3 Operating the Analyzer
What happens when a test is initiated?
Before initiating a test, wait for the Ready indicator to change from orange to green, which means the
unit is warmed up and ready for testing. It is possible to send commands and operate the unit prior to
the LED changing to green, but it is advisable to let the unit warm up to meet specified performance.
The LAN indicator flashes blue when any SCPI commands or queries are sent.
The Test indicator flashes blue when the cell matching process has been initiated and is running.
The Test indicator stops flashing and turns solid blue when the cell measurement test is running and
data logging is occurring.
The Test indicator turns off when the measurement logging has completed.
What happens when a test stops?
Normally, a test runs for the duration of its programmed test time and then stops. A test can also be
stopped before the completion of its programmed time by pushing the Stop button or sending an
Abort
command.
When a test stops or is stopped, the Test indicator turns off.
The Power, LAN, and Ready indicators are green. The Test and Error indicators are off.
What happens when the reference temperature exceeds its specification?
The Ready indicator turns orange when the internal reference temperature is slightly out of regulation.
There may be a problem with the airflow. Check that the airflow at the vents is unobstructed. Once the
internal temperature is restored, the Ready indicator will turn to green.
The Ready indicator flashes red when the internal reference temperature has increased to a point
where damage could occur. When this happens the internal heaters are disabled and the operating
temperature range will not be maintained. Turn the unit off, let it cool down, then turn it on to clear the
condition.
What happens when a protection event or error occurs?
The Error indicator turns red when either a protection event or an error has occurred.
If a protection event occurs on a channel, that channel is disconnected from the cell. You can continue
running the test on other channels. The channel that tripped protection remains disconnected from
the cell until protection is cleared.
If an error occurs, the instrument will continue to operate with errors present.
Clearing the protection event or error can only be done using the test program. There is no front panel
control to clear protection events or errors. Once the test program clears the protection event or error,
the Error LED turns off.
