A. LED INDICATOR

 Flashes once when the remote sensor

transmits a reading to the main unit.

 Flashes twice when battery power is low.

B. BATTERY COMPARTMENT

Holds 2 “AA” batteries

C. RESET

Resets all readings

D. CHANNEL SWITCH

Selects the desired transmission channel

from 1 to 3

E. WALL-MOUNT RECESSED OPENING

Attaches the remote sensor to the wall

NOTE:

Install the batteries and select the channel before mounting the sensor.

BATTERY INSTALLATION

 Remove the screws from the battery compartment with a small Phillips screwdriver.

 Set the channel 1 through 3. The switch is located in the battery compartment. Channel 1 is

typically selected if only one remote sensor is being used.

 Install 2 “AA” batteries (not included) matching the polarities shown in the battery compartment.

 Replace the battery compartment door and secure the screws.

 Secure the thermo-hygrometer remote sensor in the desired location.

MOUNTING

 The remote thermo-hygrometer sensor can be placed on the flat surface or mounted on the wall in

vertical position.

 Use the wall mount hardware and screws provided when mounting the thermo-hygrometer sensor

on the wall.

PLACEMENT TIPS:

 The remote thermo-hygrometer sensor should be placed in the area with a free air circulation and

sheltered from the direct sunlight and an extreme weather conditions.

 Ideally, place the thermo-hygrometer sensor above the natural surfaces (such as a grassy lawn).

 Avoid placing the thermo-hygrometer sensor near sources of heat such as chimneys and heating

elements.

 Avoid any areas collecting and radiating a heat from the sun, such as metal, brick or concrete

structures, paving, patios and decks.

 The international standard for the valid air temperature measurements is 4 feet (1.25meters)

above the ground.

screen

A. RAIN GAUGE BUCKET

Holds all rain gauge components

B. KNOB

Secures the top on the rain gauge bucket

C. RAIN GAUGE BUCKET FEET

Allows securing the rain gauge on its place

D. FUNNEL-SHAPED TOP WITH BATTERY COMPARTMENT

Contains battery compartment and rainfall counting electronics

E. BATTERY COMPARTMENT

Holds 2 “AA” size batteries

F. SCREWS

Secure battery compartment cover

G. BUILT-IN LEVELER

Allows leveling rain gauge on the surface

H. BUCKET SEE-SAW MECHANISM

Collects the rainfall in one of its containers and self-empties once full

I. PROTECTIVE SCREEN

Protects the rain gauge funnel from debris

BATTERY INSTALLATION

 Unlock the funnel-shaped top on the rain gauge by turning both knobs on the sides in a Counter-

clockwise direction.

 Remove the funnel-shaped top lifting it off the rain gauge bucket.

 Remove 7 small screws from the battery compartment cover using a small Phillips screwdriver

 Insert 2 “AA” batteries (not included), matching the polarities as shown in the battery compartment.

 Replace the battery compartment door and secure the screws.

 Insert the funnel-shaped top into the rain gauge bucket and secure it into place by turning the knobs

clockwise.

MOUNTING

 Make sure that the rain gauge bucket is level – check if the ball bearing inside the bucket is at the

midpoint of the leveler.

 Place the protective screen over the top to protect the rain gauge from the debris.

 Mount the rain gauge in place using mounting hardware provided.

 Make sure that the rain gauge is in open area where precipitation falls directly into the gauge’s

bucket, ideally 2-3 feet above the ground.

PLACEMENT TIPS

 The rain gauge should be placed in an open area away from walls, fences, trees and other

coverings, which may reduce the amount of rain collected in the bucket. Additionally, trees and

rooftops may be sources of pollen, leaves and other debris.

 To avoid rain shadow effects, place the rain gauge two to four times the height of any nearby

obstruction.

 It is important that excess rain can flow freely away from the rain gauge.
