, sound power, and FpI. The range of available func- tions depends on the selected measurement standard. The Nor150 will, in combination with the Nor1290 probe and the Nor1294 phase veriﬁ cation coupler, ensure that most intensity measurements may be performed with a single 12 mm spacer.
Page 105: Setting Up The Instrument For Intensity
Instruction Manual Setting up the instrument for intensity The Nor150 may utilize a wide range of probes, both pre-polarized and 200 V polarized microphones in different conﬁgurations. However, the highest perfor- mance and ease of use is achieved using the Nor1290 probe kit.
Page 106 To use the probe handle, connect the probe at the top of the rod, then add an extension cable between the bottom end of the rod and the Nor150. The optional smartphone will provide the same view as the Nor150 itself, offering a one-hand operation of intensity meas- urements.
