Output, 2-DC Output, 3- Ground)

AC analog output

The AC output is a retransmitted representation of the meter’s measurement (note that the output factors in the meter’s frequency weighting selection ‘A’ or ‘C’).
Output voltage: 1Vrms at full scale of the selected range. Output impedance: 100Ω approx.

DC analog output

The DC output signal reflects the frequency weighting selected (‘A’ or ‘C’). Output voltage: 10mV (±1mV) per displayed dB. Output impedance: 1KΩ approx.

Calibration

Frequent calibration is recommended and is often required by noise standards and directives.

Turn the meter ON
Put the meter in the ‘A’ weighting mode
Put the meter in the ‘SLOW’ response mode
Place the calibrator onto the microphone.
Turn the calibrator ON.
Adjust the meter’s CAL potentiometer located on the side panel so that the meter’s display matches the output of the calibrator (typically 94dB or 114dB).

Battery Replacement

The battery icon will appear on the display when the battery needs replacing.
Turn the meter OFF and slide the rear battery cover off.
Install the 9V battery and replace the cover.
Never dispose of used batteries or rechargeable batteries in household waste.
As consumers, users are legally required to take used batteries to appropriate collection sites, the retail store where the batteries were purchased, or wherever batteries are sold.
