Series DP3 Wireless Differential Pressure Module
Specications - Installation and Operating Instructions
Bulletin TE-DP3
The Series DP3 Wireless Differential Pressure Module is a compact, highly
accurate, auto-ranging differential pressure module ideal for low ow applications. The
Series DP3 is used in conjunction with the Dwyer Mobile Meter®application software
to view pressure drop across lters, static pressure in ducts, and velocity pressures
from pitot tubes or air ow stations.
The Series DP3 includes a differential pressure sensor with positive and negative
ports for differential and static pressure readings, a LED indicator, and a rechargeable
lithium-ion battery; which can be charged via Mini-USB. The Series DP3 Utilizes
Bluetooth®Low Energy (BLE) to communicate wirelessly in real-time with the Dwyer
Mobile Meter® application software.
FEATURES/BENEFITS
• Auto-ranging technology maintains optimal performance down to 0.1˝ H20
• LED indicator displays module status, connection, charging and logging to the user
• Over-the-air updates ensure the module has the latest rmware
• Unit can be mounted on both the pitot and velocity grid
• Rechargeable battery allows for a 10 hour battery life
• One button design allows for easy operation and simple logging
• Rugged case allows for a 10´ drop without compromising functionality
• Automatically corrects pressure reading depending on the inclination of the module
APPLICATIONS
• Non-corrosive dry gases
• Building commissioning
• Building HVAC test and balance
• Industrial process verication
• Instrumentation validation

CHARGING BATTERY
When the charge of the battery is almost used up, the LED on the module of the
wireless probe will turn solid red. There is approximately 5 minutes of battery life left
at this point. If the module is not already paired to the base unit, it will not pair while in
low battery condition.
Step 1: Plug the mini-USB connector end of the cable into the bottom of the module.
Step 2: Plug the USB connector end of the cable into the port on the charger or PC
(LED on the charger and the module should both light up).
Step 3: The LED on the module will turn off when fully charged.
Step 4: Remove USB cable from the module and the charger or PC.
NOTICE
If desired, the DP3 can be operated with USB powered cables less
than 3 m in length when connected to the charger or PC.
It is required before the initial use of the module to fully charge the
battery for 12 hours.
NOTICE
NOTICE
Lithium ion batteries are very volatile and can cause a re if
punctured or severely damaged. Only use a Dwyer Instruments,
Inc. approved charging device in a well ventilated area away from any ammable
materials or gases. Do not incinerate the battery. Only charge between 32 to 113°F
(0 to 45°C).

CONNECTING THE DP3
For the latest instructions, please refer to the “Help” button in the Options menu in the
Mobile Meter® app.
1. Verify that the UHH4 or newer universal handheld device, or a smart device with
the Dwyer Mobile Meter®app has Bluetooth® technology turned on. Open the
Mobile Meter® app by clicking on the icon.
2. Press “Without Bridge”.
3. The next screen will display a message that reads “Searching For Probes”. When
the DP3 is turned on and discovered by Mobile Meter®the
name of the probe will appear on the screen. Click the checkbox next to the desired
probe.
4. Use the back button or navigation arrow to go back to the Probes List page.
MAINTENANCE/REPAIR
Upon nal installation of the Series DP3, no routine maintenance is required. The
Series DP3 is not eld serviceable and is not possible to repair the unit. Field repair
should not be attempted and may void warranty.
