If the microphone is ever dropped (the effects of this can be minimized by PCB’s rugged grid cap or utilizing 
rugged microphone kits), or comes into contact with any contamination, or is exposed to extreme tempera-
tures, immediate recalibration of the microphone should be performed. When using a rugged grid cap, a 
handheld calibrator with a 1” diameter (example CAL250,  or pistonphone) is required for recalibration, 
along with the larger (079A59) calibration adapter.  Please note that heat from your hands can affect the 
calibration results. It is always good practice to wait a minimum of 30 seconds after placing the microphone 
on a test system before taking a calibration reading in order to minimize the effect that heat from your hands 
has  on  the  calibration.  Changes  in  the  environmental  conditions:  temperature,  humidity  or  atmospheric 
pressure, may cause a change in your microphones sensitivity and thus, changes in your output accuracy. It 
is always recommended to calibrate both before and after your test, within the test environment. Performing 
a single point handheld calibrator check, both before and after your test, ensures reliability of the test data. 
With proper maintenance, the microphone and preamplifier should provide stable and accurate results for 
years to come.

Calibration 

PCB offers recalibration services for our precision microphones, as well as units produced by other A2LA 
manufacturers.  Our  internal  metrology  laboratory  is  certified  to  ISO  9001,  accredited  by  A2LA  to 
ANSI/IEC 17025 and ANSI/NCSL Z540-1, complies with ISO 10012-1 (and former MIL-STD-45662A), 
and uses equipment directly traceable to one or more of the following National Labs (NIST, PTB or DFM). 
Our investment in equipment, traceability and conformance to industry standards ensures accurate calibra-
tion against relevant specifications. We also carry a line of acoustic calibrators that can be used to calibrate 
microphone sensitivity on site as needed. 

Hand calibration of sensitivity for most prepolarized microphones may be performed with a Larson Davis 
CAL250  or  CAL200  (or  equivalent).    The  CAL250  produces  114  dB  SPL  at  251.2  Hz.    The  CAL  200 
produces either 94 dB or 114 dB (user selectable) at 1000 Hz.  Note that both the CAL250 and CAL 200 
are compliant with ANSI S1.40-2006, Specifications and Verification Procedures for Sound Calibrators, 
Class1 and IEC 60942-2003, Class 1, Sound Calibrators.
