5.0 Transport, packaging and storage 5.1 Transport Check if the micro calibration bath shows any damage caused during transport. Report evident damages immediately 5.2 Packaging Do not remove the packaging until just before installation. Keep the packaging as it is the ideal protection during transport (e.g., if the installation site changes or if the product is shipped for possible repairs). - Page 15 After about 5 seconds activation has been completed and the calibration mode is automatically displayed. Mounted heating and cooling towers regulate micro-bath’s temperature automatically modifying the room temperature to match the adjusted nominal temperature on the regulator 6.4 Viewing the reference temperature and the nominal temperature Upper indicator The 4 digt –...

Page 21: Calibration (Calibration Mode)
Calibration of thermometers surface is very complex and not without ambiguities. The probe positioned on the surface of the heat dissipating surface producing a cold spot on the surface to be measured. In the micro-bath temperature calibration multifunctional calibration in a special cap surface it is generated to measure the temperature directly below the surface with a standard thermometer. - Page 22 The LED OUT 2 indicates the current reference. The nominal temperature appears in the lower display. Calibration mode indicator FAN or COOL Heating instrument The LED OUT 2 indicates the status of the output for fan control If the LED lights OUT 2 the fan rotates faster If it does not illuminate the LED OUT 2 the fan rotates at a slower speed Heating and cooling instrument The LED OUT 2 indicates the status of the output for regulating the cooling system...

8.0 Cooling micro-calibration bath WARNING RISK OF BURNS Before transporting or touching the micro-calibration bath it is necessary to ensure that it is sufficiently cooled because otherwise there is a risk of burns on both the micro-bathand the proof. To bring the micro-calibration bath from a high temperature to a low temperature as quickly as possible, the nominal temperature must be set to a lower temperature than ambient temperature. -
Page 24: External Cleaning
9.2.1 Cleaning micro-calibration bath Remove all the silicone oil from the trunk. Remove the trunk sensor basket and clean it, the magnetic stirrer applying water with lots of cleaning substances. Let all components dry. If distilled water is used remove the calibration liquid and allow the sensor basket dry, the magnetic stirrer and the trunk. - Page 25 10.0 Failures Causes Measurements Failure The reference sensor stops or is defective ---- Measured temperature below the limit value of the internal reference sensor (below the range-200 º C / -328 ºF ) Measured temperature above the limit value of the 0000 internal reference sensor (above the range + 850 º...
