1. Connect the RS-232 cable that came with the 1523/1524 (DB9 to 3.5mm mini-stereo jack) to the computer and then to the 1523/1524. If your computer has only USB ports, we recommend to buy the serial to USB adapter and the Fluke part number for it is 2761737. We also recommend buying the TC adapter “2373-LTC”, and the Fluke part number is 3376729. For U.S. customers please send an email to orders@flukecal.com and for international customers please contact your local country authorized distributor to order these cables. You may also try purchasing locally an adapter 3.5mm mini-stereo jack to USB that MUST have a "FTDI chip".
2. Plug in 12V DC adapter to an electrical outlet and the other end into the 1523/1524.
3. Install the free 9940 IO Toolkit software from the CD provided or download it from:
https://www.fluke.com/en-us/support/software-downloads/io-toolkit-v10
4. Connect the 2373-LTC adapter to channel T1 on the 1523.
5. Connect the 2373-LTC adapter to channel 1 only on the 1524.
6. Turn on the 1523 or 1524.
7. Run the 9940 software.
8. Launch the 9940 software and the following message will appear on the screen, then click OK.
9. Then the following message will appear, click the icon on the right.
10. Click “no” on the following message.
11. Select the COM PORT where the 1523/1524 is connected to your computer then click OK. We recommend to use the "Windows Device Manager" tool to identify the COM PORT number.
12. Make sure the same baud rate is selected on your 1523/1524. To select the baud rate on your 1523/1524 do the following:
Press SETUP
Press the key “NEXT” twice to select “Instrument”
Press “ENTER”, view is highlighted
Press “ENTER”
Keep pressing the key “NEXT” until you get to “Baud Rate”
Use the arrows to select the baud rate then press “ENTER”
The recommended baud rate is 9600
Press SETUP

13. Click the icon “*IDN?”.
14. Click “No” on the following message.
15. In the command bar type *IDN? and then click enter.
16. You should receive a message similar to the one shown below. If not, close the program and reopen it again. Start again from step 8 and double check the COM PORT number set in the 1523 or 1524 matches the one from step 11.
17. Close the program and reopen it again, and the following window will show on your screen. Click on the icon located in the middle.
18. Make sure the 2373-LTC is plugged into the 1523/1524. Under "Probe Type" select Thermocouple and under "Conversion Type" select the TC type you want to use (see below). Enter the parameters as indicated below and then click on Upload, and internally the 1523/1524 will use the standard curve for the specific thermocouple you selected.
C0=0.0
C1=0.0
C2=0.0
C3=0.0
C4=0.0
RJTYPE= Double click and select "Internal"
RJTEMP= This is the ambient temperature where the 1523 or 1524 is located (°C)
MINOP= This is the lowest temperature for which this TC is rated (°C)
MAXOP= This is the highest temperature for which this TC is rated (°C)
C1=0.0
C2=0.0
C3=0.0
C4=0.0
RJTYPE= Double click and select "Internal"
