The XL2-TA Sound Level Meter received the type approval for the hardware configurations “D2” and “E0”. These instruments can be upgraded with the TA-Option, thus resulting in a type approved sound level meter. Any XL2 Analyzer with another hardware index can be returned to NTi Audio for upgrading the hardware configuration.
All M2210 and M2215 measurement microphones with serial numbers 1499 or higher may be upgraded to a M2230 measurement microphone by assembling the MC230 capsule.
Please contact NTi Audio for more details.
