Measurement range,
turndown ratio, zero
suppression, and zero
elevation
Lower range value (zero) and upper range value (100%) can be calibrated at any
value of pressure, provided that:
1. Their algebraic difference (the calibrated span) corresponds to an
authorized TDR.
2. Both are within the following acceptable limits.
Reference accuracy -
per IEC 770 and SAMA
PMC 31.1
The reference accuracy includes the effects of linearity, hysteresis, repeatability,
and deadband. This value is for transmitters with zero based spans, silicone oil fill,
and Hastelloy C-276 isolating diaphragms at a reference temperature of 25°C
(77°F). The value listed may vary depending on the URL and calibrated span of the
particular transmitter.
±0.20% of span or ±
(% of span), whichever is greater.
Stability per 12-month
period
±0.25% of URL at reference conditions
