Instruction Manual
Connecting the
Nor1217 to
Sound Analyser Nor140
The Nor1217 is designed to be used with the Sound
Analyser Nor140. The Nor140 supports all the needed
corrections, system check facilities for the two types
of microphones. This chapter discuss how you set up
and use the Nor140.
In the SETUP – 1 (Instrument menu) – 4 (Input menu),
you select which type transducer you have connected.
Select either “1214/16/17 Vertical” for Nor1217 with
vertical frequency correction applied and “1214/16/17
Horizontal” for Nor1217 with horizontal frequency cor-
rection applied. If the Nor1227 is used as microphone
cartridge, the polarization voltage should be set to OFF.
Set it to ON if Nor1225 is used
It is not needed to do any settings in the “2:corrections”
in this menu. This is all pre-set when selecting the 1217
as transducer.
The point 1: “Level range” should not be used, unless
high levels above 140dB need to be measured. This
requires the use of the Nor1225 which is a 200V polar-
ised microphone cartridge. This will not work with the
Nor1227. Please also consult the instruction manual for
the Nor140 for further information about the use of the
“high level” setting.
