- High BANDWIDTH: 3.5 ppm (that is a limit of 5 ppm for the maximum)

In order to determinate the setup values for PID regulation, we recommend to use the Ziegler-Nichols open loop method
(@>35541A6>;;>E9=7
- Connect a recorder to the analogic measurement output or write the reading measurement values for then to draw the graph f(time)
- Switch on the PID regulation in MANUAL mode
- Reach to and keep close the measurement value to the set point, adjusting the PID output
- Apply on ∆Cde a step of 10 % (for instance) on the analog output (Cde).
F1<?;5 if the value is 30%, apply 40%
- Note on the graph the corresponding timing T0
- ind on the graph both times t ant T such as ∆m= ∆Cde:
t = delay of response
T = Time corresponding to the same variation in % of measurement (∆m) and the analog output (∆Cde), ∆m= ∆Cde.
This value may be found out on the slope.
