2.0 Maintenance
2.1 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 and
adjustment.
Alternatively, you can calibrate/adjust the calibrator yourself.
You will need a calibrated, traceable sensor and thermometer with an
accuracy better than ±0.1°C / ±0.18°F (all MTC and CTC instruments
except CTC-1200 A), ±1.4°C / ±2.5°F (CTC-1200 A only) . Ensure
that the ambient temperature is 23°C±3°C / 73.4°F±5.4°F.
To calibrate/adjust the instrument five different temperatures are
needed. These are all preset in the various types of instruments.
The calibration temperatures are:
CTC-140 A / 1. -15°C / 5°F
MTC-140 A 2. 20°C / 68°F
3. 60°C / 140°F
4. 100°C / 212°F
5. 140°C / 284°F
CTC-320 A/B / 1. 50°C / 122°F
MTC-320 A 2. 120°C / 248°F
3. 180°C / 356°F
4. 250°C / 482°F
5. 320°C / 608°F
CTC-650 A/B / 1. 50°C / 122°F
MTC-650 A 2. 200°C / 392°F
3. 350°C / 662°F
4. 500°C / 932°F
5. 650°C / 1202°F
