INPUT ALGORITHM

Standard or Custom

This prompt appears only if “CUSTOM INPUT” is
enabled under Enable Features in the Program
Mode Menu (Section 0). If “CUSTOM INPUT” is
disabled you will see the Standard prompts (Table
4-6).

Standard lets you choose a thermocouple, RTD,
EMF, or pyrometer type. The Standard prompts
are shown in Table 4-6.

Custom lets you convert the input from a
thermocouple or EMF to engineering units using a
custom curve containing up to 20 points.

Standard algorithm prompts

Table 4-6 describes all the prompts associated with the standard algorithm. These are the default
prompts for analog input programming. See Table 4-2 for additional prompts.

default type is OFF.

Input type (thermocouple, RTD, pyrometer)

RANGE LOW

The value must be within the limits
specified for the input type (see Table
1-3). Be sure to use the correct value
for the temperature units used (°F, °C,
K, °R). To enter the full range for the
temperature units selected (see
TEMPERATURE UNITS), select TYPE
again and press Enter without changing
the range type.

Low end of the input range.

RANGE HIGH

The value must be within the limits
specified for the input type (see Table
1-3). Be sure to use the correct value
