to an ATE system for automatic testing & calibration.

The auto-tune function allows the user to simplify initial setup for a
new system. A clever algorithm is provided to obtain an optimal set
of control parameters for the process, and it can be applied either as
the process is warming up ( cold start ) or as the process has been
in steady state ( warm start ).
Lockout Protection Lockout Protection
According to actual security requirement, a password is provided to
prevent the unit from being changed abnormally.

using its previous value as the sensor breaks. Hence, the process
can be well controlled temporarily as if the sensor is normal.
Digital Filter Digital Filter
A first order low pass filter with a programmable time constant is used
to improve the stability of process value. This is particularly useful in
certain application where the process value is too unstable to be read.
