■TEMPERATURE SPAN
• 100°C or Wider Span (180°F or Wider Span)
4) Adjust SW4 to the following positions:
SW4-1 : OFF SW4-2 : OFF
SW4-3 : OFF SW4-4 : ON
5) Adjust SW2 by 100°C unit and SW3 by 10°C unit accord-
ing to Table below. Total value of SW2 and SW3 is the
temperature span.

Example: For temperature range 50 – 180°C, span equals
130°C. Turn SW2-1 and SW3-3 ON.
[SW2-1] (100°C) + [SW3-3] (30°C) = 130°C.

■OUTPUT ZERO & SPAN ADJUSTMENT
1) ZERO: Apply 0% input and adjust output to 0% with the
VR1.
2) SPAN: Apply 100% input and adjust output to 100% with
the VR2.
3) Check ZERO adjustment again with 0% input.
4) When ZERO value is changed, repeat the above proce-
dure 1) – 3).
MAINTENANCE
Regular calibration procedure is explained below:
■CALIBRATION
Warm up the unit for at least 10 minutes. Apply 0%, 25%,
50%, 75% and 100% input signal. Check that the output
signal for the respective input signal remains within accu-
racy described in the data sheet. When the output is out of
tolerance, recalibrate the unit according to the “ADJUST-
MENT PROCEDURE” explained earlier.
