Press and hold the button as you switch the instrument on, and
continue to hold for (5 seconds) until the instrument enters the diagnostic
mode. The instrument displays "

A
Moisture Sensor input voltage

*A reading below 0.05V (50mV) indicates either
a faulty sensor or a bad connection, and
generates the error message "
Err.1
"
0.1V* - 5V
B
Temperature Sensor Input Voltage
[1]
*A reading below 0.05V (50mV) indicates either
a faulty sensor or a bad connection, and
generates the error message "
Err.2
"
0.1V* - 5V
C

Table 1: Diagnostic functions
[1]
For diagnostic mode only, display smoothing can be switched OFF (channel
F). The raw input voltages are displayed, and used to calculate the
temperature and Moisture Content displays. The display updates @ 2Hz to
ensure readability.
Display smoothing remains active for each channel in the Normal Operating
Mode, based on the settings for each channel in the Calibration Mode.
[2]
The calculated values displayed are for the grain type last selected in the
Normal Operating Mode.
