Pulsar Model 82CA/81CA Integrating Sound Level Meters
With dB(C)-dB(A) Function
Back to 80 Series Overview
 Automatic C-A measurement mode
Ideal for HML method of hearing protection calculation
Hearing protection measurements have never been easier; The C-A mode ensures automatic measurement calculation
Expands the original concept of the basic Assessor for those with noisy work places that prefer an affordable but legal method of specifying suitable hearing protection measurements
The Models 82CA & 81CA are the ideal instruments for those who do not want to pay extra for
an instrument with 1:1 Octave Band Filters because the HML method (High, Medium and Low),
is an established and accepted method of calculating hearing protection.
All hearing protection (PPE) should be
supplied by the manufacturer with
attenuation (reduction) values for each
of the H, M and L values.
By knowing the
'C' and 'A'weighted Leq values and the
difference between them you can use
either a spreadsheet or simple formula
to prescribe suitable hearing protection
for your workforce.
C-A measurement mode
By just pressing the C-A button, the instrument will automatically switch to 'C-A'
Measurement Mode. A blue LED indicator shows that you are now measuring in 'C-A' mode
rather than the normal 'Broadband' mode.
The instrument will make an Leq measurement with dB(C) Weighting (LCeq) and will
continue until the average level has settled. When the level has settled, the instrument
will switch to dB(A) and repeat the process with 'A' weighting. When this level has also
settled, the instrument will display the LCeq, LAeq and in large digits, the resultant
LCeq-LAeq value on the screen.
Making this type of measurement has never been easier as everything is done in an
automatic cycle for you.
