General instructions
– If the thermometer is subject to large fluctuations 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 influence 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.
– Four lines will appear in line A if no thermocouple is connected.
– Lo or Hi will be displayed if the measured temperature is outside the measuring range.
– Only use the correct type of thermocouple (type K, J, T or E) and make sure that the device is set
to the corresponding type. The wrong type can cause significant measuring errors.
– In addition to being subject to ageing, a thermocouple is also greatly depending on the operating
conditions and should therefore be checked regularly.
– High pressure or mechanical deformation can change the grid structure and therefore have an influence
on the thermoelectric voltage output.
– The thermometer and thermocouples have different measuring ranges and accuracies and therefore
need to be considered separately.
