Each data point contains the temperature reading for P1, the temperature reading for P2, and the date and time of occurrence.

Note: All data stored in Celsius (°C) and date format is MM/DD/YYYY.

The thermometer will also store the most recent 10 alarm events. Each alarm event data point contains the probe channel 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.

VIEWING THE MEMORY CAPACITY

Slide the MEM VIEW switch to the ON position.

The rst line will display the current percentage of memory full. The second line will display the number of days

remaining before memory is full. The third line will display the logging interval (one minute).

USB ash drive into the USB port located on the left

side of the thermometer.

2. The download will begin automatically upon insert. The P1 LED will turn on to indicate the download process has begun.

3. Once the download process is complete, the LED will turn off. Do not remove the USB drive until the process is complete.

4. The data transfer rate is approximately 55 data points per second.

REVIEWING STORED DATA

The downloaded data is stored in a comma-delimited CSV le on the ash drive. The lename 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 the le starting with

the letter “A”.

If more than one le is written from the same thermometer to the USB ash drive, the revision letter will be incre-

mented in order to preserve the previously downloaded

les.

The data le can be opened in any software package supporting comma-delimited les including spreadsheet software (Excel) and text editors.

The le will contain the thermometer unique ID number,

the most recent ten temperature events, and all stored temperature readings with date and time stamps.

Note: All data stored in Celsius (°C) and date format is MM/DD/YYYY.

DISPLAY MESSAGES

If no buttons are pressed and LL.LL appears on the display, this indicates that the temperature being measured is outside of the temperature range of the unit, or that the probe is disconnected or damaged.

BENCH STAND

The unit is supplied with a bench stand located on the back. To use the bench stand, locate the small opening at

the bottom back of the unit. Place your ngernail into the opening and ip the stand out. To close the stand, simply

snap it shut.

POWER

The thermometer should be powered at all times with supplied AC adapter. In the event of a power failure, the backup batteries will power the thermometer for one week. A low battery symbol on the display indicates the AC adaptor has failed and the thermometer is running on the backup batteries.

BACKUP BATTERY REPLACEMENT

To replace the Backup Battery, remove the battery cover, located on the back of the unit by sliding it down. Remove

the exhausted batteries and replace with two (2) new AAA

alkaline batteries. Insert the new batteries with the proper polarity as indicated by the illustration in the battery compartment. Replace the battery cover.

Replacing the batteries WILL clear the minimum/maximum memories and high/low alarm settings. However, replacing the batteries WILL NOT clear the time-of- day/ date settings.

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.



Carefully, snap the two halves together with the looped

cable routed through the center.
