Operation check

The operation check is conducted to check the measurement
system with respect to the determinant measurement parameters
according to VDI 4206-2 via the test beds.
This operation check can also be conducted by the operator
outside of the regular checks, as required.
The operation check takes approx. 40 min and is split into 3
sections:
• Achieving system stability (approx. 10 min)
• Determining the transport uncertainty (15 min)
• Zero-point calibration (15 min)

Operation check
1. The measurement system stability check is carried out.
2. Start measurement:
- Diluter speed
The rotation diluter's revolutions per minute over 15 minutes are
displayed (while determining the transport uncertainty).
- Transport uncertainty
Over 15 minutes the cavities transported are counted and
compared to the setpoint value (setpoint = number of rotation
diluter cavities x number of rotations per minute x test duration).
In the event of a deviation of less than +/- 15 cavities, the
measurement system is fully functional.
- Zero-point calibration
Once the transport uncertainty has been determined, the zero
point of the sensor is stored and monitored over the next 15
minutes. In the event of a deviation of max. +/- 1.5 Hz, the
measurement system is fully functional.
- The operation check is assessed automatically by the
measurement system.
