Use this to enter the minimum head in units (P005) or as a percent of span.
P621 Auto Zero Head [6 relay model]
Calibrates Zero Head (P605) based on actual head measurements.
Primary Index
Values
Related
Use this parameter when the reported head is consistently high or low by a fixed amount.
Before using this feature, verify the following parameters are correct:
• Empty (P006)
• Temperature (P664)
• Offset Reading (P062=0)
• Zero Head Offset (P605)
Procedure, with "head" steady
1. Press TRANSDUCER
2. Repeat step ONE at least FIVE times to verify repeatability.
3. Measure the actual head (with a tape measure or solid rule).
4. Enter the actual head value.
The deviation between the entered Empty (P006) value and the calibrated Empty value is
stored in Offset Correction (P652). Alternatively, the Empty parameter (P006) can be
corrected directly.
