Dwyer Instruments DigiMag DM-1112 Installation And Operating Instructions Manual

The Series DM-1000 DigiMag
digital instrument to take the place of analog mechanical pressure gages. The
DigiMag ® Digital Gages are more versatile than analog gages with their ability to be
field-programmed to display many commonly used engineering units as well as
percent of full scale. The Series DM-1000 can be programmed in 8 commonly
used engineering units plus percent of full scale. This capability allows quick units
selection on site, eliminating the need to calculate various unit conversions. The
DigiMag Digital Differential Pressure Gages have an added feature for filter
®
applications where a set point can be input where the display will blink when the
filter is dirty, alerting the user that a maintenance action needs to occur.
Programming the Series DM-1000 is easy using the menu key to access 4
simplified menus which provide access to: Security level; engineering units; filter
set point; view peak and valley process readings; digital damping for smoothing
erratic process applications; display update to conserve battery life; zero and span
field calibration.
The Series DM-1000 DigiMag
scale accuracy of 1% on ranges down to 2˝ w.c. and 2% accuracy down to the very
low ranges of 1" to 0.25" w.c. Models are also available with bi-directional ranges.
DigiMag Digital Differential Pressure Gages offer power versatility by working with
®
9-24 VDC line power or simply 9V battery power. If using line power and
connecting the 9V battery, the battery will act as a back-up if line power is lost or
interrupted.
