stop. At the same time, the top heater's position is being adjusted, so the measured value
is not vibrating. After 1.5 periods of vibration, the PID self-setting is completed. Then the
AT lamp is off. The meter can calculate the best PID parameter and save it in the meter
according to the vibration period and amplitude.
If the system can't give vibrate response during the PID self-setting, the PID self-setting
can't finish successfully. As different systems have different response periods, the time of
PID self-setting ranges from several seconds to several hours. The time is affected by the
system, not the meter.
Don't change the settings during PID self-setting, because one change leads to one
restart, then PID time is prolonged.
When we use meters with the function of curve procedure control, we should stop
the curve procedures first, set the PID self-setting according to the above steps, then start
the curve procedure control.
If we only choose PID self-setting, please set the differential time to OFF so that it is
not changed when the meter is in the process of PID self-setting. In the system that
doesn't allow output signals change frequently, we should choose PID self-setting.
e. Problems display
When the input sensor breaks or the input signals exceed the max range, the upper
screen will show the fault code snb; when the sensor short-circuits, or the input signals is
less than the min range, the upper screen will show the fault code ur.
In general, the meter works in the state of auto-control. When the meter shows Snb or ur,
it shifts to start working very soon, outputting powers. Then, the power can be controlled
by button

,at the same time, the MAN lamp flickers. Once the problem is solved,
the meter will return to the state of auto-control.
