Front-panel operation
Turn on the output
Press the OPERATE key after setting the appropriate voltage and current limits for
the DUT.
Select the current range
Select appropriate range:
battery channel (#1) = 5 A, 500 mA, 50 mA, or 5 mA
charger channel (#2) = 5 A
Set trigger level
TRIGGER LEVEL submenu
Before a RISING or FALLING pulse edge can trigger the start of a long integration,
the pulse must first be detected. TRIGGER LEVEL specifies the minimum pulse
level that will cause detection on the selected current range. For battery channel
(#1), all four current ranges can be used, and the trigger level setting
corresponding to the selected current range will be used to detect the pulse. For
the charger channel (#2), only the 5 A range is used for pulse measurements.
For battery channel (#1): Set the trigger level to either the 5 A, 500 mA, 50 mA, or
5 mA current range. For the 5 A current range, the trigger level can be set from 0
to 5 A in 5 mA steps. For the current 500 mA range, the trigger level can be set
from 0 to 500 mA in 0.5 mA steps. For the current 50 mA range, the trigger level
can be set from 0 to 50 mA in 0.05 mA steps. For the 5 mA current range, the trigger
level can be set from 0 to 5 mA in 0.005 mA steps.
The four trigger level ranges are displayed as follows using the TRIGGER LEVEL
menu option:
To change the trigger level setting for a current range, place the blinking cursor on
the "A" at the far right end of line two of the display, and press the
the desired current range is displayed at the beginning of line 2. After keying in the
trigger level (in amps), press ENTER to update the displayed trigger level setting
for that current range only.
5 A range:
