Bulletin TE-DP3

The Series DP3 Wireless Differential Pressure Manometer is a compact, highly

accurate, auto-ranging differential pressure manometer ideal for low ow applications.

The Series DP3 is used in conjunction with the Dwyer Mobile Meter

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

CHARGING BATTERY

It is required before the initial use of the manometer to fully charge

NOTICE

When the charge of the battery is almost used up, the LED on the manometer of the
wireless probe will turn solid red. There is approximately 5 minutes of battery life left at
this point. If the manometer 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
manometer.
Step 2: Plug the USB connector end of the cable into the port on the charger or PC
(LED on the charger and the manometer should both light up).
Step 3: The LED on the manometer will turn off when fully charged.
Step 4: Remove USB cable from the manometer and the charger or PC.

Lithium ion batteries are very volatile and can cause a re if
