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.

5. 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.
