Setting up and running a test

Retrieving all test values
Stopping/aborting a test
Clearing protection events and errors
The unit requires a warm-up time of 1 hour for the measurement circuits to stabilize so that
the test results meet specifications. When the unit is fully warmed up, the front panel
light changes from amber to green. You can send programming commands to the unit while it
is warming up; you just cannot calibrate the unit.
Setting up and running a test
You need only one command to set up and run a test. For example, send:
INITiate:TEST:MATChed 75, 4.2, 2.8, 1, 1, 0.0001, 0.001, (@1:16)
This command matches the cell open-circuit voltage at the start of the test and runs according to the
following settings:
Test duration in minutes: 75
Maximum voltage: 4.2
Minimum voltage: 2.8
Output resistance in ohms: 1.0
Time interval in seconds: 1.0
Initial cell current in amps: 0.0001
Over-current protection in amps: 0.001
Cell channels: 1 through 16.
The test begins immediately after sending this command.
The front panel Test light flashes blue when cell matching has been initiated. The light stops flashing
and remains blue during the entire time the discharge test is running. After about 75 minutes, the test
will stop, the Test light turns off, and the final discharge values are stored in the unit until the host
computer reads the data out.
INITiate:TEST:PROBecheck and query sequence
The following initiates a probe check test and returns the status of the channel probes.
INITiate:TEST:PROBecheck (@1:16)
While(SENSe:PROBe:AVAIlable? == 0) \\ wait for data to become available
Sleep(1000);
FETCh:PROBecheck? (@1:16) \\ return comma-separated boolean values
