If the temperatures are too close or the cuts are invalid
combinations, the instrument will not perform the TC
calculation and will advise you that a problem exists
by displaying “Auto Set Fail/Cuts Too Similar.
When to Use Method 1:
1. For first time calibration.
2. When temperature changes exist, but additional
grindouts are not possible, or practical, at other
temperatures.
When to Use Method 2:
1. When a second cut is possible at a different
product temperature. All oils change with the
temperature, no two oils change quite the same.
Some may change very little while some may
change considerably.
If real close measurement is not required, then
the effects of temperature changes may not be a
Set Point and Loop Calibration
The set point, delay, and loop span values are estab-
lished during programming. It is possible to adjust
these values without entering into the cut and TC cali-
bration programming. Entry of these values is de-
scribed in detail in the following sections.
Below is a flow chart programming guide. Each bubble
or diamond represents what the display will show. The
information adjacent to the small circles between the
bubbles instruct you on how to proceed through the
programming modes.

factor. But, it can be very important in cold cli-
mates where the maximum amount of water pipelines
will accept is often less than .5%. In these cases,
every possible variant must be considered and con-
trolled where possible. Reducing or removing the det-
rimental effects of temperature changes can often be
the difference between success or failure of an instal-
lation.
