When the measurement is paused, the measurement state icon will show whether the back
erase is available or not:
: Back erase is invalid.
: Back erase is valid, then press <ESC/Back Erase> key and all integral data will be
restored to the state before 5 seconds.
4.3.2 MEAS.Range
Menu of MEAS.Range display the Linearity Range, Dynamic
Range and Peak C Range.
The new developed algorithm brings a single measurement
range that no needs to change the range anymore. The
algorithm can meet the requirement of toneburst response
down to 0.25ms with only 0.1dB error at 4kHz. And the error is
0.4dB for 0.125ms toneburst test at 4kHz.
Linearity Range: The measurement result can be considered to be correct only when the
result located in the linearity range. Otherwise, the error of measurement result is over the
acceptance limits. Sometimes linearity range also can be called measurement range.
Dynamic Range: Dynamic range is the range between the self-generated noise level and
the maximum input signal level. Dynamic range is the maximum range which can be display
on the sound level meter. Note the measurement result near the self-generated noise level
can be considered is non-linear.
Peak C Range: Peak C range is the linearity range of Peak C measurement. The Peak C
measurement result located in this range can be considered to be correct.
4.3.3 ICCP Power
Menu of ICCP power control the 4mA/24V constant current
source which can supply all kind of ICCP sensor. Please
disable ICCP power before connect to other kind of sensor or
directly connect to signal source. Press <◄>, <►> can choose
and select.
