Temperature Input Units
Section 7-5
2. When an off-wire condition is detected, the display data will be 7FFF.
(In 1/100 Display Mode, the display data will be 7FFF FFFF.)
CRT1-TS04P Data Ranges
Note 1. If the Unit is subjected to sudden temperature changes, moisture may con-
dense in the Unit and cause incorrect indications. If there is condensation,
remove the Unit from service and keep it at a steady temperature for about
1 hour before using it again.
2. If the input temperature exceeds the convertible range, the temperature
data will be clamped at the minimum or maximum value.
If the temperature exceeds the convertible range by a certain value, an off-
wire condition (broken or disconnected input wire) will be detected and the
temperature data will be set to 7FFF Hex. If the input temperature returns
to the convertible range, the off-wire detection function will be reset auto-
matically and normal conversion data will be stored.

Cold junction compensator
Adjusts the input temperature. Do not touch or remove
the compensator. The correct temperature data will not
be displayed if the compensator is disturbed.
