Authorized Service Center.
SENSOR : CALIBRATION EXPIRED Contact an Authorized Service Center to have the
sensor recalibrated. Check the time/date to make
sure it is correct.

BUTTONS: ... Check to make sure the buttons are not being
pressed. Cycle the power. Contact an Authorized
Service Center. Start-up Error Messages Error messages may appear after the self-test. If this happens, contact a Fluke Authorized Service Center for assistance. Downloading Recorded Data The thermo-hygrometer stores up to 400,000 readings in its memory. These readings can be downloaded to a computer using the RS-232 serial port.
The following steps should be followed to download logged data using the serial port: 1. Connect the thermo-hygrometer to a COM port on the computer using the serial cable. 2. Run a terminal program such as Windows(r) Terminal or HyperTerminal(r). a. Set up the terminal program to use the correct COM port and baud rate. Configure the communication settings to use 8 data bits, 1 stop bit, no parity and no flow control. b. If you want to save the downloaded data to a file, configure your terminal program to capture the incoming text and save it to a text file. Refer to your terminal program’s documentation for details on how to do this. 3. Begin downloading the data. a. Use the menu function DATA RECORD - DATA PRINT to begin sending recorded data uning text format. See Data Print. b. The thermo-hygrometer should immediately begin sending the data. If no readings have been stored, the thermo-hygrometer will not respond to these commands. 4. If the terminal program was set to capture the incoming data to a file, wait until no more data is being received, then stop capturing. The recorded data can also be transferred using the IR port with LogWare III software, or written to a file with a data card. Placement of IR Dongle for Transfer of Data The thermo-hygrometer can be used with the LogWare III software to collect data via the IR interface. Place your device near the IR port of the thermo-hygrometer between 3 and 6 inches (8 and 16 cm) and pointed directly at and perpendicular to the IR window. Check to make sure the buttons are not being
pressed. Cycle the power. Contact an Authorized
Service Center.
