Maximum peak voltage 

20 V  Peak-Peak  (Maximum  peak  voltage  of  input  sinusoidal 
signal,  which  can  be  lead  to  the  SLM  without  destruction  the 
meter) 

 

Warm-up time

 

1 min. (for 0.1 dB accuracy) 

Nominal delay

  

less than 3 seconds

 

(between operating of the "Reset- Button" 

and beginning of a new measurement)

 

Typical stabilization time

 after change in 

environmental conditions by 20

C

 

1 hour 

Nominal  delay 

between  operating  of  the 

"Reset-  Button"  and  beginning  of  a  new 
measurement

 

< 3 sec 

Time  shift  after  completion 

of  a 

measurement,  before  a  measurement  is 
shown

 

< 1 sec 

 

Note: When  the  instruments  are  moved  from  a  warm  environment  with  high  humidity,  
to  a  colder  environment,  care  should  be  taken  not  to  produce  condensation  inside  
the instruments. In this case, much longer stabilization periods may be necessary. 

Environmental, electrostatic 

and radio frequency

 

criteria 

 

Effect of humidity

 

< 0.5 dB (for 30%<RH<90% at 40

C and 1000 Hz) 

Effect of magnetic field

 

< 15 dB (A) or < 25 dB (Z) (for 80 A/m and 50 Hz) 

Effect of radio frequency fields

 

< +/-0.5 dB @ 74 dB and 10V/m

 

electromagnetic field

 

The greatest susceptibility (the least immunity) is achieved when in the SLM the 

Z

 filter and time weighting 

F

 

are selected, and the SPL measurements are considered. 

The  greatest  susceptibility  is  achieved  when  the  SLM  is  placed  parallel  to  the  radio  frequency  field.  
In addition, if there is an extension cable, the greatest susceptibility is achieved when the SLM and cable is 
placed along field and the cable is coil as solenoid.  

Effect of electrostatic discharge

 

meets requirements of IEC 61672-1:2013

 

During electrostatic discharge, the influence of the displayed results could be observed.  

No changes in instrument operation state, configuration or stored data corruption were found out. 

 

Effect of ambient pressure

 

< 0.01 dB/kPa

 

 

Effect of temperature

 

< 0.5 dB (from -10

C to + 50

C) 

Operating range 

from -10

C to + 50

C 

Storage

  

from -20

C to + 60

C 

 

Effect of Vibration

 

 

 

1. 

For mechanical vibrations with an acceleration of 1 m/s² vertically to the membrane of the microphone for 
the frequencies 31,5 Hz, 63 Hz, 125 Hz, 250 Hz, 500 Hz, 630 Hz, 800 Hz and 1000 Hz increases the low 
level of the linear operation range to 70dB for the frequency weighting “A”.

   

2. 

For mechanical vibrations with an acceleration of 1 m/s² parallel to the membrane of the microphone for 
the frequencies 31,5 Hz, 63 Hz, 125 Hz, 250 Hz, 500 Hz, 630 Hz, 800 Hz and 1000 Hz increases the low 
level of the linear operation range to 65dB for the frequency weighting "A".
