Windscreen (WS012)
Wind blowing across the microphone generates pressure fluctuations
on the microphone diaphragm. This can contribute to an inaccurate
measurement. To achieve the best result, we recommended using the
WS012 windscreen provided with this model. The Larson Davis WS012
windscreen is a 1” diameter cone made of open cell foam, which
contributes to the most accurate measurement.

G4 LD Utility (G4) software enhances the features, flexibility, and
ease-of-use of Larson Davis instruments. Use it to set up, calibrate,
and remotely operate the Spartan dosimeter. Additionally, you can
use G4 to download, chart, and analyze measurement data files, print
and share a custom report, and export data to third-party software for
post-processing and analysis.
2.1.1 Installing G4 from the Web
This process also works well if you want to update a currently installed
version of G4.

2.6 Installing the Dosimeter On the Wearer
Calibrating your Spartan 730 helps you determine the true sensitivity of
your dosimeter–including all effects from the microphone,
preamplifier, and dosimeter. It also establishes a numeric relationship
between the sound pressure level at the diaphragm of the microphone
and the voltage of the meter. Once this relationship is established, the
meter accurately displays the sound pressure level.
The Spartan 730 is equipped with an auto-calibration feature to
simplify this process. As shown in section 2.5 Calibrating Your Spartan
Dosimeter, when the calibration levels are measured, the 730
dosimeter displays the resulting levels and gives you the opportunity to
accept the calibration, or to reject and begin the process again.
FIGURE: Accepting Calibration Details
LCeq is the dB level measured with the
calibrator tone applied.
Delta is the difference between that
measured level and the calibrator’s
output level.
730 Dosimeter Reference Manual Rev B Calibrating Your Spartan Dosimeter 23
Overload Condition
During calibration, your meter determines the overload level (dB Peak)
for A, C and Z frequency weightings.
Simply stated, the overload level is the sound pressure level in dB that
would overload the instrument. This can occur when a signal from the
preamplifier exceeds the calibrated input range of the dosimeter.
When this condition exists, the Spartan 730 displays an Overload
indicator on the LCD display, in the LD Atlas app, and in the G4 LD
Utility.
FIGURE: Spartan 730 Overload Indicator in the LCD Display
Overload indicator
Calibration Stability
The Spartan 730 maintains a stable value of sensitivity over long
periods of time. As part of the meter’s auto-calibration, the result is
documented as the Calibration History.
TAKE NOTE Your copy of the
calibration certificate is on the
included Larson Davis USB drive.
After the auto-calibration, the dosimeter makes an automatic
comparison of the meter’s current sensitivity value and the value from
the previous calibration. If the difference is greater than 3 dB, the meter
displays a Large Change Notification as shown below.
FIGURE: Spartan Dosimeter Large Change Notification
This screen notifies you that the dosimeter’s current
sensitivity is different from the previously measured
sensitivity.
Changes like this may indicate that it’s time for your
dosimeter to be serviced.
We recommend that you maintain your dosimeter’s calibration history.
Significant changes in sensitivity, or a pattern of small but regular
sensitivity changes, indicate that your dosimeter should be serviced.
Your dosimeter has been calibrated and certified to exact
specifications. We recommend that you re-certify the calibration
annually. We can also schedule the recertification service based on
your requirements.
To contact Larson Davis, see Contact Larson Davis.
2.5.2 Larson Davis Calibrator & Accessories

1/4-inch adapter
(ADP109)
About the Adapter (ADP109)
The CAL150 and CAL200 calibrators require a
1/4-inch adapter (ADP109). If your dosimeter
package included a calibrator, the 1/4-inch
adapter was attached. If needed, additional
adapters are available from Larson Davis
Technical Support.
To install the adapter, firmly insert the narrow
edge into the slot on the bottom of the
calibrator. The adapter’s part number should
be visible around the circumference.
About Post-Calibration Data
We recommend that you post-calibrate directly after the measurement
and prior to downloading the data files. This creates a postmeasurement entry in the Calibration History.
After you post-calibrate, connect to G4. When downloading data files,
your Spartan dosimeter appends the most recent post-calibration
values to each file as it downloads.
If you post-calibrate after the data files download, connect your
dosimeter once again to G4 or the Atlas app. Both utilities will attempt
to add post-calibration values to a data file when you open it.
If you format and restore to factory defaults, all calibration history is
deleted except for the single, most recent post-calibration values. This
entry becomes the initial entry of a new Calibration History record.

noise measurement, see 4.2 Best
Practices for Measuring Noise
Exposure.
Clip the dosimeter to clothing on the worker’s shoulder, with the
microphone nearest to the ear. It may be effective to consider the
worker’s position in relation to the loudest sounds in the environment,
and to secure the dosimeter on the shoulder most exposed to the noise
source.
