seconds. Special versions are available which allow faster turn on for special 
applications such as spot welding. Check here for list of recorded SP versions made 
over the last 30+ years. See here for a list of available SP versions. 

To check the response time, input a step change to the control input and measure the 
time taken to reach the desired output. 

10. MI, MV, MP

 

The standard controller configuration outputs 0-1mA and calibration is performed on the 
meter side while the output is at maximum and measured using a current, voltage, or 
power meter
