Entering Your Own Formula - Tru-Test EC-10 User Manual

Switch the unit on. It will beep and show "EC10" in the display panel. If the battery
needs recharging it will beep 3 times and "lo" will display on the panel. The current
formula in use will be displayed next with the "+" part of the equation first (default
500) and then the "x" part second (default 140).
The kg DM/ha calculation will be displayed based on that formula and any other
readings stored in the memory.
The unit has one default plate equation (built into the chip and cannot be replaced
or edited) and one custom (user editable) equation. This equation is typically used
in New Zealand between April and September.

and management techniques, i.e. irrigated pasture. This research also provided
equations which more accurately reflect the physiological state of pasture - e.g.
vegetative versus reproductive state.
Examples:
The plate meter also provides an option for selecting your own equation or those
recommended by consultants, such as Dairy NZ or Beef + Lamb NZ. Your plate meter
will be set up for the Dairy NZ recommended equation for the autumn/winter
Dairy NZ formulas
months. See
While the plate meter is switched on, hold down the "Menu" button. The display
shows 'F_ _ d' Press "Enter". The display will then show (500) and then (140). The
default formula has now been loaded and saved to memory.
