3-8 Pulse Current Measurements
• TRG LEVEL mA — Model 2306-PJ — Use to specify the trigger level for the 500mA
• TRIG LEVEL RANGE — Battery channel (#1) setting only. Use to specify the trigger
• TRIGGER LEVEL — Use to set the trigger level. Pulses less than the specified level are

current range (battery channel only). Pulses less than the specified level are not detected.
Battery Channel (#1): Model 2306-PJ — On the 500mA current range, the trig-
ger level can be set for 500mA, 100mA, or 10mA range:
500mA range 0-500mA in 0.5mA steps.
100mA range 0-100mA in 0.1mA steps.
10mA range 0-10mA in 0.1mA steps.
Trigger hysteresis is built into the hardware. For the 500mA range, trigger
hysteresis is approximately 1mA. For the 100mA range, trigger hysteresis is
approximately 0.2mA. For the 10mA range, trigger hysteresis is approximately
0.02mA. If a pulse does not exceed the appropriate hysteresis level, trigger
detection will not occur. The three trigger level ranges for the battery channel
(#1) are displayed as follows:
500mA Range: PCUR TLEV mA #1
mA (500) 0.0000A
100mA Range: PCUR TLEV mA #1
mA (100) 0.0000A
10mA Range:
PCUR TLEV mA #1
mA (10) 0.0000A
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
