Sound Level Meter Limit 7000.
General information
Limit 7000 is designed for measure sound level of
environment in home, in work from traffic and machinery
sound etc.
Two different weighting A or C and also Quick or Slow
response time.
A-weighting response to the human ear andfiltret. A-
weighting is commonly used for environmental cases.
C-weighting is a much flatter response and is suitable
for analysing of machinery and engines etc.
Fast is used to capture noise peaks and noise that
occur very quickly e.g hamerblow.
Slow is used for most applications. Slow response for
sound source that have a consistent noise level or to
average quickly changing levels.
Sound level can be measured instantaneous or as an
average value in a period of time, from 10 seconds to 24
hours.
Memory for 30 groups of results.
Communicate with PC by optional cabel and software
for statistics, printing or analysing.
Automatic Hold function for registration of max value.
Alarm function which show with LED light when sound
level is over selected alarm level and percent of all
measured values which are over alarm value.
Adjustable automatic off or manual off.
Built in calibration signal 94 dB.

Leq is Equivalent continuous A sound. Gives an
average noise level over an preset period of time. As
longer time period as more accurate reading. Set time of
period by push MENU- button for 8 secunds till LEQ
shows on the display. Select time period with the ▲▼-
buttons. 10sec, 1min, 5min, 10min, 15min, 30min, 1h 8h
24h. Confirm by push FUNCTION-button.
Ln funktion shows percent of all measured values which
are over or equal alarm value.
5. Push WEIGING to select A or C weighting. With A
weighting the frequency respond the human ear. A is
commonly used for environmental measuring. C
weighting is a much flatter respond and is suitable for
analysing of machines, engines etc.
A weighting will automatically be selected when
measuring Leq.
Max value.
Push MAX HOLD-button and only the peak value will be
showed on the display.
Push again for return to instantaneous reading.
Alarm.
A LED-light on the instrument shows when the value is
over selected alarm level.
Ln functionen shows percent of all measured values
which are over or equal to the alarm value. The alarm
value is preset 85 dB, but can easy be changed
between 30-130 dB.
Memory.
English

30 groups of measurings can be stored.
1. When M is showed on the display push SAVE button.
The Display show number of stored values.
2. Push READ button for reading stored values. R
shows on the display and latest value are showed. Push
▲▼- buttons for reading the other stored values.
3. Push DEL/MENU-button to delete stored value on the
display.
4. Return by push FUNCTION-button.
Calibration
Standard method for calibration requires an external
calibrator. Code no 15152-0301.
1. Push the Ө-button.
2. Select A-weighing and SLOW.
3. Place the microphone into the calibrator. Turn the
calibrator on.
4. Adjust the meters CAL potentiometer on the meters
right side with a small screwdriver so the value on the
display matches the output of the calibrator 94 dB or
114 dB.
Limit 7000 have a built in signal for calibration.
1. Push FUNCTION-button till CAL shows on the display.
2. The value on the display should be 94. If not, adjust
the meters CAL potentiometer on the meters right side
with a small screwdriver so the value on the display is
94 dB.

Ljudnivåmätare Limit 7000.
Allmänt
Limit 7000 är avsedd att mäta ljudnivån i vardagsmiljöer
t.ex. på arbetsplatsen eller trafikbuller, men också
ljudnivån från riktade objekt t.ex. maskiner.
Två olika filterkurvor A eller C samt Snabb eller
Långsam ljudupptagning.
A-filtret motsvarar det mänskliga örats
frekvenskänslighet och är lämpligt vid miljömässiga
ljudmätningar. C-filtret är linjärt och lämpar sig för
kontroll av maskiner.
Snabb (fast) ljudupptagning används då man vill mäta
hastiga ljudtoppar t.ex. ljudet från ett hammarslag. Det
långsamma läget (slow) används för de flesta
appliceringar, och ger ett stabilare mätresultat på
pulserande ljud.
Ljudet kan anges momentant eller anges som
genomsnittligt värde under en vald tidsperiod, från 10
sek till 24 timmar.
Minne för 30 mätningar alternativt kan instrumentet
anslutas till PC för registrering av mätvärden.
Automatisk holdfunktion för registrering av max värde.
Alarmfunktion som visar med LED-lampa när ljudnivån
är över ett inställt värde samt andelen mätvärden som
överstiger alarmvärdet under en mätperiod.
Inställbar automatisk eller manuell avstängning.
Inbyggd kalibreringsfunktion 94 dB.
