7.3.4 Using the *TST? Query
You can get the AC source to execute a partial selftest by sending it the GPIB *TST?
query command. These tests do not interfere with normal operation or cause the
output to change. The command returns a value of zero if all tests pass. Otherwise,
the command returns the error code of the first test that failed. No error codes are
displayed on the display and the AC Power Source will attempt to continue normal
operation.
7.4 Firmware Revisions
If needed, you can confirm the firmware revision of your AC Power Source with the
GPIB *IDN? query command. The Windows program supplied with the iL Series AC
source can be used to do this. Use the command line found in the Source interface
menu. Either IEEE-488 or RS232C can be used.
7.4.1 ROM Replacement
Instruments that are being initialized for the first time or have suffered non-volatile
memory corruption should be initialized with the front panel EEINIT command. To
initialize the unit perform the following:
•
Turn the unit on, then do the front panel CAL ON command.
•
Press 0 and 9 keys simultaneously, EEINIT <model> should now be displayed.
•
Scroll to the correct model number and press ENTER.
If the command is successful, the front panel display will go through a normal power-
on sequence.
7.4.2 ROM Update
It is possible to update to newer ROM versions without destroying the calibration
data. To update the unit to newer ROM revisions perform the following:
•
Turn input power off, remove the old ROM’s and install the new ROM’s.
•
Turn the unit on, then perform the front panel CAL ON command.
•
Press 0 and 9 keys simultaneously, then scroll to the ROMUPD command.
•
Scroll to correct model number and press ENTER.
If the command is successful, the front panel display will go through a normal power-
on sequence. If “OUT OF RANGE” error is displayed, then the instrument will have
to be re-initialized with the EEINIT command and re-calibrated. This can occur if the
instrument was previously initialized with a QA firmware revision (QA.xx.xx), or if the
non-volatile memory has become corrupted for any reason.
DANGER
Dangerous/Lethal voltages are present when the power supply covers
are removed.
