Dwyer HM35 - Manual (Page 4)

1 Description
The HM35 digital pressure gauge is a pressure-measuring instrument with an integrated
pressure sensor for the measurement of differential, relative or absolute pressures and
vacuum. Its versatile range of functions and high precision render it suitable for a wide
range of applications. Via the infrared interface (IR) and SCPI (Standard Commands for
P
rogrammable Instruments) commands, the HM35 can communicate with a PC. Its
operation is very simple, and supports the user in his measurement tasks.

2 Safety information
•
The pressure values and overload levels
stated on the rating plate and quoted in
these operating instructions must not be exceeded, as otherwise the pressure
sensor could be destroyed
or there could be a risk of injury.
• Only use pressure hoses with a maximum loading capacity corresponding to that
necessary for the application.
• Ensure that the pneumatic hoses are securely fitted! Do not use damaged or kinked
hoses.
• Do not open up the instrument (this would void the guarantee).
• The instrument must be stored within the permissible storage temperature range.
The instrument must not be put into operation in an
explosive environment!
Wear eye protection if working with pressures > 1bar !
