Input Programming Pt100 only
If the input range is not listed in the programming
table, use the following formulae to work out the
Zero and Span DIP switch settings for gain.
deg C Span Gain = 1200 deg F Spain Gain = 2400
deg C High - deg C Low deg F High - deg F Low
deg C Zero Gain = deg C Low deg F Zero Gain = deg F Low
5 10
If Zero Gain is 1/ +ve Put S3-1 OFF (Positive Offset)
2/ -ve Put S3-1 ON (Negative Offset)
Note: Enter the Zero or Span gain value into the
appropriate Zero or Span DIP switch.
Input Range Programming Table Pt100 only.
Notes:1/ Switch status 1 = ON, 0 = OFF, X = DON'T CARE.
2/ Input ranges with '*' beside them require more adjustment by the Span trimpot.
SET TO '0' FOR CELCIUS. SET TO '1' FOR FAHRENHEIT.
Set to '0' for UPSCALE Sensor Break. Set to '1' for DOWNSCALE Sensor
Break.
TX802RTD ONLY
Set to '1' for UPSCALE Sensor Break. Set to '0' for DOWNSCALE Sensor
Break.
So if a gain value of 28 is required, put DIP switch No's 3, 4, 5 OFF
(ie, gains of 4 + 8 + 16 = 28) and all the other DIP switches ON.
Dip switches are accessed by seperating the two halves of the
enclosure
