keys to scroll to the desired current range
trigger level (5 A, 500 mA, 50 mA, or 5 mA).
10. Use

or keys to scroll to the desired trigger level setting.
11. Press
ENTER
to select.
12. From
the
PULSE CURRENT #1/#2
item of the menu, set the
TRIGGER DELAY
(optional),
INTEGRATION TIMES
, and
AVERAGE READINGS COUNT
(optional).
13. Press
MENU
to exit the menu structure then press
OPERATE
.
14. Follow the instructions to select the pulse current display type in
Pulse current display
mode
.
No pulses detected
If no pulses are detected, current will not be measured
(i.e. -----A)
and the “NO PULSE” message
will be displayed. The “NO PULSE” message is displayed with dashes or the last valid pulse
reading. Dashes are shown if the pulse-current measurement settings are not appropriate for
detecting pulses. The last valid pulse is shown if the pulse disappears while taking readings and
no change in pulse settings was made.
Pulses are not detected with the output OFF. With the output ON, pulses will not be detected if the
trigger level is too low or too high. Perform the following procedure to find an appropriate trigger
level. Make sure the voltage and current settings are appropriate for detecting pulses.
NOTE
Pulse measurements for the battery channel are performed on the current range
selected (5 A, 500 mA, 50 mA, or 5 mA); pulse measurements on the charger
channel are automatically performed on the 5 A current range. On the battery
channel, the trigger level setting will automatically update to the trigger level
associated with the selected current range.
NOTE
Setting the trigger level with the output off will cause the pulse time-out message
to appear. However, the trigger level will be set.
