1. If readings are read from ambient sensor, INT LCD
symbol will appear on display; If readings are read
from probe sensor, EXT LCD symbol will appear on
display.

Temperature Low Alarm -> External Temperature
High Alarm -> Exit Setup Mode.\
f. While in Setup mode, press and hold SET button
for 3 seconds to exit setup mode. Or while digits
are ashing, and no SET/▲/▼button pressed for
15s, the device will exit Setup mode.
g. While setting temperature and humidity alarms,
default step sizes are:
Temperature: 0.1
Humidity: 1
Data logging interval: 1 min
If press and hold ▲or ▼button for 2 seconds, the step
sizes are changed to following for fast adjustment:
Temperature: 1
Humidity: 10
Data logging interval: 10 min
Once ▲/▼button is released from long press, the step
sizes are back to default.
h. All setup items, time, alarm settings are stored
in the device’s memory, and will not be lost if the
device is powered off. While running, the device
stores time to memory once a minute.
ALARM
1. Once an alarm is triggered the corresponding
parameter will ash on LCD and alarm will beep.
2. Alarm will continue to beep for 60 seconds and then
will beep every 15 seconds.
3. Press CLEAR button to clear alarm, if both LCD
ashing and beeping on current display, INT or EXT.
If an alarm is triggered on both INT and EXT, press
CLEAR to clear alarm on current display, then press
SET/SEL button to select other display, and press
CLEAR button to clear the alarm.
4. If temperature or humidity falls back to normal range,
and then back to out of alarm range, alarm will be
triggered again.
SELECTING UNIT OF MEASURE:
1. Slide DISPLAY switch to MIN/MAX or ALM.
2. Press ▲(C/F) to select Celsius or Fahrenheit.
VIEW CURRENT MIN/MAX
1. Minimum values stored in memory are the minimum
readings measured since the minimum memory was
cleared. The maximum values stored in memory are
the maximum readings measured since the maximum
memory was cleared.
2. Min/Max values are not programmable; neither are
they stored in permanent memory. Min/Max values are
reset upon power cycle.
3. Slide DISPLAY switch to MIN/MAX position.
4. Current Min/Max values are displayed.
5. To clear current Min/Max values, while DISPLAY
switch is in MIN/MAX position, press CLEAR button
once.
VIEW ALARM LIMITS
1. Slide DISPLAY switch to ALM position.
2. Alarm setting are displayed on LCD.
ENABLE/DISABLE ALARMS
1. Slide ALM switch to ON or OFF to enable or disable
the alarms.
2. Alarms are enabled or disabled for all channels, can’t
be enabled or disabled individually.
DATA LOGGING OPERATION
1. Device will continuously log measurements from all
channels in memory in user-specied intervals. Each
data point contains humidity readings and temperature
readings.
2. Note: All data stored in %RH and Celsius. Date/time
format is MM/DD/YYYY.
3. Note: DO Not LEAVE USB Mass Storage Flash Drive
inserted in the unit. Insert, DOWNLOAD, and then
remove. Device cannot continuously write to a USB.
4. Device will also store the most recent 30 alarm events.
Each alarm event data point contains channel number
which alarmed, the alarm set point that was triggered,
the date and time the channel reading went out of
range, and the date and time the channel reading
returned to within range.
VIEW THE MEMORY CAPACITY/USAGE
1. Slide DISPLAY switch to MEM position
2. First line displays current percentage of memory full,
the second line displays the number of days remaining
before memory is full at the current data logging
interval, and the third line displays current date/time.
Note: For Excursion-Trac: the MEM symbol will become
active on the display when the memory is full. Once
memory is full, the oldest data points will be overwritten
with new data points.
For Memory-Loc: MEM symbol will become active on
display when the memory is 95% full. Once memory is
full, device will stop logging new data points.
CLEAR THE MEMORY
1. Slide DISPLAY switch to MEM position.
For Excursion-Trac: Press and hold CLEAR button
for 2 seconds until LCD displays “donEE”, then release
the button.
For Memory-Loc: Memory cannot be cleared.

Device cannot continuously write to a USB.
REVIEW STORED DATA
1. Downloaded data is stored in a comma-delimited CSV
le on ash drive. Filename naming convention is
“D1D2D3D4D5D6D7R1.CSV” where D1 through D7
are the last seven digits of the thermometer’s unique
ID number and R1 is the revision of le starting with
letter “A”.
2. If more than one le is written from same device to
USB ash drive, revision letter will be incremented to
preserve previously downloaded les.
3. Data le can be opened in any software package
supporting comma-delimited les including
spreadsheet software (Excel) and text editors.
4. File will contain device unique ID number, the most
recent 30 alarm events, and all stored temperature
readings with date and time stamps.
Note: All data stored in %RH, Celsius. Date/time format
is MM/DD/YYYY
DISPLAY MESSAGE
1. If no buttons are pressed and --.-- appears on display,
this indicates reading being measured is outside of the
operating range of device, or sensor is damaged
LOW BATTERY DISPLAY
If battery falls below 3.4V, Low Battery symbol will display
on LCD. Device checks battery voltage every two hours.
STATIC SUPPRESSOR INSTALLATION
Static generated, radio frequency can affect any cable
through the air or by physical contact. To protect against
radio frequency, install a suppressor onto your thermometers cable to absorb radio frequency as follows:
Lay the cable along the center of the
suppressor with the connector to your left.
Loop the right end of the cable under the
suppressor and back up again laying the cable along
the center of the suppressor.
