Unichem Laboratories Training Officer Interview Questions, Process, and Tips

Calibration is the process of adjusting or verifying the accuracy of a measuring instrument or device.

• Calibration ensures that measurements taken by an instrument are accurate and reliable.

• It involves comparing the measurements of a device to a known standard.

• Calibration may involve adjusting the device to bring it in line with the standard.

• It is important in various fields like engineering, manufacturing, and scientif...read more

Calibrating temperature indicators involves adjusting them to ensure accurate readings.

• Calibration of temperature indicators involves comparing their readings to a known standard.

• Adjustments are made to the indicators to align their readings with the standard.

• Calibration may involve adjusting the zero point and span of the indicators.

• Examples of temperature indicators include thermometers, temperature sensors, and temp

Calibration of RTDs involves comparing the sensor's output to a known reference and adjusting it accordingly.

• RTDs (Resistance Temperature Detectors) are calibrated to ensure accurate temperature measurements.

• Calibration involves comparing the RTD's resistance values at different temperatures to a known reference.

• Adjustments are made to the RTD's output signal to align it with the reference values.

• Calibration can be don...read more

There are several types of flow meters used in various industries to measure the flow rate of fluids or gases.

• Some common types of flow meters include electromagnetic flow meters, ultrasonic flow meters, turbine flow meters, and positive displacement flow meters.

• Electromagnetic flow meters use Faraday's law of electromagnetic induction to measure the flow rate of conductive fluids.

• Ultrasonic flow meters utilize ultraso...read more

To check door interlock systems, inspect the physical components, test the electrical connections, and verify proper functioning.

• Inspect the door hinges, latches, and locks for any damage or misalignment.

• Check the wiring connections and ensure they are secure and not damaged.

• Test the interlock switch by opening and closing the door to see if it activates properly.

• Verify that the interlock system prevents the door from ...read more

To calibrate pressure gauges, vacuum gauges, and compound gauges, follow these steps:

• Use a known reference pressure source to compare the readings of the gauges.

• Adjust the gauges if there is any deviation from the reference pressure.

• Repeat the process multiple times to ensure accuracy.

• Document the calibration process and results for future reference.

• Perform regular calibrations to maintain accuracy.

• Example: For pressur...read more
