pulsed injection) are given to every one of the three
programmes.
There are independent EC and pH alarms, being
possible to configure the high value, the low one and
the delay in the detection of an irregularity.
Start and stop times are programmable for the
preagitation, agitation and alarm.
It is easy to use and programme by means of
three keys and a LC screen with 14 millimetre-high

Agrónic 54 follows the CE guidelines.
2. SCREEN DATA
Information is displayed on the screen in the
following way: the first two digits indicate the code in
which we are in. The following block of digits always
gives information about the electrical conductivity or
fertiliser 1, while the last block of digits makes
reference to the pH or fertiliser 2.
Use the “C” key to go from one code to the next
one. If you keep pressing this key, the code will
change rapidly.
Use the “+” and “-“ key to modify the values
which are displayed on the screen. These keys will
