9-2-3. Current setting
When using the unit with a set current that is specified by an external resistance or voltage (hereinafter referred to as
the "externally set current"), the set current value represents the internally set current (set by the rotary encoder) which
is superimposed by the externally set current. While the CHECK key is lit in green, if the A key is unlit or lit in amber,
the current setting of the inte externally set current is displayed in the current indicator. When the A key is lit in
green, the current setting of the internally set current is displayed in the current indicator.
Operation procedure
Confirm that the power switch has been turned off.
1. Turn on No. 7 of SW 1, which is located on the
analog IF board.
Use an external analog signal to set No. 8 and 9
of SW 1.
◆ For details, see “9-1-2. Wiring an analog
signal to the standard board” and “9-1-3.
Wiring an analog signal to IF-70PS”.
To switch over the dip switch, use a
needle-nosed tool such as a straight-slot
screwdriver.
2. Turn on the power switch.
3. Press the CHECK key, which is then lit in green.
The voltage indicator displays the set voltage.
The current indicator displays the set current
value, which is the internally set current
superimposed by the externally set current.
4. Press the A key while pressing and holding one
of the DIGIT

keys. The A key is then lit
in amber.
5. Press the A key again.
The key then starts to blink green.
The internally set current is displayed (blinking) in
the current indicator.
6. Press the DIGIT
▲ ▼
keys to move the
blinking digit in the current indicator.
7. Turn the rotary encoder to modify the internally
set current.
The variable range of internally set current is
from -5% to +105% of the rated current.
The internally set current varies according to the
externally applied signal.
