DPI 705 Series Digital Pressure Indicator
Introduction
The Druck DPI 705 pressure indicator uses a micro-machined silicon
transducer to produce a pressure reading in units of pressure measurement.
These user instructions include the operations for all DPI 705 Pressure
Indicators, safety instructions and the requirements for intrinsically safe
instruments.

should refer to the user guide or manual.
Warnings
• Do not apply pressure greater than the maximum safe working pressure.
• Do not apply pressure greater than 1.1 bar (15.95 psi) absolute to the -ve
pressure port of differential pressure indicators.
• Remove batteries from the pressure indicator immediately when
discharged and before storage.
• Dispose of batteries in accordance with local regulations and battery
manufacturers' instructions.
• When storing and transporting batteries make sure they cannot be short
circuited.
Software Version
This manual contains operating instructions for pressure indicators with
software version 2.00 onwards. Further changes to the pressure indicator's
software may require a change to the operating instructions and an issue
number change of the manual.
