4.2.5 Adjustment of Set Offset Value

Set offset value can be adjusted with set offset trimpot that is located on front panel.

When temperature is not equal to SET value, to remove the difference between SET value and

temperature and to make equal the temperature and SET value, Set offset is used. It can be

adjusted from -20% to 20% of full scale.

Minimum and maximum value of Set offset value according to the type and scale of the device are

given below:

SV-OFFSET

For PT-100 ( -100.0 to 100.0 )°C scaled devices : (-20.0 to +20.0)°C

For PT-100 ( 0.0 to 200.0 )°C scaled devices : (-20.0 to +20.0)°C

For PT-100 ( 0 to 400 )°C scaled devices : (-8 to 8)°C

For J Type TC ( 0 to 400 )°C scaled devices : (-8 to 8)°C

For J Type TC ( 0 to 800 )°C scaled devices : (-16 to 16)°C

For K Type TC ( 0 to1200 )°C scaled devices : (-24 to 24)°C

For R Type TC ( 0 to 1600 )°C scaled devices : (-32 to 32)°C

For S Type TC ( 0 to 1600 )°C scaled devices : (-32 to 32)°C
