Front panel operation 19
Set trigger level and range
“TRIG LEVEL RANGE” and “TRIGGER LEVEL” sub-menus
Battery Channel (#1) — On the 5A current range, the trigger level can be set for either the
5A, 1A, or 100mA range.
Trigger level ranges: 5A range: 0–5A in 5mA steps
1A range: 0–1A in 1mA steps
100mA range: 0–100mA in 0.1 mA steps
“TRG LEV mA RANGE” and “TRIG LEVEL mA” sub-menus
Battery Channel (#1) (Models 2306-PJ and 2302-PJ) — On the 500mA current range, the
trigger level can be set for either the 500mA, 100mA, or the 10mA range.
Trigger level ranges: 500mA range: 0–500mA in 0.5mA steps
100mA range: 0–100mA in 0.1mA steps
10mA range: 0–10mA in 0.1mA steps
To change the range for the trigger level setting, place the blinking cursor on the “A” at the
far right end of line two of the display, and press the UP or DOWN key. After keying in the
trigger level (in amps), press ENTER to update the displayed range for that
trigger level setting
only.
Charger Channel (#2) — Set the trigger level from 0 to 5A in 5mA steps.
NOTE
This is the same as battery channel but settings are for only one range, the 5A range:
0–5A in 5mA steps.
If the trigger level is incorrect or the DUT is not functioning properly, the message
“LONG INT TRIG NOT DETECTED” will be displayed. (See the LONG INT TRIG NOT
DETECTED
note on
page 20
.)
Trigger edge – “TRIGGER EDGE” sub-menus
Toggle between the RISING, FALLING, and NEITHER settings with the UP and DOWN
keys.
With NEITHER selected, measurements will start as soon as the long integration function is
selected.
Timeout – “TIMEOUT” sub-menu
When the TIMEOUT value is reached, NO PULSE is displayed (top line of the front panel
display). The value for TIMEOUT should be set to a value greater than the long integration time
for a long integration reading.
Manually setting long integration time (“INTEGRATION TIME” sub-menu)
The value for LINT INT TIME for channel #1 or channel #2 can be specified in
0.850 sec
to
60 sec (i.e. @ 60Hz) with the UP and DOWN keys.
