The sensor probe connector is
not fully inserted.
Fully insert the sensor probe connector.
The indication is
unstable (continued)
The sensor is not fully
contacting the object to be
measured.
Review the sensor measurement
procedures. If the object's thermal
capacity is small, the indication may be
affected by the protection tube size.
The instrument is used in an
environment where electrical
noise is generated.
Move the device to a place away from
electrical noise. Installing shields may
effectively block some electrical noises;
wrapping the main unit and each of the
sensor grip and cord with a sheet of
aluminum foil may also help.
