Dwyer Instruments WDPM-002 Specifications-Installation And Operating Instructions

The Series WDPM Wireless Differential Pressure Module transmits
measurements to the Model UHH handheld to view 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
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.
WARNING
Lithium ion batteries are very volatile and can cause a fire if
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).
