Explanation of Functions
1.1 Overview of the FX100
Measurement Input
DC voltage, thermocouple, resistance temperature detector, or ON/OFF signal (contact
signal or voltage signal) can be measured. The input signal is A/D-converted at a scan
interval and becomes a measured value of the channel. In addition, difference
computation, square-root computation, and scaling can be carried out on the measured
data to be a measured value of the channel. With the pulse measurement function (/
PM1 option), you can measure the number of pulses per unit time and pulse sum value.
Displaying the Measured Data
The measured data acquired to the internal memory can be displayed on the operation
display using trend waveforms, numeric values (digital values), or bar graphs.

Alarms
Alarms can be generated when the measured data meets a certain condition. When an
alarm occurs, you can have the information about the alarm displayed on the operation
screens. Also, you can output relay signals from the alarm output terminal on the option
terminal block (/A1, /A2, /A3 options). The overview display allows you to check the
alarm status on all channels. Also, the alarm summary shows detailed information about
the alarms in the order that they occurred.
