Pressure/ Vacuum Transducer Module
Introduction
The PV350 Pressure/Vacuum Transducer Module (the module)
measures gauge pressure; the difference between atmospheric
(barometric) pressure and the pressure (or vacuum) applied to the
pressure port on the transducer. It then converts that measurement to
1 mV dc per unit. A module and a high-performance digital multimeter
(DMM) with min/max function become a datalogger capable of measuring
peak high and peak low.

Page 1: Safety Information
Be sure that pressure is removed before • disconnecting any hoses or tubing from the PV350 transducer. Follow accepted safety procedures for systems on • which pressure or vacuum measurements are made. Make sure the PV350 is serviced by a qualified • technician. - Page 2 PV350 and any hoses or fittings. Plug the PV350 into the DMM (red polarity dot to volts input) and set the multimeter to mV dc. Check the battery voltage (see Testing the Battery).

Page 3: Testing The Battery
When measuring vacuum the DMM displays a minus sign. • Testing the Battery Turn the DMM and the module OFF and connect the PV350 to the DMM. Turn the DMM on and set the DMM to the mV dc range. -
