  • Page 19: Connecting Rtds

    4.2.1 Connecting RTDs 4-wire 3-wire 2-wire See section 10.0; Technical specifications for supported types of RTDs. The calibrator accepts 2-, 3-, and 4-wire inputs, with the 4-wire input being the most accurate. 4.2.2 Connecting Thermocouples and Voltages Sources See section 10.0; Technical specifications for supported types of thermocouples.
  • Page 20 Note… For best accuracy wait, as a minimum, 5 minutes after connecting the sensors, before any measurements are taken. Do not apply heat to the plugs while measuring the TC e.g. by touching them. The multi-scanner is also able to measure the mV of a thermocouple, which can be used along with a table if the corresponding TC type is not supported by the multi-scanner.

When in doubt, get the multi-scanner serviced. • When servicing the multi-scanner, only use specified replacement parts. There are no user serviceable parts inside the multi-scanner.

  • Page 25: Operation With Jofracal

    Operation with JOFRACAL Both A- and B-models are operated by means of the sensor test and calibration software, AMETEK Denmark A/S JOFRACAL. The program is included on the enclosed CD. For introduction and use of the program, the user is advised to read the user manual included on the CD.

  • Page 26: Remote Operation

    Remote operation The ASM can be remotely controlled using a PC terminal, or by a computer program running the calibrator in an automated system. It uses an RS-232 serial port connection for remote operation. With this connection the user can write programs on the PC, with Windows languages like Visual Basic to operate the calibrator, or use a Windows terminal, such as Hyper Terminal, to enter single commands.

  • Page 40: Adjusting The Multi-Scanner

    Adjusting the multi-scanner Adjusting and calibrating the instrument You are advised to return the instrument to AMETEK Denmark A/S or an accredited laboratory at least once a year for calibration and adjustment. • Alternatively, you can calibrate/adjust the instrument yourself using the AMETRIM Adjust and Calibration Software.

  • Page 41: Installing The Ametrim Software

    9.2.1 Installing the AMETRIM Software The software comes on a CD-ROM and is ready to run – no installation is required. Simply insert the CD-ROM and run the ATC- adjustment program. 9.2.2 Connecting the PC and the ASM-80x Caution… 1. Ensure that both the PC and the ASM-80x are switched off at the mains.
  • Page 42 Use the normal Windows procedure to start the AMETRIM software. If you are unsure of how to start software programs, refer to your Windows Help In the main menu select “Run Program” to start the calibration. Select “ASM-80x” and “Comport” in the “Device Quick Connect”...

  • Page 43: Run Calibration/Adjustment

    If the ASM-80x is not switched on or is not connected to the selected port, then the software returns to the AMETRIM adjustment software main menu. As the software starts, it detects the type of instrument connected to the PC and reads its serial number. This information plus the COM port the calibrator is connected to is displayed at the bottom of the AMETRIM window.
  • Page 44 For Cold Junction compensation, you will also require a stable temperature source, for example an ice bath, and a conversion table to provide the sensor’s corresponding µV value for the bath’s temperature. Note… Before calibrating/adjusting the inputs, the ASM-80x must have been turned on for at least half an hour.
  • Page 45 The number and type of electrical inputs to be checked is user- definable. You can also define if you want to check the inputs by just measuring them, adjust and calibrate or to measure, adjust and then calibrate the electrical inputs. Cold Junction compensation requires a special setup, using a calibrated thermocouple and temperature source, for example an ice bath.
