Type Approval Option
NTi Audio #: 600 000 377
The Type Approval Option upgrades the instrument to the
XL2-TA, the sound level meter dedicated to certified mea-
surements. The XL2-TA with the M2230 microphone forms
a type approved sound level meter offering class 1 per-
formance in accordance with IEC61672, IEC61260 and
ANSI S1.4.
The Type Approval Option includes
XL2-TA Firmware V4.21 (approved Firmware)•
Sticker XL2-TA•
XL2-TA Manual (available online at www.nti-audio.com/XL2)•
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 pop-•
up 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.
XL2 Vibration Option
NTi Audio #: 600 000 436
The Vibration Option turns the XL2 Analyzer into a professional
vibration meter with broadband measurements and spectral
analysis in 1/3 or octave resolution. The XL2 Vibration Meter
determines vibration acceleration, velocity and deflection with
standard-compliant weighting filters in the frequency range
from 0.8 Hz to 2.5 kHz. Detailed recording of measurement
data and audio files allow for comprehensive evaluation and
reporting. In addition, the XL2 Vibration Meter comes standard
with an FFT analysis and an oscilloscope function. Selectable
FFT frequency ranges from 1 Hz to 1.69 kHz allow a detailed
examination of the measured vibrations.
The Spectral Limits Option adds functions to the Vibration Me-
ter including a zoom FFT up to 20 kHz and a 1/12 octave band
analysis from 0.73 Hz to 1.36 kHz. Also, it adds the ability to
record reference spectra and set tolerances for pass / fail qual-
ity control measurements. The Remote Measurement Option
allows the real-time acquisition of measurement data directly
into a computer application via the USB interface. A document-
ed command set is available.
The Vibration Option is supported by the XL2 with firmware
V4.11 or higher.
