How to change between posotive and negative preasure

The IFM PQ3 Series does not explicitly mention a direct setting to switch between positive and negative pressure. However, zero-point calibration ([coF] or [tcoF]) allows adjustment within -2% to 2% of the measuring span, which may help fine-tune measurements. Additionally, the system pressure setting ([SySP]) can optimize differential pressure measurement. If measuring both positive and negative pressures, ensure correct connections: low pressure to the auxiliary M5 port and high pressure to the G1/8 port.
