To calibrate the TM43 Temperature Measuring Transducer, follow these steps:
1. Ensure that the device is powered off and disconnected from the power supply.
2. Locate the calibration adjustment screws on the device. These screws are used to adjust the zero point and span of the measuring range.
3. Use a suitable screwdriver to make the necessary adjustments. Turning the xxxx clockwise will increase the value, while turning it counterclockwise will decrease the value.
4. To adjust the zero point, apply the desired temperature to the sensor and adjust the xxxx until the output signal corresponds to the desired value (e.g., 0V or 4mA).
5. To adjust the span, apply a known temperature to the sensor and adjust the xxxx until the output signal corresponds to the desired value (e.g., 10V or 20mA).
6. Repeat the calibration process for each desired measuring range, if applicable.
7. Once the calibration is complete, reconnect the device to the power supply and verify that the output signal accurately reflects the measured temperature.
Please note that calibration should be performed by a qualified expert to ensure accurate results. The device is factory-calibrated, but an environmental precision adjustment by an expert is possible if needed.
