– If the thermometer is subject to large × uctuations in the ambient temperature, after the temperature
has stabilised, wait 20 minutes before performing a measurement.
– Always ensure adequate thermal coupling at the measuring point in order to avoid measuring errors
caused by temperature loss.
– Please note that all thermometers with a contact sensor in× uence the measurement and their thermal
capacity can reduce the actual temperature. More thermal energy should therefore be applied to the
thermocouple than it can dissipate.
– OL is shown in the display when no measuring sensor is connected.
– The thermometer shows OL when the measured temperature is outside the measuring range.
– Only use the correct types of thermocouple plugged in at the K-type connection; the wrong type of
thermocouple can cause considerable measuring errors.
– In addition to being subject to ageing, a thermocouple is also greatly depending on the operating condi-
tions and should therefore be checked regularly.
– High pressure or mechanical deformation can change the grid structure and therefore have an in× uence
on the thermoelectric voltage output.
