Manual Calibration

A simple way to manually adjust the calibration values on a SmartReader Plus 6 thermocouple
logger follows. For each active channel:
1. Install the thermocouple and set the proper equation number for that thermocouple
type. Set the TrendReader software into Realtime mode.
2. Using a valid low reference temperature (as low as possible), observe the Realtime
reading and adjust the Low calibration value until the logger displays the reference
temperature.
3. Using a valid high reference temperature (as high as possible), observe the Realtime
reading and adjust the Mid calibration value until the logger displays the reference
temperature.
To obtain the best results from the calibration, set the reference temperatures as far apart as
possible.
