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
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).
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.)
