Allow the probe to reach the thermal equilib-
rium before taking any measurement. Reach-
ing thermal equilibrium can take several min-
utes. The greater the difference between the
temperature at which the probe was stored
and the temperature of the sample, the longer
the time will be.
If "----" is displayed, it indi-
cates that the D.O. probe is
not properly connected or the
temperature is out of range.
This also indicates the possibility of a broken
probe cable.
