INTRODUCTION
This Sper Scientic Integrating Sound Datalogger measures the sound
pressure levels (SPL) according to the specied weighting and integrates
the weighted SPL over an established length of time, such as an 8-hour
workday, in order to measure accumulative sound exposure (Leq). Test
parameters are simultaneously displayed on a large, bright, backlit
display, featuring 0.1 dB resolution and a bar graph. Up to 64,000 data
records can be stored in the meter and saved, graphed, and processed
on a computer through the USB interface and included software. The
meter complies with IEC 61672:2013 Class 2 and ANSI S1.4:2014 Type
2 meter standards.

The meter automatically turns o after 30 minutes of inactivity. To
disable this function:
1. Press POWER for 3 seconds to turn the meter o.
2. Press and hold SET.
3. Press POWER while continuing to hold SET until the meter is
functioning and the automatic shuto indicator has disappeared
from the LCD.
Note…
Automatic shuto is disabled during recording or when the meter is
connected to a computer. The automatic shuto icon
is located in the
upper left.
Recording Interval Setup
Note…
When pressing ▲ or ▼ to adjust a value, you can scroll more quickly by
holding down the button.
1. Press SET.
2. Press REC/INTV. “Int” displays and the seconds will ash.
3. Press ▲or ▼ to increase or decrease the recording interval from a
minimum of one second up to a maximum interval of one minute.
4. Press REC/INTV to save the selection and return to Normal Mode,
or press POWER to cancel and return to Normal Mode.
Integrating Measurement Time Setup
1. Press INTEG TIME. The time increment ashes.
2. Press ▲or ▼ to select 10 seconds; 1 Minute, 5, 10, 20, or 30
minutes; or 1, 2, 4, 8, 16, or 24 hours.
3. Press INTEG TIME to save the setting, or press POWER to cancel.

Leq
Sper Scientic’s Integrating Sound Datalogger measures sound pressure
level (SPL) according to A or C weighting and integrates the weighted
SPL over an established length of time, such as an 8 hour workday, to
calculate cumulative sound exposure (Leq).
Press SPL/Leq to toggle between SPL and Leq. For Leq measurement:
1. Press ►װ■ (Start/Pause/Stop) to begin measurement. ► displays
along with the elapsed measurement time.
2. During measurement ►װ■may be pressed to pause or restart
measurement. ► will display if measurement is paused.
3. To cancel the measurement, press ►װ■ for 2 seconds.
4. “OVER” or “UNDER” will display if the measurement is out of range.
5. Measurement will stop and ■displays when the Leq measurement
time is up.
Note…
SET, FAST/SLOW, and A/C are disabled during Leq measurement.
Date and Time Setup
The clock should be set before rst use and after reinstalling the batteries.
1. Press SET.
2.
Press CLOCK to enter Date and Time Setup Mode. The date and time
will display in YY-MM-DD and HH-MM-SS format and the year will ash.
3. Press ▲or ▼ to adjust the year.
4. Press CLOCK to select the month.
5. Press ▲or ▼ to adjust the month.
6. Press CLOCK to select the day.
7. Press ▲or ▼ to adjust the day.
8. Press CLOCK to select the hour.
9. Press ▲or ▼ to adjust the hour.
10. Press CLOCK to select the minutes.
11. Press ▲or ▼ to adjust the minutes.
12. Press CLOCK to select the seconds.

Note…
An internal backup battery will continue to power the clock for 30 hours in
the absence of both the AA batteries and a DC adapter. The backup battery
will recharge when AA batteries or a DC adapter powers the meter.
CALIBRATION
The meter has been factory calibrated. Annual calibration is
recommended for best results.
1. Press POWER for 3 seconds to turn o.
2. Press and hold MIN/MAX and then press
POWER to turn the meter on. “CAL
94dB” displays.
3. Fully insert the microphone into an
acoustic calibrator with a ½ inch
insertion socket such as Sper
Scientic’s 850016.
4. Set the calibrator to emit 94.0 dB and
turn the calibrator on.
5. Press ▲or ▼ to increase or decrease
the reading to 94.0 dB.
6. Press MIN/MAX to save.
7. Press POWER to exit calibration.

MEASUREMENT PROCEDURES
Note…
Wind blowing across the microphone may cause additional noise and
aect the reading. When taking measurements in a windy environment,
the windscreen must be used to prevent interference.
A-Weighting: Per the IEC 61672:2003, it is weighting applied to account
for relative loudness perceived by the human ear.
C-Weighting: Mandated to Class I sound level.
1. Press POWER to turn the meter on.
2. Press FAST/SLOW to toggle between fast and slow response time.
a. Select “FAST” response time to measure sound peaks or short
bursts of sound across 125 miliseconds.
b. Select “SLOW” response time to measure average sound levels
across 1 second.
3. Press A/C to toggle between A- and C-weighting.
a. Select A-weighting.
b. Select C-weighting.
4. Hold the instrument in your hand or x it on a tripod and point the
microphone at the source of the sound.
5. The sound pressure level displays.
Backlight
1. Press BACKLIGHT to illuminate the LCD screen.
2. The backlight will shut o automatically after 30 seconds, or press
BACKLIGHT to turn it o sooner.
Minimum/Maximum Mode
1. Press MIN/MAX to enter Minimum/Maximum Mode and record
minimum and maximum values. “MAX” displays along with the
maximum value.
2. Press MIN/MAX. “MIN” displays along with the minimum value.
3. Press MIN/MAX. “MIN MAX” blinks to indicate that the meter
is recording minimum and maximum values. The current value
displays on the LCD.
4. Press and hold MIN/MAX for 2 seconds to exit Minimum/Maximum
Mode and clear the readings.

Recording Data
Note…
Most of the buttons on the meter are disabled during recording. All
settings must be selected before recording begins.
1. Press REC to begin recording the readings. If 64,000 readings have
been stored, “FULL” displays on the LCD.
2. Press REC to stop recording.
Note…
the meter will not record if battery power is extremely low.
Clearing Stored Data
