  • Page 11: Introduction

    Introduction CTC-calibrators are temperature calibrators designed to calibrate temperature sensors and temperature switches. Read this manual carefully before using the instrument and make sure that all safety instructions and warnings are observed. List of equipment received When you receive the instrument, the following should be enclosed: ...

  • Page 12: Safety Instructions

    Safety instructions Read this manual carefully before using the instrument! In order to avoid any personal injuries and/or damage to the instrument all safety instructions and warnings must be observed. Disposal – WEEE Directive These calibrators contain Electrical and Electronic circuits and must be recycled or disposed of properly (in accordance with the WEEE Directive 2002/96/EC).
  • Page 13  To ensure the connection to protective earth any extension cord used must also have a protective earth conductor.  Only use a mains power cord with a current rating as specified by the calibrator and which is approved for the voltage and plug configuration in your area.
  • Page 14 Never place a hot insertion tube in the optional carrying case.  Use only insulation plugs supplied by AMETEK Denmark A/S. Do not try to modify the insulation plugs to make them fit the sensor (CTC-1200 A only). About the fuses: ...
  • Page 15 Caution – Cold surface Below 0°C/32°F (applies only to the CTC-140 A models)  Do not touch the well or insertion tube when these are below 0°C/32°F - they might create frostbite.  If the calibrator has reached a temperature below 0°C/32°F, ice crystals may form on the insertion tube and the well.
  • Page 16 The humidity in the air may cause corrosion oxidation on the insertion tube inside the instrument. There is a risk that the insertion tube may get stuck if this is allowed to happen.  If the calibrator is to be transported, the insertion tube must be removed from the well to avoid damage to the instrument.

  • Page 17: Operating The Calibrator

    Operating the calibrator Before use Warning  The calibrator must not be used for any purposes other than those described in this manual, as it might cause a hazard.  The calibrator has been designed for indoor use only and is not to be used in wet locations. ...

  • Page 25: Setting The Main Voltage And Replacing The Fuses

    Setting the main voltage and replacing the fuses Warning  The fuse box must not be removed from the power control switch until the mains cable has been disconnected.  The two main fuses must have the specified current and voltage rating and be of the specified type.
  • Page 26 Remove the fuse box.  Remove both fuses and insert two new fuses. These must be  identical and should correspond to the line voltage.  CTC-140: 115V, 2AT = 105014 / 230V, 1AT = 105007  CTC-320/650: 115V, 10AF = 60B302 / 230V, 5AF = 60B301 ...

  • Page 27: After Use

    After use 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 carrying case after use, you must ensure that the instrument has cooled to a temperature below 100°C/212°F before placing it in the carrying case.

  • Page 28: Switching Off The Calibrator

    Switching off the calibrator The following routine must be observed before the insertion tube is removed and the instrument switched off (cf. fig. 1): If the calibrator has been heated up to temperatures above 50°C/122°F, you must wait until the instrument reaches a temperature below 50°C/122°F before you switch it off.
