OPERATION
46
Use the Numeric keys to enter the HI-Limit setting, then press the ENTER key. The
program will store the HI-Limit setting and advance to the LO-Limit parameter
automatically. The unit is M
W
and 1 M
W
per step.
Press the EXIT key to exit from the setting mode to the operation mode if all
parameters have been set.
2.3.4 LO-Limit Current setting
Advance the menu to the LO-Limit parameter. The display will show:
LO-Limit = XXXX M
W
Range : 1 - 9999
Use the Numeric keys to enter the LO-Limit setting, then press the ENTER key.
The program will store the LO-Limit setting and advance to the Delay Time
parameter automatically. The unit is M
W
and 1 M
W
per step.
Press the EXIT key to exit from the setting mode to the operation mode if all
parameters have been set.
2.3.5 Delay Time setting
Advance the menu to the Delay Time parameter. The display will show:
Delay Time = XXX.X s
Range : 0.5 - 999.9 0 = Constant
Use the Numeric keys to enter the Delay Time setting, then press the ENTER key.
The program will store the Delay Time setting and advance to the Scanner Channel
parameter automatically. The unit is second and 0.1 second per step.
Press the EXIT key to exit from the setting mode to the operation mode if all
parameters have been set.
Delay Time selects the time when the instrument will compare actual readings to the
HI-Limit and LO-limit settings. This delay allows charging current to stabilize
before a test judgment is made. The capacitance of the DUT will dictate what delay
setting is required to perform an accurate IR measurement.
If the Delay Time is set to 0, the test will continue until the RESET button is
pressed. The display will show the measured readings during the test. The timer
will continue to count the total test time and then will automatically reset to 0 and
start over.
