Adjusting The Pre-Programmed Calibrations; Optional External Moisture And Temperature Probes - Amphenol Protimeter Grainmaster i Manual De Instrucciones

2.1 Adjusting the Pre-Programmed Calibrations

If required, each of the 15 pre-programmed crop calibrations (i.e. all except the 0-100
scale) can be adjusted individually by ±1.5% to allow for subtle changes that can be caused
by crop variety, growing conditions or geographical region. Pragmatic users may choose to
adjust their meter to match the results obtained from a local instrument used commercially.
Whenever a user adjustment is active, the ! symbol flashes in the bottom right corner
