IR Port Verification
Note
If you are using MET/CAL to do performance testing over the Meter’s IR
port, it is not necessary to perform this verification test.
1. Connect the Infrared Serial Cable to the USB port of a PC, with windows 98 or later,
and the Meter’s IR port at the top of the Meter.
2. Turn the Meter on, and set the rotary switch to any function.
3. On the PC, go to “Start”, and under Programs, Accessories, open “HyperTerminal”
4. Setup the following:
Name: 289, 287 IR Port Test
Connect using: ComX
Bits per second: 115200
Data bits: 8
Parity: None
Stop bits: 1
Flow control: None
5. Go to the Properties ICON on the tool bar.
6. Click on the “Settings” tab and leave the default settings.
7. Select “ASCII Setup:”
8. Set the following:
Send line ends with line feed
Echo typed characters locally
Append line feeds to incoming line ends
Wrap lines that exceed terminal width
9. Enter the identification command <ID> followed by carriage return (Enter)
10. The Meter should return the response: FLUKE 289, VX.XX, X, indicating the
model, software version, and serial number.
Note
If the PC indicates that the Meter is not connected, ensure that the COM
port is correct and that the IR Serial Cable is properly connected to the
Meter’s IR window.
Temperature Accuracy Test
Note
Prior to performing the following tests, the meter must be allowed to
stabilize to within
±
1
°
C of the ambient temperature. This could take
several hours depending on temperature gradient.
Connect K-type thermocouple and Fluke 80Ak to the temperature input on the Meter.
Connect the other end to the 5520A TC output. Allow connections to stabilize for two
minutes before proceeding.
