Pressure/ Vacuum Transducer Module
Instruction Sheet
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.

Safety Information
Warning
To avoid eye injury, always wear approved safety glasses
when working with this instrument.
To avoid injury from pressure explosion:
•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.

PV350 English Instruction Sheet
Page 2
•To ensure that the module is used safely, follow all
safety and operating instructions in this Instruction
Sheet. If the module is not used as described in this
Instruction Sheet, the safety features of the module
might be impaired.
•Do not use the module if the module or fittings look
damaged, or if you suspect that the module is not
operating properly.
• This symbol on the module indicates that an
operator should refer to an explanation in the
instruction sheet.
•Follow accepted safety procedures for the systems on
which pressure or vacuum measurements are being
made.
Materials Compatibility
The PV350 is compatible with industrial gases and liquids that are
compatible with 316 stainless steel. To determine the compatibility of a
liquid or gas, refer to the manufacturer's specifications. When making
measurements on more than one type of pressure system, make sure the
fluids or gases in those systems are compatible. If they are not,
contamination or damage to the system being measured may result.
Cleaning
Clean the module using a soft cloth and mild soap and water. Do not
immerse the PV350 in liquids.
Clean the transducer and connectors after each use with a cleaner
appropriate for the liquid or gas connected during measurement. Refer to
the manufacturer’s instructions for the proper cleaning material.
Measuring Pressure and Vacuum
Caution
The sensor diaphragm can be damaged by solid or sharp
objects. Never insert any object into the inlet port.
Clean the sensor immediately after use with appropriate
solvents (refer to the solvent manufacturer's instructions).
Note
Fluke recommends that Teflon sealing tape (or its equivalent)
be used in fitting threads to ensure good seals between the
PV350 and any hoses or fittings.
1. Plug the PV350 into the DMM (red polarity dot to volts input) and set
the multimeter to mV dc.
2. Check the battery voltage (see Testing the Battery).
3. Press the English/Metric button to select the desired units.
4. Slide the switch to the desired setting.
5. Before applying pressure, zero the module by turning the ZERO
potentiometer until the DMM displays zero. (Zero on the range you
will be using and rezero the DMM whenever the scale is changed.)

Figure 1. Operation
Note
The Relative or Zero function on your DMM (if available) can
be used instead of the ZERO potentiometer to zero the meter.
Refer to the multimeter's user manual for instructions on using
this function. Zeroing the meter does not affect the module's
specified accuracy.
6. Apply pressure/vacuum to the PV350 and read the DMM display.
•When measuring pressure, if the DMM displays OL,
switch the multimeter range from millivolts to dc volts.
Increasing the range to dc volts moves the decimal
position three places to the left (500 psi displays as
0.500 V).
•When measuring vacuum the DMM displays a minus sign.
Testing the Battery
1. Turn the DMM and the module OFF and connect the PV350 to the
DMM.
2. Turn the DMM on and set the DMM to the mV dc range.
3. If the DMM displays less than 100 mV, replace the battery.
How to Replace the Battery
Warning
To avoid electrical shock, disconnect the module from all
devices before opening the case. Be sure to completely
reassemble the module before attempting to use it.

Battery
Figure 2. Battery Replacement
1. Turn the module OFF and unplug it from the DMM.
2. Remove the screw from the back of the module, separate the case,
and replace the battery.
3. To reassemble, line up the holes in the case with the
METRIC/ENGLISH switch and zero knob. Then snap the two halves
together. Reinstall the screw.

Conversion Factors
psi = inches of H2O x (3.6127 x 10-2) inches of H2O = psi x 27.68
psi = mm of H2O x (1.4223 x 10-3) mm of H2O = psi x 703.1
psi = cm of H2O x (14.223 x 10-3) cm of H2O = psi x 70.3
psi = bar x (14.503) bar = psi x 0.0689
psi = lbs/ft2 x (6.9444 x 10-3) lbs/ft2 = psi x 144
psi = mbar x (1.4503 x 10-2) mbar = psi x (68.9513)
psi = Pascals x (1.4503 x 10-4) Pascals = psi x (6.895 x 103)
All H2O conversion factors are @ 4°C
