and
MI 36
Version
Pure tone: 226 Hz, 1000 Hz each with ± 1 %
Additional for MI 36: 678 Hz, 800 Hz each with 1 %
(continuous tones)
85 dB SPL ±1.5 dB SPL measured in an IEC 60318-5 acoustic
coupler according to IEC 60645-5:2004 / ANSI S3.39:1987.
The level is constant for all volumes in the measurement range.
Measured value shown in the display.
Speed at compliance peak (change in settings):
Automatic (Dynamic from 600 daPa/s for low
gradient and 200 daPa/s for a gradient larger
than 5 daPa)
Minimum (50 daPa/s): slow, very precise results
Medium (250 daPa/s): compromise of speed
and precision
Maximum (>400 daPa/s): fast, screening
0.1 ml to 8.0 ml at 226 Hz probe tone;
0.1 mmho to 15.0 mmho at 678 Hz, 800 Hz and 1000 Hz probe tone
0.0 ml to 6.0 ml (compensated)
5 % or 10 daPa, whichever is greater
5 % or 0.1 ml, whichever is greater
x-axis: Pressure in daPa
y-axis: Compliance in ml (226 Hz, 678 Hz, 800 Hz) and
mmho (1000 Hz)
Automatic, where the start and
stop pressure can be user-
programmed in the setup function.
