1. INSTRUCTION
The meter is designed for measurement of temperature, relative humidity,
atmospheric pressure and pressure tendency. Measured values can be stored in
programmable interval into internal microSD CARD 4GB and transferred anytime
to a PC.
Measured values are displayed on a three line LCD display. The meter
compares all measured values (temperature, humidity, air pressure and dew
point temperature) with two adjustable levels for each measured quantity.
Breaking the level is indicated bythe correct values flashing on the display and
by audio indication (switchable). Meter is equipped with maximum and
minimum with time stamp memory function.

4-2 Description of Display:
ALM
SET HOLD
A: Datalogging mode indication.
M: Appears once data is stored into the memory.
M: Manual memory address number indication.
R: Read mode indication.
R: Recall manual memory address number indication.
MXt: Temperature maximum value indication.
MNt: Temperature minimum value indication.
YlM d-h m:s : Real-time or MX/MN recorded stamp time indication.
Td: Dew point temperature indication.
If air is cooled and gaseous water vapor begins to condense in the liquid
phase, the temperature at which condensation occurs is defined as the
dew point temperature.
Td/f: Dewpoint / Frostpoint Temperature indication.
When the dew point falls below freezing it is called the frost point
temperature. Where air is cooled enough to become saturated, but
forms ice instead of dew.

T: Difference of T and Td/f (T=T-Td/f) indication.
Tw: Wetbulb temperature indication.
Traditionally, the wet bulb temperature is the temperature indicated by a
thermometer wrapped in a wet cotton sheath.
а: Absolute humidity indication.
Absolute humidity refers to the mass of water in a unit volume of moist air
at a given temperature and pressure.
h: Enthalpy indication.
Enthalpy is the amount of energy required to bring air to its current state
from a dry air at 0℃.
HI: Heat Index indication.
The Heat Index is determined by using the dry bulb temperature and relative
humidity.
It is based upon charts available from the U.S. National Weather Service.
The Heat Index represents how an average person feels relative to climate
conditions. For a given temperature, the higher the humidity, the higher the
heat index.
The Heat Index is defined over a temperature range of 70℉to 120℉(21℃
to 49℃) and a relative humidity range of 30% to 99%. Outside of this range,
the meter will show dashes in the display for the Heat Index.
Humdx: Humidex indication.
The Humidex, used primarily in Canada, works on the same concept as
the Heat Index. The values are slightly different. The Humidex is
defined over a temperature range of 70℉to 109℉(21℃to 43℃) and a
relativehumidityrange of 20% to99%. Outside of this range, the meter
will show dashes in the display for the Humidex.
g/m³, gr/ft³: Absolute humidity units.
kJ/kg, Btu/lb: Enthalpy units.
℃, ℉: Temperature units.
P3h: Pressure tendency indication.
Pressure tendency is the difference between actual pressure and pressure
3 hours before. If the meter is not turned ON for at least 3 hours, the meter
will show dashes in the display for the P3h. Interval of refresh of pressure
tendency display is 5 minutes.
X: Mixing ratio indication.
Mixing ratio is the ratio of water vapor mass to the mass of dry gas.
