Metering motor – manual override/half-width drilling
Simply press the desired key(s).
The metering motor(s) can be stopped manually as desired, eg:
(a)
An area of field needs further cultivation before seeding.
(b)
In the case of a front-mounted hopper, the metering motor is switched off just before the end of the bout to clear the seed
through (the opposite of the ‘pre-start function).
(c)
You want to drill at half-width.

Product calibration
2.7.1 Initial product calibration
Set up the drill in the usual way for a bucket test.
1.
From the SETUP screen, press the key.
2a.
If the instrument is configured for dual products, first select the product you want to calibrate (fig.10).
Figure 10: Dual product/Single metering
2b.
Or if configured for dual metering, select the metering unit to be calibrated (fig. 11).
Figure 11: Single Product/Dual metering
3.
Otherwise, select the desired units then enter the weight required to be metered out (fig.12) and press ENTER. The metering
unit will then operate at the programmed calibration speed to dispense the correct amount of product, then stops. The
instrument then displays a weight figure
based on the existing programmed product calibration factor
.
NOTE: If a priming switch is employed for calibration the calibration routine will commence from fig. 13.
