Auto Sequence Group Test(press [AUTO] button less than 2 seconds)
The 287 unit will perform up to 10 groups of automatic test sequences and store the results in memory.
Groups are named 1 thru 0 where 0 is the 10th. Each group has 3 +decay, 3-decay, and an optional balance
test. The sequence can be set in the Set-Up Menu.
Decay test
: Zeroing to <5V, Charge to over +/-1050V, then Decay.
The decay timer starts at +/-1000V and stops at +/-100V.
Balance Test:
Zeroing to <5V, then Balance for the time duration. Start recording
Voltage peaks after 5 seconds.
The delay time between the tests can be set in the Set-Up Menu.
