9-2. Operating the Analog IF Board
9-2-1. Setting the Voltage
When using the unit with a set voltage that is specified by an external resistance or voltage (hereinafter referred to as
the "externally set voltage"), the set voltage value represents the internally set voltage (set by the rotary encoder)
which is superimposed by the externally set voltage. While the CHECK key is lit in green, if the V key is unlit or lit in
amber, the voltage setting of the inte externally set voltage is displayed in the voltage indicator. When the V
key is lit in green, the voltage setting of the internally set voltage is displayed in the voltage indicator.
Operation procedure
Confirm that the power switch has been turned off.
1. Turn on No. 4 of SW 1, located on the analog IF
board. Use an external analog signal to set No.
5 and 6 of SW 1.

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
value, which is the internally set voltage
superimposed by the externally set voltage.
The current indicator displays the set current.

The V key is then lit in amber.
5. Press the V key again.
It then begins to blink green.
The internally set voltage is displayed (blinking) in
the voltage indicator.
6. Press the DIGIT

7. Turn the rotary encoder to modify the internally
set voltage.
The variable range of internally set voltage is
from -5% to +105% of the rated voltage.
The internally set voltage varies according to the
applied external signal.
