  • Page 7: 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 8  The ATC-125 contains the gases R-1270 and R-704 under pressure. The calibrator must under no conditions be stored or operated at ambient temperatures above 60C (140F). Doing so may cause a hazard. About the front panel:  For B versions only, the sockets on the input module must NEVER be connected to voltages exceeding 5V for the TC/RTD sockets and 45V for the mA/V sockets proportional to ground.
  • Page 9  AMETEK Denmark A/S does not take any responsibility, if the well is filled with other fluids than those recommended.  Liquid baths should only be operated by trained personal.  Heat transfer fluids must only be used in calibrators prepared as a liquid bath.
  • Page 10  Over 100°C/212°F If the calibrator has been heated up to temperatures above 100°C/212°F, you must wait until the instrument reaches a temperature below 100°C/212°F before you switch it off. Caution – Cold surface Below 0°C/32°F (applies only to the ATC-125/140/156/ 157 A/B models) ...

  • Page 16: Preparing The Dry-Block Calibrator

    Preparing the dry-block calibrator The ATC-B-version has a precision reference input. To achieve the high precision, a set of sensor coefficients relating to the specific sensor must be present in the ATC. Before use of the ATC, ensure that the correct coefficients in the ATC are equal to those from the sensors calibration certificate.

  • Page 18  Check the voltage on the power control switch (on/off switch (230V/115V)). If the voltage of the power control switch differs from the line voltage, you must adjust the setting of the power control switch as follows (see fig. 1a): Open the fuse box lid using a screwdriver.

  • Page 19: Choice Of Insertion Tube

    3.2.2 Choice of insertion tube Caution… Before using new insertion tubes for calibration, the insertion tubes must be heated up to maximum temperature - 250°C (482°F) / 320°C (608°F) / 650°C (1202°F) - for a period of minimum 30 minutes. In order to ensure the best calibration of your sensors please avoid using insertion tubes in the ATC-320 calibrator, which have been used in the ATC-650 calibrator.

  • Page 20: Inserting The Sensors

    3.1.3 Inserting the sensors Before inserting the sensors and switching on the calibrator, please note the following important warning: Warning  Never use heat transfer fluids such as silicone, oil, paste, etc. in the dry-block calibrator. These fluids may penetrate the calibrator and cause damage or create poisonous fumes.
  • Page 21 Caution…  The well and the insertion tube must be clean before use.  Scratches and other damage to the insertion tubes should be avoided by storing the insertion tubes carefully when not in use.  The insertion tube must never be forced into the well. The well could be damaged as a result, and the insertion tube may get stuck.
