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.

• 50 – 100°C Span (90 – 180°F Span)

4) Adjust SW4 to the following positions:
 

SW4-1 :  ON 

SW4-2 :  ON

 

SW4-3 :  ON 

SW4-4 :  OFF

5) Adjust SW2 by 50°C unit and SW3 by 5°C unit according 

to Table below.  Total value of SW2 and SW3 is the tem-

perature span.

70°C.  Turn SW2-1 and SW3-4 ON.

 

[SW2-1] (50°C) + [SW3-4] (20°C) = 70°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.

LIGHTNING SURGE PROTECTION

M-System offers a series of lightning surge protector for 
protection against induced lightning surges.  Please contact
