2. Making a Measurement
1. Press the utton to switch the meter ON.
2. Press the utton to select the desired frequency weighting.
3. Press the utton to select the desired response time.
4. The ma indicator shows the maximum sound level encountered during a measurement
period; the min indicator shows the minimum sound level. Press the utton to reset min
and max value.
Switching-off the instrument
In order to switch the equipment off, press and hold the utton for approx. 3 seconds.
Note that switching off the equipment is only possi le from the main screen.
The measuring instrument can switch off automatically after 6 min.
If the attery conditions are so low that in fact it could lead to errors during the
measurement, the equipment will automatically switch off, which is signaled earlier y the
attery empty indicator.
3. Calibration
Cali rating the Sound Level Meter (SL-100) requires an acoustical cali rator which provides a
sta le sound pressure at 1kHz and 94dB.
Press and hold the utton for 5 seconds to cali rate the meter.
Using the utton, you can switch etween one of the two types of cali ration:
1. Factory – Select this option if you want to use the meter's factory cali ration set during
manufacture.
2. User – Select this option if you want to use your own cali ration.
If you decide to select option "User," you will e a le to choose etween a new cali ration (NEW –
press utton ) and the cali ration of the user stored in the device's memory (CURRENT – press
utton ).
Option "NEW" allows you to perform a new cali ration as follows:
1. Stand away from loud sound sources that may interfere with the cali rator's signal.
2. Fit Sound Level Cali rator carefully onto the sound level meter and rest the assem ly on the ta le
or other flat surface.
3. Switch on the cali rator and wait approximately 5 seconds for all levels to sta ilize.
4. Press the utton to START the cali ration.
5. Wait until the display shows the value in the range of 93.8 - 94.0 dB.
6. To confirm and save the cali ration, press the utton.

4. Maintenance and Service
SL100 is designed and constructed to provide many years of relia le operation. However, if a fault
occurs that impairs the meter's correct function, then remove the atteries to prevent risk of further
damage.
For more information a out preventing faults or damage to your sound level meter, please read the
Instrument Care section elow.
Warranty
Notwithstanding the statutory warranty claims, NOVANEX provides a warranty in accordance with
the laws of the Customer's country for a period of at least two years from the date of sale of the
device to the end user. The warranty covers only those faults which are caused y defects in

The warranty does not cover devices that are partially or entirely disassem led.
Instrument Care
Protect the instrument from impact. Do not drop it or su ject it to rough handling. Transport
it in the supplied carrying case.
Never mix fresh and partially-used atteries.
Do not attempt to remove the mesh cover from the microphone as this will cause damage
and affect the accuracy of the instrument.
Protect the instrument from water, dust, extreme temperatures, high humidity and direct
sunlight during storage and use.
For long-term storage, remove the atteries. Do not leave exhausted atteries in the
instrument, as they may leak and cause damage.
If the instrument casing ecomes dirty, then wipe it with a lightly dampened cloth. Do not
use a rasive cleansers and solvents. Do not allow moisture to enter the microphone,
connectors or casing.
Power supply
The SL100 is powered y two AA atteries. You may use either disposa le or rechargea le
atteries. The attery status is indicated y the attery charge level. If an empty attery icon
is displayed, replace the atteries. Batteries should e replaced with a new set of atteries of
the same kind. Do not use a rechargea le attery in com ination with a disposa le attery or
a partially discharged attery with a full attery.
