CHECKING
1) Terminal wiring: Check that all cables are correctly con-
nected according to the connection diagram.
2) Check DIP switch setting.
3) Power input voltage: Check voltage across the terminal
10 – 11 with a multimeter.
4) Input: Check that the input voltage is within 0 – 100% of
full-scale.
5) Output: Check that the load resistance meets the de-
scribed specifications.
6) Status indicator LED: Check that it blinks in the normal
patterns.

ZERO/SPAN ADJUSTMENTS
This unit is calibrated at the factory to meet the ordered
specifications, therefore you usually do not need any cali-
bration.
For matching the signal to a receiving instrument or in case
of regular calibration, fine zero and span adjustments can
be done to ±5% by pressing UP/DOWN switches enabled
with the zero/span selector switch. Calibrated values are
stored in the non-volatile memory, which will not be lost
even when you turn off power supply to the unit.
Zero and span are respectively set to 0% and 100% at the
factory.

Zero/Span Selector
ZERO: UP/DOWN switches usable for zero adjustment.
OFF: UP/DOWN switches unavailable.
SPAN: UP/DOWN switches usable for span adjustment.
UP/DOWN Switches
UP: Pressing UP increases adjusted values.
DOWN: Pressing DOWN decreases adjusted values.
■ HOW TO CALIBRATE THE ZERO
Slide the Zero/Span Selector to the bottom position and
press UP or DOWN switch. Incrementing speed will be
doubled when you keep pressing a switch.
■ HOW TO CALIBRATE THE SPAN
Slide the Zero/Span Selector to the top position and press
UP or DOWN switch. Incrementing speed will be doubled
when you keep pressing a switch.
■ HOW TO RESET
After you calibrated manually with these switches, you
can reset them to its ex-factory state by pressing both UP/
DOWN switches at once.
■ ADJUSTMENT PROCEDURE
Use a signal source and measuring instruments of sufficient
accuracy level. Turn the power supply on and warm up for
more than 20 minutes.
1) ZERO: Apply 0% input. Slide the Zero/Span Selector to
the bottom position. Press UP or DOWN switch and ad-
just output to 0%.
2) SPAN: Apply 100% input. Slide the Zero/Span Selector
to the top position. Press UP or DOWN switch and adjust
output to 100%.
3) Check ZERO adjustment again with 0% input.
4) The ZERO and SPAN adjustments are processed in a dig-
ital processor, and therefore they do not interact. Howev-
er, if ZERO value is changed, repeat the above procedure
1) – 3).
