Hectaremeter Settings Setup
Refer to the installation and operation instructions supplied with
your hectaremeter kit (1) for information on installation, calibration,
operation and servicing (Fig 16).
Table 6 gives the effective working widths for the various
machines depending on the machine size and the row spacing.
The calibration procedure described in the hectaremeter
handbook involves accurately measuring the circumference of the
tyre and entering and storing this value in the meter. The effective
sowing width also needs to be entered. For measuring the tyre
circumference and obtaining the rolling circumference of the tyre
refer
Recalculating the Constan t (Page 16).
Note: If under certain operating conditions a calibration check
indicates a significant difference in the rolling circumference of the
tyre, the hectaremeter should be recalibrated by changing the H1
setting for the period of operation under those conditions.
