Set according to the actual time, you need to set it manually every time you re-power on.
When the factory setting Y0.00=1, the time parameter will not be restored.
Note: The time and date are not saved when power is off.

Increased pump pressure offset
0 to 16.00Mbars
0.05Mbars
☆
Used to correlate the display value of the set pump pressure(Increase pump pressure display
value =Set pressure -Increased pump pressure offset)。
277
E8.07
Increase pump pressure display value
0 to 16.00Mbars
0.40Mbars
☆
Set a pumping pressure value. Only when the value is lower than this value and the frequency
is higher than the upper limit frequency, the pumping operation can be performed. Above this
value, it means that the pump is close to the target pressure and no pump is needed. This function
code is associated with E8.07. No need to set, you can set E8.07 separately.

☆
In the process of increasing the pump, after the power frequency is up, the time for the next
pump to run in frequency conversion is started.

☆
Used to correlate the display value of the set pump pressure(Reduce pump pressure display
