ATTENTION
The conversion speed of 2MLF-TC4S module is a cycle that the temperature
(electromotive force) entered into terminal strip is converted into digital value
and stored in internal memory.
Preciseness
The accuracy of 2MLF-TC4S module depends on the ambient temperature and is as
follows:
•
If the temperature measurement is 100
o
when the ambient temperature and K type
thermocouple is used, the output range of conversion data is between 100
o
- 2.6 ~
100
o
+ 2.6; that is, 97.4 ~ 102.6
o
.
ATTENTION
1. 2MLF-TC4S module is released from the factory after its offset/gain is
adjusted by using standard source of each channel. To maintain the
module’s accuracy, temporary changes to the values are strictly
prohibited.
2. 2MLF-TC4S module has different errors within temperature coefficient of
100ppm, each time the operation temperature varies by one degree
