OPERATION
1.
Turn the meter on by sliding the OFF/ON/HOLD switch to the ON
position.
2. Slide the °F/°C switch to the desired position:
°F displays temperature readings in Fahrenheit.
°C displays temperature readings in Celsius
3. Slide the DEW/%RH/TEMP switch to the desired position:
DEW displays the Dew Point Temperature as the primary (larger) reading
and the Relative Humidity as the secondary (smaller) reading
%RH displays the Relative Humidity as the primary (larger) reading and
the Temperature as the secondary (smaller) reading
TEMP displays the Temperature as the primary (larger) reading and the
Relative Humidity as the secondary (smaller) reading
4. Turn the meter off by sliding the OFF/ON/HOLD switch to the OFF
position.
AUTOMATIC SHUTOFF (Disable)
To preserve battery life, the Automatic Shutoff feature (indicated by “ P”
appearing at the bottom middle of the display) will automatically shut the
meter off after 30 minutes if no switches have been used and no buttons
have been pressed.
To Disable the Automatic Shutoff feature:
1.
Turn the meter off by sliding the OFF/ON/HOLD switch to the OFF
position.
2. Press and hold the READ button and turn the meter on by sliding the
OFF/ON/HOLD switch to ON. “ P OFF” will appear on the display
indicating that the automatic shutoff feature has been disabled. (“ P”
will no longer appear at the bottom of the display) The automatic
shutoff feature is automatically enabled when the meter is turned on
unless the above procedure is followed.
HOLD FUNCTION
1.
Slide the OFF/ON/HOLD switch to the HOLD position to “freeze” the
display at the current reading (“ HOLD” will appear at the top of the
display).
NOTE:
a. Sliding the DEW/%RH/TEMP and/or the °F/°C switch while in the
Hold mode will show the desired value (Temperature, %RH, Dew
Point) for the “frozen” reading.
b. If the MEMORY button is pressed while in the Hold mode, the
“frozen” reading will be recorded in the data logger memory.
2. Slide the OFF/ON/HOLD switch to the ON position to return the display to
the current reading. (“ HOLD” will no longer appear on the display).
MANUAL DATA LOGGING
The data logger feature will store and retain up to 99 readings until they have
been cleared. The number at the bottom left of the display indicates how
many readings are currently stored in the data logger memory.
If desired, prior to recording additional readings into memory, clear the
existing data logger memory. (See the “Clearing the Data Logger Memory”
section.)
With the meter turned on and displaying the desired values, press the
MEMORY button.
Each time the MEMORY button is pressed, “ M” will appear to the left of the
display and the reading will be recorded in the data logger memory.
NOTE:
a. All readings (Temperature, Relative Humidity, and Dew Point) will be
stored into memory with each press of the MEMORY button,
regardless of the display mode.
b. If the MEMORY button is pressed while in the Hold mode, the
“frozen” reading will be recorded in the data logger memory.
Once the data logger memory is full (99 readings), “ FULL” will appear at
the top of the display when the MEMORY button is pressed. See the
“Clearing the Data Logger Memory” section to clear the memory so that more
data may be recorded.
DISPLAYING THE DATA LOGGER MEMORY
The data logger will store and retain the readings until they have been
cleared.
To view the readings stored in the data logger memory :
1.
Turn the meter on by sliding the OFF/ON/HOLD switch to the ON
position. The number of readings stored in the data logger memory will
be shown in the lower left corner of the display.
2. Pressing the READ button will scroll through the readings stored in the
data logger memory in order of newest to oldest (10, 9, 8, 7, 6... etc.).
“ R” will appear on the display to indicate that the value on the display is
a reading stored in the data logger memory.
NOTE:
a. While displaying the readings stored in the data logger memory,
sliding the DEW/%RH/TEMP and/or the °F/°C switch will show the
desired value (Temperature, %RH, Dew Point) for the recorded
reading.
b. Pressing the MEMORY button while displaying the readings stored in
the data logger memory will skip the readings in groups of 10 (98, 88,
78, 68... etc.)
3.
To exit from displaying the data logger memory, press and hold the
READ button for 3 seconds. “ R” will no longer appear on the display.
CLEARING THE DATA LOGGER MEMORY
The data logger will store and retain the readings until they have been cleared.
Once the maximum number of readings (99) have been recorded, the data logger
memory must be cleared in order to record more data.
