The Series WDPM Wireless Differential Pressure Module transmits measurements
to Models UHH and UHH2 or the Dwyer Mobile Meter

across lters, static pressure in ducts, and velocity pressures from pitot tubes or air ow
stations. When using it with a pitot tube or air ow measuring station, the measurement
can be calculated to read directly in air velocity or volumetric air ow. The module
mounts in the holder on the back of the handheld, or in an optional mounting bracket.

Wireless modules can take measurements from at least 50 feet away from the base
unit. An LED ashes on the top of the module to let the customer know when the
module communicates with the handheld, as well as when the module’s battery is
low. The battery is rechargeable via the mini-USB connector on the top of the module.

NOTICE

(1) This device may not cause harmful interference. and (2) this device must accept
any interference received, including interference that may cause undesired operation.

Cet appareil est conforme à des règlements d’Industrie Canada exempts de licence
standard RSS (s). Son fonctionnement est soumis aux deux conditions suivantes:
(1) Ce dispositif ne doit pas causer d’interférences nuisibles, et (2) cet appareil doit
accepter toute interférence reçue, y compris les interférences pouvant entraîner un
fonctionnement indésirable.

This Class B digital apparatus complies with Canadian ICES-003.
Cet appareil numériqué de la classe B est conformé à la norme NMB-003 du
Canada.

CHARGING BATTERY

NOTICE

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 top 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.

This device complies with Industry Canada license-exempt RSS
standard(s). Operation is subject to the following two conditions:

It is required before the initial use of the module to fully charge the
battery for 12 hours.

Battery Removal:

If, for some reason, the wireless probe needs to be returned to Dwyer Instruments, Inc.
for maintenance or repair, the rechargeable lithium ion battery needs to be removed
prior to shipping the unit. Before attempting to remove the battery ensure the probe
has been powered down. To remove the battery, set the wireless probe face down
on a non-abrasive surface. There are four Phillips head screws that secure the two
halves of the handle together. Two are located under the serial number label at the
top of the probe and two are located at the bottom of the unit. When lifting the ends of
the serial label to access the screws be careful to not damage the label such that the
serial number cannot be read. Remove the four screws with a suitable Phillips screw
driver and set aside the back half of the housing. Remove the battery by grasping the

black plastic connector on the battery wire harness and pull straight out while securing

the black plastic connector on the circuit board with the other hand. Be careful to not
puncture the battery as this may cause a re. Remove the battery and set aside.
Securely replace the four screws to hold the handle of the probe together. The unit
may now be packaged for shipping back to Dwyer Instruments, Inc.
