Diagnostic Test 7: Test parallel output
This test transmits data out the parallel TTL I/O port. The display prompts:
“dAtA”. Use the numeric keyboard to enter data. Press the ENTER key to
transmit the data. If the data is successfully sent, “ 1= xxx” is displayed, where
xxx is the first 3 characters of the data sent and 1= is the number of times that
the data has been sent. Press the ENTER key to send the data again. Press the
CLEAR key for the “dAtA” prompt. Enter new data to transmit or press the
CLEAR key to exit diagnostic test 3.
If the data is not successfully sent, the display will remain blank. If data is not
sent within 15 seconds, “Err 13” is displayed. Press the CLEAR key to exit from
the error display. The data will not transmit if the BUSY signal (TB4 pin 14) is
active (TTL high). Check the cable connections and the sending device.
Diagnostic Test 8: Test A/D
This test displays the (filtered) raw data being read from the A/D converter. Use
this test to determine optimum deadload and gain settings. If the number
displayed at deadload is less than 1000 or greater than 250,000 then use the
deadload offset (parameter 19) to add or subtract deadload from the signal input.
NOTE: deadload offset is automatically set using the calibration function 60. If
the full-scale number displayed is less than 380,000 then use the “loadcell mv/V”
parameter 1 to increase the gain. If the full-scale signal is greater than 1,000,000
then use the “loadcell mv/V” parameter 1 to decrease the gain.
If no data is being displayed, the A/D converter is “locked up”. Turn power off and
then on and re-activate the test. Check load cell wiring for reversed signal or
excitation signals.
Press the PRINT key to scroll the AD test function from:
1. Display raw data (digital filter on).
2. Display and transmit via serial port 2, raw data (digital filter off).
3. Display A/D drift. Press the ENTER key to clear the drift factor to 0.
Press the CLEAR key to exit AD test.
Diagnostic Test 9: Perform internal memory test
This test writes data to memory and then reads it back to test for failed memory
locations. The existing data in memory is not affected by this test. The display
prompts, “r TEST” while the test is in progress. The display prompts “PAS 32” if
the test is successful. If an error is detected the “Exxxx” is displayed, where xxxx
is the location of the error.
Diagnostic Test 10: Lamp Test
This test turns on all the LED displays and numeric display segments. Replace
any LED or display that does not illuminate. Press the CLEAR key to exit
diagnostic test 10.
