6 LFD function
This module has an LFD function that can be enabled or disabled when performing TC measurement.
When enabled, 0.5 μA current is supplied and + side over range output occurs when the sensor is open
(at 300 kΩ or higher). (Over range detects the possibility
of a disconnection.)
NOTE
When LFD is enabled, a temperature rise error will occur from the power consumption in the
thermocouple (TC) resistance because a current of 0.5 μA is constantly supplied.
It can be disabled when performing standard measurement to reduce the above error.
When the setting is enabled, detection is possible when the open resistance is 300 kΩ or higher.
7 Maximum rated voltage to ground
9.5.5. Spare Parts
Two sets of temperature sensor connectors are included as standard, and they can be connected to an
alternate sensor in advance to allow easy changing.
