Operation

Battery Low Warning, Installation and Replacement

1. When the icon appears in the display the batteries are weak and should be replaced. However, in-spec. measurements may still be made for several hours, after low battery indicator appears, before the instrument becomes inaccurate.
2. To replace or install batteries, remove the Philips head screw that secures the rear battery cover and lift off the cover.
3. Replace the six AAA batteries (use alkaline heavy duty type), observing polarity.
4. Replace and secure the cover.

Connecting thermocouples

1. Insert the Type K thermocouple mini-connector plug into the mini-connector socket on the bottom of the datalogger observing polarity (wide blade/narrow blade)
2. Up to three probes may be installed.
3. The temperature for inserted probes will be displayed T1, T2, T3 from top to bottom.
4. “——-“ will be displayed for open or unused inputs.

Datalogging

1. Open the left side door and insert a formatted SD card
   Note: The SD card should be at least 1GB in capacity.
   Note: Do not use memory cards formatted by other meters or cameras. Use the SD card formatting procedure under the advanced features section of this manual to correctly format the card.
   Note: The internal clock must be set to the correct time. See the advanced features section of this manual to set the clock.
   Note: The default data structure uses a decimal point “.” as the numeric decimal indicator. Seethe advanced features section of this manual to change this to a comma “,”.
   Note: If the SD memory card is not installed, “EMPTY” will appear in the display.
   Note: If the temperature probe is not installed, random numbers may appear in the data file.
   Note: If the temperature probe is not installed, after data download the temperature units symbol may not appear in the display.
   Note: Displayed error messages:
   The memory card is full or there is a problem with the card
   The battery is low and datalogging is disabled
   The SD card is not inserted

2. Press the LOGGER button for >2 seconds to begin logging. “DATALOGGER” will appear in the display (between T2 and T3 displays) and the meter will beep each time the data is recorded (if the beeper is enabled).

3. To stop datalogging, press the LOGGER button for >2 seconds. “DATALOGGER” will change to “DATA” and the meter will count down through the recorded data.
   NOTE: To avoid corrupting any data, do not remove the memory card without properly ending the record function.

Time/Date/Sample Rate Check
Press and Hold the TIME button for >2 seconds and the display will cycle through the date, time and sample rate information.

SD Card Data Structure

1. When the SD card if first inserted into the datalogger the folder TMC01 is created.
2. The first datalogging session will then create a file TMC01001.XLS. All data will be saved to this file until the number of rows reaches 30,000.
3. After 30, 000 rows a new file, TMC01002.XLS is created. This is repeated every 30,000 rowsuntil TMC01099.XLS. At this point a new folder, TMC02 is created and the process is repeated. TMC10 is the final folder.

Transferring Data to a PC

1. Remove the memory card from the datalogger and plug it into the SD card slot on the PC.
2. Launch Excel and open the data file on the memory card. The file will appear similar to the figure below.
   

Advanced Settings

The SET function is used to:

• Format the SD memory card
• Set the date and time
• Set the sampling time
• Set the beeper sound ON/OFF
• Set the SD card Decimal character
• Select the Temperature units
• Set the RS232 data output ON/OFF

1. Press and Hold the SET button for >2 seconds to enter the setting mode. The first function (Sd F) will appear in the display. Press the SET button to step through the seven functions. Use the ▲ and ▼ buttons to adjust the selected function. Use the “LOGGER” button to step through fields within a function. In the SET mode, if no button is pressed within 5 seconds the logger will revert back to the standard mode.
2. Sd F – Format the SD card. Press the ▲ button to select yES or no. For yES, press the Enter button. When yES and Ent appear, press the Enter key again to format the card and erase all existing data. The screen will display a flashing yEs and ESC while the memory is being erased and formatted.
