1 When the measurement integration time is 250 ms, add ±0.006 kPa to the accuracy.
2 Excludes long-term stability of the zero point.
3 A value relative to the YOKOGAWA working standard
4 On models with the /F1 option, the measurement mode can be switched between normal, medium speed, and high speed.
5 The data output interval through communication is the same as the display update interval.
6 Conditions of response time measurement:
• The time from when the change starts to when the value settles within ±1% of the convergence value.
• From 0 kPa, open the input to the atmosphere (with the input section under no load).
• Measure using D/A output.
• When the measurement integration time is 1500 ms
