- During an auto-sensitivity procedure, the DEFAULT relay is forced to 0 so as
not to generate an alarm unnecessarily. The 4-20 mA signal switches to 0 mA.
12) Auto zero
- The auto zero allows the offset adjustment of the device according with its environment
where it is fitted (noise, electronic offset, …).
- When we arrive in this step, the SPX 100 asks :
- If the « VALID » key is pressed : next step without doing an auto zero.
- If the « right » key is pressed : beginning of the procedure auto zero. It’s automatic and
lasting 75 seconds. Wait the end of the procedure.
NOTE : - Unnecessary to put off the sensor.
- Unnecessary to stop the installation.
