INTRODUCTION

The Sper Scientific Advanced Datalogging Sound Meter
(Model 850013) uses a single range of 30 ~ 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 folowing indicator to determine the battery
capacity.

When the battery power is almost empty, the 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 18.

SETUP MODE

Setting the Clock

This meter includes a clock that records the date and time

along with measured data.

1. Press and hold CLOCK for longer than 2 seconds.

2. Press or
adjust the next item.

3. The setting adjustment order is year→ month→ day→

hour→ minute→ second. Press CLOCK to complete
adjustment. To cancel a setup process, press POWER.

Note…

An internal (rechargeable) backup battery runs the clock

when the meter is turned off. The backup battery is

recharged by the main batteries. The clock will run for 30
minutes on the backup battery alone. If the meter will not
be in use for an extended period (one month or longer),
remove the main batteries to prevent possible damage due
to battery fluid leakage. After reinstalling the batteries, set
the date and time.

to adjust the number, press CLOCK to

CALIBRATION

The meter has been factory calibrated. Annual calibration
is recommended for best results. Calibrate the instrument
before use if the meter was not used for one month or
longer or was operated in an undesirable environment (high
temperature and/or humidity, heavy dust).

1. Prepare for calibration by setting up the meter as
follows:

 Frequency scale: A
 Time weighting: FAST
 Measurement mode: Disable Min/Max function.
 Level range: 30 ~ 130 dB

2. Insert the microphone housing carefully into the insertion
hole of the acoustical calibrator.

3. Switch the calibrator to emit 94.0 dB. Turn the calibrator
on. Using the calibration tool, adjust the CAL
potentiometer on the meter until the LCD displays 94.0
dB.

MEASUREMENT PROCEDURES

1. Press POWER to turn the meter on.

2. Select the desired response time and frequency
weighting.

Note…

If the sound source consists of short bursts or sudden
changes in sound level, set the response time to FAST. To
measure typical sound level, use the SLOW setting.

3. Hold the meter in a comfortable position or attach to a
tripod and point the microphone towards the noise
source. The sound pressure level reading will appear
on the LCD.

Maximum and Minimum

1. With the meter turned on, press MIN/MAX. “MAX” and

the maximum value appear on the LCD. The LCD will
continuously update and display as new maximum
values are reached.

2. Press MIN/MAX again. “MIN” and the minimum value

appear on the LCD. The LCD will continuously update
and display as new minimum values are reached.

3. Press MIN/MAX again. The maximum and minimum

indicators will blink simultaneously to indicate that the
meter is recording maximum and minimum values. The
current value displays on the LCD. To view the
maximum and minimum values obtained during
recording (since Step 1 in the Maximum/Minimum

instructions), press MIN/MAX to view the maximum and
press MIN/MAX again to view the minimum.

15

MEASUREMENT PROCEDURES

4. To exit this mode and clear all maximum and minimum

values, press and hold MIN/MAX until “MAX MIN”

disappears from the display.

Note…

Maximum and minimum values cannot be saved when
exiting the Maximum/Minimum Mode or when the meter is

turned off.

Datalogging

The data storage method can be set to auto or manual.

Auto Datalogging

To set the interval time:

1. Press INTV. “Int” and a seconds display appear on the

LCD.

2. Set the recording interval in minutes and seconds by
pressing or to adjust the number. The
maximum setting is 1 minute. The minimum setting is 1
second (“00:01”).

3. Press INTV to save and return to Normal Mode or press
POWER to cancel.

4. Press REC to start recording the measurements. The
values are stored in the meter’s memory. Press REC

again to stop recording.

Note…

While the meter is recording, most of the meter’s buttons

(such as RECALL, MEM, INTV, A/C, FAST/SLOW) will not

function. Setting adjustments should be made before
recording. When the maximum of 31,000 records are

display on the LCD. If there are no data in a data set,

“MEM00” appears on the LCD. Press RECALL to exit

Recall Mode.

Clearing Manually-Stored Data

Press and hold RECALL. While still holding RECALL,
press and release POWER. “CLr” appears on the LCD.

The LCD displays “SURE 5, 4, 3, 2, 1, 0.” (The meter allows

5 seconds to abort the operation by releasing RECALL.)
Continue holding RECALL until the meter returns to Normal

Mode. The memory is now cleared.

17

BATTERY REPLACEMENT

1. Remove the screw at the top of the battery cover and lift
the cover off the meter.

2. Insert 4 AA batteries, ensuring correct polarity.

3. Replace the battery cover and tighten the screw to
secure.

Note…

This meter can use AA rechargeable batteries. A separate
charger must be provided for rechargeable batteries
because the meter is not designed to recharge batteries.

18

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 affect 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 Specifications (page

30) 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 qualified personnel only. Please
contact Sper Scientific to speak with a technician.

 Periodically wipe the meter with a dry cloth. Do NOT

use abrasives or solvents on this meter.
