Front Panel Pulse-current measurement procedure:
1. Set the output voltage and current limit.
2. Using the PULSE CURRENT selection of the MENU, set the trigger
level and delay (optional), integration times, and average readings
count (optional).
Important!
— For maximum transient performance, always use the
ENHANCED output mode, available from the OUTPUT RESPONSE
selection from the MENU and make certain the output sense leads are
connected across the load.
3. Press OPERATE.
4. Press the DISPLAY key and select the PULSE CURRENT display type.
5. Use the
and
buttons to display the desired pulse measurement:
PULSE HIGH, PULSE LOW, or PULSE AVERAGE.
NOTE:
With the output on, pulses will not be detected
if the trigger level is too low (an “A/D PULSE TRIG NOT DETECTED” or
“OVERFLOW” message will be displayed). Perform the following
procedure to find an appropriate trigger level.
Determining correct trigger level:
1. Turn the output on. If the trigger level is too low or too high, the “A/D
PULSE TRIG NOT DETECTED” message will be displayed briefly. If the
message does not appear, pulses are being detected, indicating that
the trigger level is valid. If so, it is unnecessary to complete this
procedure.
2. Go into the MENU, select PULSE CURRENT, then TRIGGER LEVEL.
3. Change the PULSE TRIG LEVEL and press ENTER. If the trigger level is
still too low or too high, the “A/D PULSE TRIG NOT DETECTED”
message will appear on the display again. It may take a few seconds for
the message to appear.
4. If the message appears, repeat Step 3 until a valid trigger level is found.
5. Use the MENU key to back out of the menu structure and display
pulse-current measurements.
