9.1.2 Span limits
Maximum span = measuring range upper limit (URL)
To optimize performance characteristics, it is recommended
that you select the transmitter sensor code with the lowest
turn down ratio.
TURNDOWN = Upper range limit / set span
9.1.3 Zero suppression and elevation
The zero position and span can be set to any value within the
measuring range limits listed in the table if:
— Set span ≥ minimum span
9.1.4 Damping
Configurable time constant between 0 and 60 s.
This is in addition to the sensor response time, and can be
adjusted via the optional LCD indicator, handheld terminal, or
PC user interface.
9.1.5 Warm-up time
Ready for operation as per specifications in less than 10 s with
minimum damping.
9.1.6 Insulation resistance
>100 MΩ at 500 V DC (between terminals and ground).
