1 Zero-point calibration condition: Under atmospheric pressure
2 When the measurement integration time is 250 ms, add ±0.006 kPa to the accuracy.
3 A value relative to the YOKOGAWA working standard
4 The data output interval through communication is the same as the display update interval.
5 Conditions of response time measurement:
• The time from when the change starts to when the value settles within ±1% of the convergence value.
• From the full scale value, 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
