The relative accuracy shown are expressed as absolute or % of rdg errors at -5°C to +40°C ambient temperature.
The maximum response time shown is referred to 90% signal changes.
The pressure relative accuracy shown is valid only after the auto-zero procedure.
Specifications may change without notice.
