Power  up  the  third  remote  thermometer  as  described  in  Section  2.5.  Wait  until  the  sensor 
reports  to  the  console.  The  third  sensor  will  be  designated  as  Channel  3.  The  display  will 
switch between each sensor until you exit the initialization state by pressing any button.

Sensor Accuracy Note 

Verify  the  temperature  values  match  closely  with  the  console  and  sensor  array  in  the  same  location 
(about 10’ apart). The sensors should be within 4°F (the accuracy is ± 2°F). 
 
Allow about 30 minutes for both sensors to stabilize. 

4.6.3

 

Viewing the 3 Sensor Channels 

To view the 3 sensor channels, select the 

CH/+

 button. The minimum and maximum can be viewed 

for each channel as specified in Section 4.3. 
 

If  the  sensor  communication  has  been  lost  (blank  display  where  temperature  and  humidity  are 
displayed), hold the

 CH/+ 

key for 3 seconds to

 

re-acquire the current channel sensor signal. If you 

have additional remote sensors, hold the 

CH/+ 

key for 5 seconds to re-acquire all of the sensor 

signals.

Glossary of Terms 

Term 

Definition 

Absolute Barometric 
Pressure 

Relative barometric pressure, corrected to sea-level.    To compare 
pressure conditions from one location to another, meteorologists correct 
pressure to sea-level conditions. Because the air pressure decreases as 
you rise in altitude, the sea-level corrected pressure (the pressure your 
location would be at if located at sea-level) is generally higher than your 
measured pressure. 

Accuracy 

Accuracy is defined as the ability of a measurement to match the actual 
value of the quantity being measured. 

HectoPascals (hPa) 

Pressure units in SI (international system) units of measurement. Same 
as millibars (1 hPa = 1 mbar) 

Hygrometer 

A hygrometer is a device that measures relative humidity.    Relative 
humidity is a term used to describe the amount or percentage of water 
vapor that exists in air. 

Inches of Mercury (inHg) 

Pressure in Imperial units of measure. 
1 inch of mercury = 33.86 millibars 

Range 

Range is defined as the amount or extent a value can be measured. 

Relative Barometric 
Pressure 

Measured barometric pressure relative to your location or ambient 
conditions.
