Operating the Reader
1. Press the
POWER
button to activate the reader. The message “READY” is displayed.
The reader is ready to take a reading.
2. Connect a sensor to the reader’s mating connector.
3. Press the
MEAS
button to start a measurement. The display shows “READING” while
the measurement is taking place. When the measurement is finished, the results are
shown. For GroPoint sensors, there will be a label indicating the type of
measurement, for example “MOIS” for a GroPoint Lite sensor’s soil moisture reading
and “TEMP” for its temperature reading. The table below lists the labels for the
various sensor types.
•
For devices that support multiple measurements, you may press the
NEXT
and
PREV
buttons to scroll through the list of available measurements. Scrolling past the last
measurement displays the first measurement again, and vice versa.
•
You may press and hold the
MEAS
button to take continuous readings from the
currently displayed measurement value. The display is updated with the new value
and the next measurement will be immediately started.

If any kind of communication error occurs, for example an attempt to measure with no
sensor connected, then the message “ERROR
NO SENSOR DETECTED” will be
scrolled across the screen. Check connections, then press the
MEAS
,
NEXT
or
PREV
button to return the unit to the “READY” state.
