◆ The maximum negative pressure depends on current barometric pressure and the ability of the internal pump to
generate this pressure. Meanwhile, the maximum pressure value depends on the control setting configuration (see
section 4.1). If the target pressure exceeds the limit, then the calibrator will error and allow for another pressure to
be entered.
◆ When target pressure exceeds current pressure range of the internal module, but is within the range of the second
internal module, it will switch to the applicable module.
4. Start /Stop controlling pressure
◆ The Calibrator will start controlling after the target pressure value is achieved.
◆ On the status of vent or measure, click or “control” button on the screen to start controlling to the target
pressure.
◆ Press or click “vent” and “measure” button on the screen to stop control.
5. Pressure stability
◆ When stable within the control settings, the displayed pressure value will change from white to green.
6. Auto step
◆ Press to enter into auto step setting interface, see parameter in figure 3-1:
Setting travel mode of auto step
Setting loop time of auto step
