Specifications - Installation and Operating Instructions
Ø5.00
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 fieldprogrammed 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 in w.c. and 2% accuracy down to the very
low ranges of 1 in to 0.25 in w.c. Models are also available with bi-directional ranges.
DigiMag® Digital Differential Pressure Gages offer power versatility by working with 9
to 24 VDC line power or simply 9 V 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.

Pressure Connections
Two integral tubing connections are provided on the back of the gage. They are sized
to fit 3/16˝ (4.8 mm) I.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. If
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.
POWER MUST BE OFF WHILE WIRING CONNECTIONS
ARE BEING MADE. DO NOT EXCEED SPECIFIED SUPPLY
VOLTAGE RATINGS. PERMANENT DAMAGE NOT COVERED BY WARRANTY
WILL RESULT.

DISPLAY MENU: diS – MENU
With the gage reading a numerical value (home position), press and hold the MENU
key until the Security MENU is displayed. Press the ▼ key until the LCD shows diS
– MENU. Press the E key to show the Display SUB MENUS.
FILTER TYPE SETTING
With the LCD reading FILt – OFF, press the E key; the display will blink. Press the ▼
key to change the filter type then press the E key to save the desired filter type.
FILt – OFF: Filter type = OFF. The filter function is disabled.
FILt – HIGH: Filter type = HIGH. 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 POINT SETTING
With the LCD reading 0.00 – SPPT, press the E key; the display will blink. Press the
▼ key to change the filter point then press the E key 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.
DAMPING SETTING
With the LCD reading 1 – DAMP, press the E key; the display will blink. Press the ▼
key to change the damping level then press the E key 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 SETTING
With the LCD reading rAtE – NORM, press the E key; the display will blink. Press
the q key to change the display update rate then press the E key to save the desired
display update rate.
rAtE – NORM: 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 ▲ key
is pressed. If the ▲ key is released, the LCD will hold and display the last pressure
reading.
NOTES:
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.If 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 ▲ key on
the front panel. Also the LCD will automatically show “ALAr” if the filter point has
been exceeded.
PEAK AND VALLEY SETTING
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 E key 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 E key while in the
VALY SUB MENU.
ADVANCED MENU: AdU – MENU
With the gage reading pressure (home position), press and hold the MENU key until
the Security MENU is displayed. Press the ▼ key until the display shows the AdU
– MENU. Press the E key to show the advanced function SUB MENUS.
Auto ZERO: auto-zero
Note: For accurate calibration, DO NOT 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 E key again to complete the auto-zero.
CAL – SPAN: full-scale calibration
With the display reading CAL – FS, apply full-scale pressure then press the E key; the
display will blink. Press the E key again to save the full-scale calibration or press the
MENU key to cancel the calibration.
