18.6 Performance characteristics
Reference operating
conditions
• Error limits following ISO/DIS 11631
•
Water with +20 to +30 °C (+68 to +86 °F) at 2 to 4 bar (29 to 58 psi)
•
Specifications as per calibration protocol ±5 °C (±9 °F) and ±2 bar (±29 psi)
• Accuracy based on accredited calibration rigs that are traced to ISO 17025
To obtain measured errors, use the Applicator sizing tool(® ä 94)
Maximum measured error
In addition to the values indicated, the measured error at the current output is typically ±4 mA.
