Probes characteristics
The temperature probes used are NTC 10K (10 kΩ at 25°C).
When the probe bulb is at the temperature of 25°C the electrical resi -
stance measurable at the probe ends is 10 kΩ.
The thermistor of these probes has a negative temperature coefficient:
the electrical resistance value decreases as the temperature increases.
To find out if a temperature probe is faulty or disconnected, check the
correspondence between the resistance value in kΩ and the bulb tem -
perature in °C according to the table.
For a reliable verify it is not necessary to check all the single values but
is enough to check some random values. If the instrument indicates
neverending resistance then the probe is interrupted.
