These cooling times allow technicians to perform calibration procedures with increasing and decreasing temperature sequences.
This is particularly useful when investigating temperature sensor hysteresis.
The actual cooling time depends on operating conditions and the thermal loading of the calibration block.
Short Stabilization Time
The AMETEK MTC-650 features a typical stabilization time of:
8 minutes
This describes the time required for the calibration block to stabilize under specified conditions.
The stabilization time of the device under test must also be considered.
Large temperature sensors or sensors with slow thermal response may require additional time before reliable measurements can be recorded.
For demanding calibration procedures, sufficient thermal equilibrium should be verified before recording the measurement results.
Excellent Radial Temperature Homogeneity
The AMETEK MTC-650 provides radial temperature homogeneity of:
0.1 °C
This specification describes temperature differences between calibration holes under defined conditions.
Good radial temperature homogeneity is particularly important when calibrating several temperature sensors simultaneously.
It helps minimize temperature differences between the reference thermometer and the devices under test.
The actual calibration uncertainty also depends on sensor geometry, immersion depth and thermal contact.
Interchangeable Calibration Inserts

Different insert configurations are available.
The appropriate insert should be selected according to the dimensions of the temperature sensor.
Good thermal contact between the sensor and insert helps reduce measurement errors.
Excessive clearance can increase temperature differences between the calibration block and the sensing element.
Automatic Temperature Stepping
The AMETEK MTC-650 supports automatic temperature stepping.
Users can define temperature setpoints and holding times.
The calibrator then performs the programmed temperature sequence automatically.
This function is particularly useful for repetitive calibration procedures.
Automatic stepping reduces manual intervention and improves calibration efficiency.
For maritime applications, technicians can prepare a calibration sequence and allow the instrument to complete the programmed temperature changes.
Automatic Temperature Switch Testing
The AMETEK MTC-650 supports automatic temperature switch testing.
Temperature switches are widely used in marine engines and industrial control systems.

The manufacturer specifies:
| Calibration Interval | Temperature Accuracy |
|---|---|
| 1 year | ±0.9 °C |
| 3 years | ±1.8 °C |
A longer calibration interval can reduce the frequency of equipment transportation and recalibration.
This is particularly useful for ships operating internationally.
However, the appropriate calibration interval must be determined according to the measurement requirements and quality management procedures.
A three year manufacturer specification does not automatically establish a suitable three year interval for every application.
