Span limits

Maximum span = URL

For optimum measuring accuracy, it is recommended that

you select the sensor code which will provide the lowest

TD value.

Zero position suppression and elevation

The zero position and span can be set to any value within

the measuring range limits listed in the table if:–adjusted span ≥ smallest span

Damping

Configurable time constant between 0 and 60 s.

This is in addition to the sensor response time.

Turn On time

Ready for operation as per specifications in less than 10 s

with minimum damping.

Insulation resistance

>100 MΩ at 500 V DC (between terminals and ground).
