Record voltages in Table IV (last column) before contacting the factory. Be sure to use a high input
impedance digital voltmeter for the readings identified in Table IV. All readings are to be taken from
terminals BRN through R on JP2 (Figure 2) with power on and a typical flow rate flowing through the
sensor. Complete Table IV and fax it to the factory (614-895-0319).
