With the power supply in command entry status
(:_:_:)
, press
MENU
until the top line of the
display presents the message
FS CURRENT (=_=_=) <n> mA
, where <n> represent the
actual full scale of the current (I
O
max or I
O
max/10); the bottom line reads
1=TOGGLE
. Press
ENTER
or
CLEAR
to exit menu without changing setting. Press
1
key to toggle between I
O
max
and I
O
max/10; press
ENTER
to accept new full scale current and exit menu or
CLEAR
to exit
without change.
When the full scale current is changed from High (I
O
max) to Low (I
O
max/10):
• programmed current value remains unchanged if it is less than or equal to the Low
maximum current, otherwise it is automatically limited to the Low maximum value.
• programmed overcurrent protection value remains unchanged if it is less than or equal
to 1.1 x Low maximum current, otherwise it is automatically limited to (1.1 x Low maxi-
mum).
• maximum current value (PAR. 3.2.12) is restored.
• voltage and overvoltage protection settings are unchanged.
• the 40 nonvolatile memory locations for Low range are active.
• Trigger, power up and reset current are divided by 10.
When the full scale current is changed from Low (I
O
max/10) to High (I
O
max):
• programmed current value remains unchanged if it is less than or equal to the High
maximum current, otherwise it is automatically limited to the High maximum value.
• programmed overcurrent protection value remains unchanged if it is less than or equal
to 1.1 x High maximum current, otherwise it is automatically limited to (1.1 x High max-
imum).
• maximum current value (PAR 3.2.12) is restored from saved value
• voltage and overvoltage protection settings are unchanged.
• the 40 nonvolatile memory locations for High range are active.
• Trigger, power up and reset current are multiplied by 10.
NOTES: 1. When changing from High to Low or Low to High range, even though the settings
for current and overcurrent are theoretically unchanged, they may actually be in
error by up to 0.15% of full scale current due to rounding errors. To improve accu-
racy it is recommended that current and overcurrent be set using the keypad after
changing range.
2. Changing current scale is not permitted when running a program (see PAR. 3.2.16).
All steps must use the same current scale.

SETTING OVERVOLTAGE OR OVERCURRENT PROTECTION
With the power supply in command entry status
(:_:_:)
, press
OV SET
(overvoltage) or
OC
SET
(overcurrent) to put the power supply in data entry status
(=_=_=)
. The lower right side of
the LCD shows the programmed setting in effect when the key is pressed. Press
ENTER
or
CLEAR
to exit without changing setting. Enter new value and press
ENTER
to accept new set-
ting (the
key erases data just entered), or
CLEAR
to exit without changing setting.
