2.3.7 Setting a Reference Value
Background
The REF# acts as an offset. The REF# value is subtracted
from the measured current (ACW, DCW) or measured
resistance (IR, GB).
Steps
1.
Press the UP / DOWN arrow keys to
bring the cursor to the
REF# setting.

Note
For GB tests, a reference offset can be automatically
created using the zeroing function. See page 39 for
details.
2.3.8 Setting the Test Time (Timer)
Background
The TIMER setting is used to set the test time for the
current test. The test time determines how long the test
voltage or current is applied to the DUT. This test time
does not include Ramp
, initial start time or discharge
time (note: GB does not have Ramp
or discharge
times). The test time can be set from 0.5 seconds to 999.9
seconds for ACW, DCW and GB and 1.0 second to 999.9
seconds for IR, with a resolution of 0.1 seconds for all
modes. The timer can be turned off when in the special
MANU test mode when using the ACW or DCW test
functions.
Each test has an initial test time of approximately 150ms
and a discharge time (except GB). The total discharge
time depends on the DUT and test voltage.
