readings. The # symbol indicates the active channel (see
Section 2
for details). For both
channels, the output state is indicated by:
• 0 (zero) if the output is OFF for that channel.
• l (lowercase L) if the output is ON for that channel..
•
PULSE CURRENT
- This mode is used to display high, low, or average pulse-current
measurements (see
Section 3
for details)
•
LONG INTEGRATION
- This mode is used to display average current measurements of a
pulse or pulses measuring periods between 850 msec to 60 sec (60 Hz line frequency) and
840 msec to 60 sec (50 Hz line frequency) (see
Section 4
for details).
•
DVM INPUT
(charger channel only)
- This mode is used to display the DC voltage applied to
the DVM input of the power supply (see
Section 2
for details).
Use the SAVE SETUP item of the MENU to save the selected display mode in memory, and use
the POWER ON SETUP item to specify the power-on setup (
Setups - Save, Power-on, and Recall
for details). The Dual V and I display cannot be saved. A reset will not change this setting.
Recalling a setup may change the setting. If setup recalling has a channel function set to
something other than voltage or current then this setting is disabled otherwise the setting is left
unchanged.
Selecting (enabling) Dual V and I will switch the function to voltage for each channel unless the
function is already voltage or current. Dual V and I will be disabled if you change the display mode
on either channel to be Pulse Current, Long Integration, or DVM Input (Channel #2 only).

4. With the desired mode and active channel displayed, press
ENTER

With DUAL V AND I DISPLAY mode enabled, there is no indicator on the front
panel about voltage protection or current limit state. See

for more
information on voltage protection and current limit.
