equipment normally operates at 1700 °F, then perform the cold junction calibration using a 1700 °F
signal.
Firmware Version 1.09 and below
The user can source temperature to any one of the inputs, since the cold junction value is separate from
the input trim values, even though there is only one thermister per board. If the temperature being
sourced does not match the temperature displayed on the screen, the user will need to adjust the cold
junction value (“Modify brd CJ by (+/-) line) to match. After the cold junction value has been modified,
the user will be able to modify any of the input trims, if necessary.
Firmware Version 1.10 and above
Input Board Version 1.07 and below
The user will want to source the temperature to input three, since input boards with a version of 1.07 or
earlier only have one thermister, so the cold junction calibration will apply to the whole board. If the
temperature being sourced does not match the temperature displayed on the screen, then the user will
need to adjust the cold junction trim value to match. After the cold junction value has been modified,
the user will be able to adjust the trim values for inputs one, two, four, and five, if necessary.
Input Board Version 1.08 and above
The user will have to source the temperature to all five inputs, since input boards with a version of 1.08
or later have five thermisters per board, one for each input, so the cold junction calibration will have to
be made to each input separately. If the temperature being sourced does not match the temperature
displayed on the screen, then the user will need to adjust the input trim value to match.
24. System Setup
This screen displays any system setup information. Currently, the only information available is the
Survey Deviation Alarm Smart and the Temperature Resolution. To turn the Survey deviation Alarm
Smart on, enter a 1 and press Enter. To turn the Survey Deviation Alarm Smart off, enter a 0 and press
Enter. The Temperature resolution field accepts a 0, 1, or 2 as a value. The temperature resolution
affects the resolution of the temperatures displayed on the data logger.
