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

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
easure single positive pressure, connect tubing to the + port and vent the – port
m
o atmosphere. To measure single negative pressure (vacuum), connect tubing to
t
he – port and vent the + port to atmosphere. To measure differential pressure,
t
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.
CAUTION
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.

The gage reads the process pressure and updates the LCD whenever the p key
is pressed. If the p 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-
