Span generation function
The span from 0 to 20mA or 4 to 20 mA (0 to 100%) can be switched with one touch. It is easy to adjust the span of the valve and check the operation of the valve.
Step generation function
The step can be generated by increasing or decreasing the step between 0 and 20 mA or between 4 and 20 mA in increments of 25% up to 100% with one touch, or stepwise automatically (step width is selectable) to improve work effi ciency. The Slow mode of Step Mode can also be used to change the step time in accordance with the performance of fi eld devices.
Sweep generation function
This function is used to increase or decrease the output value to the setpoint at the specifi ed ramp rate. It is possible to switch between Fast (15 sec) and Slow (40 sec) increase or decrease.

The CA450 can directly read the various sensor output signals (mV DC/AC) at any scaling. The units can be changed (16 units are available).Output signal and scaled value are simultaneously displayed.
