The Type Approval Option upgrades the instrument to the XL2-TA, the sound level meter dedicated to certified measurements. The XL2-TA with the M2230 microphone forms a type approved sound level meter offering class 1 performance in accordance with IEC61672, IEC61260 and ANSI S1.4.

The Type Approval Option includes

• XL2-TA Firmware V4.71 (approved Firmware)
• Sticker XL2-TA

How do I get my XL2-TA ready for accreditation?

• Install the Type Approval Option on the XL2 and apply the XL2-TA sticker on top of the XL2 label on the display.
• Download the dedicated firmware for accreditation to your XL2 from the XL2 Support Page at https://my.nti-audio.com.
• After the firmware installation, the XL2-TA starts with a popup window “XL2 Type Approved SLM/RTA“. The sound level meter function SLM/RTA may be accredited now.

The type approved firmware deactivates the X-Curve in the SLM function and the unit SPL in the RMS/THD+N function.
