Page 12: Setting Up The Calibrator For Use
Setting up the calibrator for use Preparing the calibrator Warning • The calibrator has been designed for indoor use only and is not to be used in wet locations. • The calibrator is not to be used in hazardous areas, where vapour or gas leaks, etc. - Page 13 Ensure a free supply of air to the internal fan located at the bottom of the instrument (pos. 2). The area around the calibrator should be free of draught, dirt, flammable substances etc. Check that the fuse size corresponds to the applied voltage on (pos. 3).
-
Page 14: Choosing An Insertion Tube
Choosing an insertion tube Caution… To get the best results out of your calibrator, the insertion tube dimensions, tolerance and material are critical. We highly advise using the JOFRA insertion tubes, as they guarantee trouble free operation. Use of other insertion tubes may reduce performance of the calibrator and cause the insertion tube to get stuck. -
Page 15: Inserting The Sensor
These fluids may penetrate the calibrator and cause electrical hazard, damage or create poisonous fumes. • Never try to modify the insulation plugs to make them fit the sensor. Use only insulation plugs supplied by AMETEK Denmark A/S. 129375 06 2019-12-06... - Page 16 Insert the sensor as shown below in fig. 2. Fig. 2 Inserting sensor and Sensor under test insertion tube Insertion tube Thermal protection shield Check that the insulation plug fits the diameter of the sensor. Otherwise replace it (CTC- 155/CTC-1205 only). In order to spare the sensor and its connections it is recommended to use a thermal protection shield (129264) at high temperatures (CTC-652/660 only).

Page 35: Storing And Transporting The Calibrator
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. Warning • The calibrator must be switched off before any attempt to service the instrument is made. - Page 36 Fig. 5 Removing insertion tube Insertion tube Tool for insertion tube 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 37 Warning • Never leave hot insertion tubes which have been removed from the calibrator unsupervised – they may constitute a fire hazard or personal injury. If you intend to store the calibrator in the optional aluminium carrying case after use, you must ensure that the instrument has cooled to a temperature below 50°C/122°F before placing it in the carrying case.
