Page 99: After Use
After use Storing and transporting the calibrator Caution… The following guidelines should always be observed when storing and transporting the calibrator. This will ensure that the instrument and the sensor remain in good working order (all versions). Warning The calibrator must be switched off before any attempt to service the instrument is made.
Page 100 surfaces to oxidize. To prevent this from happening, the insertion tube and the well must be dried. This is done by heating up the calibrator to min. 100°C/212°F until all water left has evaporated. Remove the insulation plug while heating up. It is very important that humidity in the well and insertion tube is removed to prevent corrosion and frost expansion damages.
Page 101: Transporting The Dry-Block Calibrator
Caution – Hot surface Do not remove the insert from the calibrator before the insert has cooled down to less than 50°C/122°F. Caution… The insertion tube must always be removed from the calibrator after use. The humidity in the air may cause corrosion oxidation on the insertion tube inside the instrument.
Page 102: Transporting The Liquid Bath Calibrator
5.1.2 Transporting the liquid bath calibrator Warning Do not move the liquid bath calibrator containing hot fluid. When spilled the fluid might cause serious wounds. Before transporting the fluid it must be cooled down to a temperature near ambient. When the fluid has cooled down it is possible to move the liquid bath calibrator by hand.
Page 103 The following guidelines must be observed before emptying the well : Switch off the calibrator using the power control switch. Before handling the fluid, it must be cooled down to a temperature close to ambient. Remove the sensor basket and clean it with disposable paper towels.
Page 104: Replacing The Main Fuses
Replacing the main fuses Warning • The calibrator must be switched off before any attempt to service the instrument is made. There are no user serviceable parts inside the calibrator. • The fuse box must not be removed from the power control switch until the mains cable has been disconnected.
