6.2 Input variables

Every measuring range is configured with the DIP switch as follows:
• Measuring range characteristic curve
- rising (e.g. 0 ... x)
- falling (e.g. 0 ... -x)
• Measuring range symmetry
- Symmetric bidirectional (e.g –x ... +x)
- Asymmetric unidirectional (e.g. 0 ... x)
• Unit in [mbar] or [Pa]
Measuring range
≤ -2.50 ... 2.50 mbar / -250 ... 250 Pa
≤ -10.00 ... 10.00 mbar / -1000 ... 1000 Pa
≤ -40.00 ... 40.00 mbar / -4000 ... 4000 Pa
≤ -100.00 ... 100.00 mbar / -10 ... 10 kPa
≤ -250.00 ... 250.00 mbar / -25 ... 25 kPa

6.3 Measuring accuracy

• Based on the reference temperature, the information only applies within the
compensation range.
• The characteristic curve deviation contains linearity, hysteresis and non-re-
petitiveness.
• Compensation range: -20 ... +70 °C.
• The information is provided for the rising measuring range characteristic
curve. They also apply for the falling characteristic curve.
