12. Unit Conversion

12.1.

Temperature (degree C)

12.1.1. F = engineering value *1.8 +32

12.1.2. K = engineering value +273.1

12.1.3. R = engineering value *1.8 +491.67

12.2.

Velocity (inch per second)

12.2.1. m/s = engineering value * 0.0254

12.2.2. mm/s = engineering value *25.4

13. Performance

13.1.

Power-up

Power up is less than 5 seconds. Analog 4-20 output is stable in less than 10 seconds. This device has no special

requirements for the reset and power-down process.

13.2.

Command Response Times

Minimum

-15ms

Typical

-25mS

Maximum

-75mS

13.3.

Channel update time period

Typical

-250mS

13.4.

Non-Volatile Memory

The devices configuration parameters are stored in EEPROM. New data is written to this memory immediately on

execution of a write command.

13.5.

Modes

Fixed current mode, using command 40 is cleared by power loss or a reset command 42.

13.6.

Damping

Command 34 Damping is standard and affects only the PV and the loop signal. Additional damping is available

using device specific command 129, parameter “detector time constant”. This damping affects PV, SV and TV and

can be changed per channel.

13.7.
