teMpeRatURe DiSpLaY MoDeS
Relative Humidity is show on the upper portion of
the display. Temperature is shown on the lower
portion of the display.
The following Temperature Display Modes are
available:
Current Temperature-
Shows the current temperature.
Dew-Point Temperature-
Shows the Dew-Point temperature. Indicated by td
appearing to the right of the temperature display.
Wet-Bulb Temperature-
Shows the Wet-Bulb temperature. Indicated by tw
appearing to the right of the temperature display.
Each press of the p or q button will cycle the dis-
play through the different temperature display modes.
DiSpLaYinG °f oR °c
To display the temperature readings in Fahrenheit
or Celsius, press and release the SET button. Each
press of the SET button will toggle the temperature
display between °F and °C.
RecaLL MaX/Min MeMoRY
To view the maximum and minimum readings,
press the MODE button. “MAX” appears on the
display to indicate the maximum readings recorded
are being displayed. Press the MODE button a
second time. “MIN” appears on the display to in-
dicate the minimum readings are being displayed.
If the high or low alarms have been activated, the
display will also cycle through the alarm set point
values. (See the “Alarms” section.)
The MAX and MIN temperature that is displayed is
dependant upon the temperature display mode that
has been selected (see the “Temperature Display
Modes” section). Pressing the p or q button
while displaying the MAX and MIN will cycle the
display through the different MAX/MIN temperatures
recorded (Current, Dew-Point, and Wet-Bulb).
If no buttons are pressed for 15 seconds, the
unit will return to the current temperature display
(“MAX” or “MIN” no longer appear on the display).
ReSet MaX/Min MeMoRY
While the MAX or MIN humidity and temperature
is being displayed (indicated by “MAX” or “MIN” on
the display), press the CLEAR button once. The
display will read “- - -“ and the reading will be set
to the current humidity and temperature readings.
The MAX and MIN readings may be reset indepen-
dent of each other. When reset, the humidity and
temperature readings (ambient, dew point, and wet
bulb) are reset to the current readings.
aLaRMS
High and/or low alarm points may be set for
either of the following units of measure: Humidity,
Temperature, Dew-Point Temperature, or Wet-Bulb
Temperature. A high alarm point and a low alarm
point, or both, may be set; however, the unit of
measure for the high and low alarm must be the
same. If the high alarm point is set for humidity,
the corresponding low alarm point (if used) must
also be for humidity. For example, a high alarm
point for humidity and a low alarm point for tem-
perature may not be set simultaneously.
High Alarm Set-Point (Ÿ ALARM) = An alarm will
sound when the reading rises above the set-point
Low Alarm Set-Point (” ALARM) = An alarm will
sound when the reading falls below the set-point
The user may enable/disable any or all of the
alarm set-points.
activate/De-activate the High/Low alarms
1. Press and hold the SET button until “” ALARM”
(low alarm) appears on the display.
NOTE: While setting, if no button is pressed for 15
seconds, the unit will automatically return to the current
humidity/temperature display.
2. Each press of the p or q button will toggle
the low alarm on or off.
"” ALARM OFF” indicates that the low alarm is not active.
“” ALARM ON” indicates that the low alarm is active.
3. Once the desired on/off status appears on the
display for the low alarm, press the SET button.
“Ÿ ALARM” (high alarm) will appear on the
display.
4. Each press of the p or q button will toggle
the high alarm on or off.
"Ÿ ALARM OFF” indicates that the high alarm is not active.
“Ÿ ALARM ON” indicates that the high alarm is active.
5. Once the desired on/off status appears on the
display for the high alarm, press the SET button.
The unit of measure to monitor will flash on the
display.
“%” = Humidity
°F or °C = Ambient Temperature*
td = Dew Point Temperature*
tw = Wet Bulb Temperature*
*The temperature unit of measure (°C or °F) will be
dependant upon the unit selected (See the “Displaying
°F or °C” section). The temperature alarm point will
automatically be switched to °F or °C based on what
has been selected.
6. Press the p or q button until the desired unit
of measure appears on the display.
7. Press the SET button, the unit will return to the
current humidity/temperature display.
When the low alarm and/or high alarm has been
activated, % ))) will appear at the top right corner of
the display.
Setting the alarm Values
Follow these procedures once the low alarm and/or
high alarm has been activated:
1. With the current humidity/temperature on the
display, press the MODE button 3 times. The
alarm set point will appear on the display.
“” ALARM” indicates low alarm
“Ÿ ALARM” indicates high alarm
NOTE: While setting, if no button is pressed for 15
seconds, the unit will automatically return to the current
humidity/temperature display.
2. Press and release the SET button. The alarm
set point will flash on the display.
3. Press the p or q button until the desired
value appears on the display.
Press and hold the button to rapidly change the display.
4. Once the desired value appears on the display,
press the SET button. The alarm set point will no
longer flash.
5. Press the MODE button, if both alarms have
been activated, the next alarm set point will
appear. Follow steps 2 through 4 to set the next
alarm set point value. If only one alarm has
been activated, the unit will return to the current
humidity/temperature display.
alarm Sounding
The alarm will sound and LED will flash when the
reading rises above and/or falls below the alarm
points that have been activated and set. The unit
will sound an alarm for up to one (1) minute as
long as the current reading is above and/or below
the alarm set point. The LED will continue to flash
as long as the current reading is above and/or
below the alarm set point. Once the reading
returns to an “in-range” condition, the alarm will
stop sounding and the LED will stop flashing. To
silence a sounding alarm, press any button.
“in-Range” alarm Setting
If the high alarm set point is lower than the low
alarm set point, the alarm will sound when the
reading is between the two alarm set points.
This allows an alarm to be set for an “in-range”
condition instead of an “out-of-range” condition.
For example, to have the alarm sound when the
humidity is within the range of 40% to 45%, set the
Low Alarm to alarm at 45% and the High Alarm to
alarm at 40%.
