Set trigger level and range
TRIGGER LEVEL - For the battery channel (#1), use to specify the trigger level for
the 5 A, 500 mA, 50 mA, or 5 mA current ranges. Pulse current only works on the
5 A current range for the charger channel. Pulses less than the specified level are
not detected.
Battery channel (#1): The following table shows the trigger levels for each current
range along with trigger hysteresis:

Trigger hysteresis is built into the hardware. If a pulse does not exceed the
appropriate hysteresis level, trigger detection will not occur. The trigger level
ranges for the battery channel (#1) are displayed as follows:
5 A range:
500 mA range:
50 mA range:
5 mA range:
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 two. After keying in
the trigger level (in amps), press ENTER to update the displayed trigger level
setting for that current range only.
Charger channel (#2): Set the trigger level from 0 to 5 A in 5 mA steps. However,
there is approximately 10mA of trigger hysteresis built into the hardware.
Therefore, if a pulse does not exceed this level, trigger detection will not occur.
If the trigger level is incorrect or the DUT is not functioning properly, the PULSE
CURR TRIG NOT DETECTED message will be displayed. (See note No Pulses
