Specifications - Installation and Operating Instructions
Series DM-1000 DigiMag®Digital Differential Pressure Gage
The Series DM-1000 DigiMag®Digital Differential Pressure Gage is the ideal
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®Digital Differential Pressure Gage possesses a full
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. f using line power and
connecting the 9V battery, the battery will act as a back-up if line power is lost or
interrupted.

ISTALLATIO
Mounting
A vertical position required. That is the position in which all standard models are
calibrated at the factory. Provide a 4-9/16˝ diameter opening in panel. nsert gage
and secure in place with provided screws and adapters.
ncluded Accessories:
Mounting lugs –3
6-20 x 2-1/2 screws –3
4-20 x 3/8 screws – 3 (mounting hole depth is 3/8˝ [9.53])
Cable gland –1
Pressure Connections
Two integral tubing connections are provided on the back of the gage. They are
sized to fit 3/16˝ (4.8 mm) .D. x 5/16˝ (7.9 mm) O.D. flexible PVC tubing. To
measure single positive pressure, connect tubing to the + port and vent the – port
to atmosphere. To measure single negative pressure (vacuum), connect tubing to
the – port and vent the + port to atmosphere. To measure differential pressure,
connect higher pressure to the + port and lower pressure to the – port. Be sure the
pressure rating of the tubing exceeds that of the operating ranges.
Electrical Connections
A 9V battery or an external power supply 9-24 VDC can be used to power the unit.
f both battery and external power supply are connected, the battery will work as
back up power.
Battery Installation
The unit is shipped with a separate 9V alkaline battery. Remove the unit’s top back
cover, do not remove bottom cover. Connect the 9V battery to the battery holder as
shown in Figure 1. Replace top back cover and tighten screws to 2 ±.25 in. lbs.
External Power Supply Installation
Remove the unit’s back cover then connect the external power supply to the
terminal block as shown in Figure 1.

DISPLAY ME U: diS – ME U
With the gage reading a numerical value (home position), press and hold the
ME U key until the Security MENU is displayed. Press the qkey until the LCD
shows diS – ME U. Press the Ekey to show the Display SUB MENUS.
FILTER TYPE SETTI G
With the LCD reading FILt – OFF, press the Ekey; the display will blink. Press the
qkey to change the filter type then press the Ekey to save the desired filter type.
FILt – OFF: Filter type = OFF. The filter function is disabled.
FILt – HIGH: Filter type = H GH. The display blinks when pressure is greater than
the filter point.
FILt – LOW: Filter type - LOW. The display blinks when pressure is less than the
filter point.
FILTER POI T SETTI G
With the LCD reading 0.00 – SPPT, press the Ekey; the display will blink. Press
the qkey to change the filter point then press the Ekey to save the desired filter
point.
0.00 – SPPT: Filter point = 0.00. The filter point may be set to anywhere within the
range of the instrument.
DAMPI G SETTI G
With the LCD reading 1 – DAMP, press the Ekey; the display will blink. Press the
qkey to change the damping level then press the Ekey to save the desired
damping level.
1 – DAMP: Damping level = 1. The damping level can be adjusted from 1 to 15.
Damping stabilizes the display from instabilities due to things such as vibration and
excessive pressure fluctuations. The damping function adjusts the amount of
readings that are averaged for each display update.
DISPLAY UPDATE SETTI G
With the LCD reading rAtE – ORM, press the Ekey; the display will blink. Press
the qkey to change the display update rate then press the Ekey to save the
desired display update rate.
rAtE – ORM: Display update = Normal (1 second).
The gage reads the process pressure and updates the LCD every second.
rAtE – 10: Display update = 10 minutes.
The gage reads the process pressure and updates the LCD every 10 minutes.
rAtE – KEY (On-Touch mode): Display update is disabled.
The gage reads the process pressure and updates the LCD whenever the p key
is pressed. f the pkey is released, the LCD will hold and display the last pressure
reading.
OTES:
1. Depending on the Display Update setting, the battery life is shown below:
-150 hours (typical) if Display Update is set for “Normal” 1 second update. rAtE-
NORM
-9 months (typical) if Display Update is set for 10 minutes. rAtE-10
-1.5 years (typical) if Display Update is disabled. rAtE-KEY
2. f the Display Update is set for 10 minutes or disabled (On-Touch mode), the
process pressure value can be read instantly by pressing and holding the pkey
on the front panel. Also the LCD will automatically show “ALAr” if the filter point has
been exceeded.
PEAK A D VALLEY SETTI G
100.0 – PEAK: Peak value = 100.0
The peak feature stores the highest pressure reading the instrument has measured
since the last reset or power up. At power up PEAK is reset to the present pressure
reading. To manually reset the PEAK value, press the Ekey while in the PEAK
SUB MENU.
0.0 – VALY: Valley value = 0.0
The valley feature stores the lowest pressure reading the instrument has measured
since the last reset or power up. At power up VALY is reset to the present pressure
reading. To manually reset the VALY value, press the Ekey while in the VALY SUB
MENU.
ADVA CED ME U: AdU – ME U
With the gage reading pressure (home position), press and hold the ME U key
until the Security MENU is displayed. Press the qkey until the display shows the
AdU – ME U. Press the Ekey to show the advanced function SUB MENUS.
Auto ZERO: auto-zero
OTE: For accurate calibration, DO OT apply any pressure when
performing this function.
With the display reading Auto ZERO, release pressure to Zero then press the E
key; the display will blink. Press the Ekey again to complete the auto-zero.
CAL – SPA : full-scale calibration
With the display reading CAL – FS, apply full-scale pressure then press the Ekey;
the display will blink. Press the Ekey again to save the full-scale calibration or
press the ME U key to cancel the calibration.
MAI TE A CE
This model is not field-serviceable and should be returned if repair is needed (field
repair should not be attempted and may void warranty). Be sure to include a brief
description of the problem plus any relevant application notes. Contact customer
