The default value is NONE.
FILTER 01 through 08
Enter the lowpass filter time constant (in 10msec units) for each channel. Filter
times shorter than the update time are not usable. Update time can be calculated as:
The possible range is:
10 to 65535.
The default value is 10 (100msec).
JUNCTION COMP 01 through 08
Enter if the junction compensation will be from an entered fixed value or from the
Cold Junction Compensation channel. If channel 08 will be used as the Cold
Junction Compensation value, enter COLD for channels 01 through 07, and for
channel 08 also enter COLD. If the junction compensation will use the value
entered in the JUNCTION TEMP field, enter FIXED.
The valid values are:
COLD or FIXED
The default entry is COLD.
JUNCTION TEMPERATURE
Enter the fixed temperature at the junction of the thermocouple wire and the
terminals of the MTU.
Enter the estimated temperature at the MTU terminals if Cold Junction
Compensation will not be used by any one or all channels. If Cold Junction
Compensation will be used by all channels (01 to 07), then this field entry does not
need a value, leave it at the default of 0.
The possible entries are:
If the entry of the TEMP UNIT = C: -40...100
If the entry of the TEMP UNIT = F: -40...212
