Dwyer Instruments WDPM Series Specifications-Installation And Operating Instructions

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
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.
This device complies with Industry Canada license-exempt RSS

CHARGING BATTERY

NOTICE It is required before the initial use of the module to fully charge the
battery for 12 hours.
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.
Lithium ion batteries are very volatile and can cause a fire if
WARNING
punctured or severely damaged. Only use a Dwyer Instruments,
Inc. approved charging device in a well ventilated area away from any flammable
materials or gases. Do not incinerate the battery. Only charge between 32 to 113°F
(0 to 45°C).
