WARNING
Gauges ordered with the external power option will not come with
batteries installed. Batteries MUST NOT be installed when
operating on external power. External power option gauges are not
approved for hazardous location use.
Battery life
Battery life is about 1500 hours (60 days) of continuous use with the
backlight off. With intermittent use, batteries could last a year or more.
There is a low battery icon in the upper left of the display. It will appear
when battery level is low. Replace batteries per recommendations
found in the specifications section of this manual.
RS-232 Interface
An RS-232 interface is standard on the DPG4000. Serial
communication can be used for configuration, calibration, and to
transfer measurement data from the gauge. For detailed specifications
on the interface and software communication, see pages 14 and 15 in
this manual.
WARNING
The RS-232 interface must not be used in hazardous areas.
CLEANING
To clean the DPG4000 use a cloth with a mild cleaning solution.
Specifications
All specifications cover the temperature range from 0°C to +50°C, unless otherwise
noted.
Available Input Ranges
See page 13 for a table of available ranges in PSI plus equivalent
ranges and resolution for all engineering units
Accuracy
Positive Pressure: ±0.05% FS
Vacuum: ±0.25% FS (500 PSI gauge ranges and below)
0.1% FS for 15/30 PSI compound/vacuum versions
For gauges with full scale ranges equal to, or less than 30 psi (2 BAR),
vacuum operation is limited to -5psi (-350 mBAR). The exceptions are
the 2 compound ranges; -15 to 15 PSI and -15 to 30 PSI.
