Channel Calibration - ACR Systems TRH-1000 Reference Manual

1.2.2.2

Channel Calibration

The Calibration subsection shows the Low, Mid, High, and Ext calibration values. These
values are used to adjust the readings of the logger in order to make the output more
accurate. To set each calibration value, click on the appropriate calibration field and enter the
value. The factory equations for the TRH-1000 use the Low and Mid values as offset and
span. High and Ext are not used.
Note that the calibration values are based on 255 increments between -5 and +5, the field will
default to the closest value of what is entered. E.g.: -4.9 will default to -4.8828125.
