14.1 Temperature programs with Series 1 units

!
When temperature programs are run with rheome-
ters of Series 1 the thermal expansion of unit plus
sensor of about 1 micro meter per Kelvin have to be
taken into consideration.
E.g. with cone C60/1, which has a gap of 52 micron as stan-
dard value. If a temperature program is run from 20C to
80C , probably from a temperature of 72C on the cone will
touch the measuring plate and then drill a „hole".
The problem is avoided when plate-plate measuring sensors
with gaps of 0.7 to 1.5 mm are used instead of cones or the
function „ThermoGap" in the software is activated.
