Adjusting and calibrating the instrument
You are advised to return the calibrator to AMETEK Denmark A/S or an
accredited laboratory at least once a year for calibration.
Alternatively, you can calibrate/adjust the calibrator yourself using the
AmeTrim-ATC Adjust and Calibration Software. This software is
divided into 3 separate processes:
Temperature Adjustment
: This checks the accuracy of the heat
source and internal sensor in the calibrator, (section 7.2.5).
Input Adjustment
: This checks the accuracy of the calibrator’s
electrical inputs (for B versions only), (section 7.2.6).
Reference Sensor
: This ensures that the electrical values from the
reference sensor correspond to the correct temperature values.
The calibration values of the sensor can be downloaded to the
calibrator. (B versions only), (section 7.2.7).
DTI Sensor
: Use this feature to manage the coefficients of the
sensors in an AMETEK Digital Temperature Indicator (DTI)
instrument.

Introduction to AmeTrim-ATC Software
This software is supplied on the AmeCal Temperature CD-ROM. It can
be run directly from this CD-ROM and requires no special installation.
It is possible to make a disk containing the AmeTrim-ATC software.
From this disk AmeTrim-ATC can be installed on the hard disk of the
computer, but the disk has to be in the disk drive when running the
software.
To use the software, you need:
Minimum hardware requirements for JOFRACAL calibration
software.
INTEL
TM
486 processor (PENTIUM
TM
800 MHz recommended).
32 MB RAM (64MB recommended).
80 B free disk space on hard disk prior to installation.
Standard VGA (800 x 600, 16 colours recommended).
CD-ROM drive for installation of the program.
1 free RS232 serial port.
