Series WDPM Wireless Differential Pressure Module for UHH/UHH2
Specifications - Installation and Operating Instructions
The Series WDPM Wireless Differential Pressure Module transmits
measurements to Models UHH and UHH2 or the Dwyer Mobile Meter
pressure drop across filters, static pressure in ducts, and velocity pressures from
pitot tubes or air flow stations. When using it with a pitot tube or air flow measuring
station, the measurement can be calculated to read directly in air velocity or
volumetric air flow. 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 flashes 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.

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.
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 fire. 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.
