This setting is used to set the test time for a test. 
The test time determines how long the test 
voltage or current is applied to the DUT. This 
test time does not include RAMP UP time or 
RAMP DOWN time (note: GB and CONT do 
not have RAMP UP or RAMP DOWN). The test 
time can be set from 0.3 seconds to 999.9 
seconds for ACW, DCW, IR, GB and CONT, 
with a resolution of 0.1 seconds for all modes.  
Also, the test time can be turned off when using 
the ACW or DCW test functions.  
Each test has a RAMP UP and RAMP DOWN 
time (except GB and CONT), respectively. Refer 
to page 49 & 51 for more details.
