Goto the input selection menu ( Setup – Input) and
select Sound Channel 1 (or 2 if applicable).
The Select Sensor menu contains several choices of
sensors. The available Outdoor Microphones is listed
separately. Select the Nor1216 if available. If not see
below how to add the Nor1216 to the available sensor
list.
In the Sound channel menu you select horizontal or
vertical correction.
The horizontal correction gives you the option to switch
on correction for a larger windscreen that can be added,
the Nor4576.
Select outdoor microphone type to Nor1216.
Serial Number;
Key in serial number of the 1216
In the outdoor frame, select microphone capsule type
and serial number. Legal selections are; Nor1225,
Nor1227 or Nor1228. The two latter are prepolarised.
The system automatically selects polarization voltage
according to the selected microphone.
It is possible but not mandatory, to key in an under scale
spectrum to give warning if the measured levels are
influenced by the microphone’s self-noise spectrum.
Once you have selected capsule type, a list of preamp-
lifier data have to be entered.
Enter Serial number and Gain. Gain is the attenuation in
the preamplifier. You may leave this to 0 and adjust the
overall sensitivity by an acoustical calibrator to correct
reading. However, it is recommended to use a value
to have a better match between the verified sensitivity
given in the microphone capsule calibration certificate
and the real calibration you perform with an acoustical
calibrator. A typical value is -0,3dB
In the Verification frame you enter name of the calibra-
tion laboratory of the microphone capsule, date of
verification, microphone sensitivity and the time interval
between each verification. When the verification date
is due, the instrument will display a warning at start up.
Hint! The Select Sensor menu is a
dynamic menu. You may add a new
sensor if needed.
