Siemens 200 instruction manual P650 Offset Calibration, P651 Sound Velocity Calibration

P650 Offset Calibration

Calibrates Empty (P006) if the reported level is consistently high or low by a fixed amount.

Primary Index		Single Point Model		Dual Point Model
	Global		Transducer
Values	Range: -999 to 9999
	•	P006 Empty	•	P652	Offset Correction
Related	•	P062 Offset Reading	•	P664	Temperature
	•	P605 Zero Head

Before using this feature, verify the following parameters are correct:

•Empty (P006)

•Temperature (P664)

•Offset Reading (P062)

•Zero Head Offset (P605), if using OCM

Offset Calibration

Begin with a steady level.

1.Press TRANSDUCER to display the calculated reading.

2.Repeat Step One at least five times to verify repeatability.

3.Measure the actual reading (use tape measure).

4.Enter the actual value.

The deviation between the entered Empty (P006) value and the calibrated Empty value is stored in Offset Correction (P652).

P651 Sound Velocity Calibration

Changes the speed of sound constant.

Primary Index	Single Point Model		Dual Point Model
	Global		Transducer
Values	Range: -999 to 9999
Related	• P653	Velocity
	• P654	Velocity at 20°C

Condition for use of this feature

•The acoustic beam atmosphere is other than air

•The acoustic beam atmosphere temperature is unknown

•The Reading accuracy is acceptable at higher material levels only

For best results, calibrate with the level at a known value near empty.
