How to use the peak hold function on Yokogawa UT52A?
The Yokogawa UT52A is a versatile and reliable instrument widely used in various industrial and measurement applications. One of its notable features is the peak hold function, which can be extremely useful for capturing and analyzing transient events. As a supplier of the Yokogawa UT52A, I'm here to guide you on how to effectively use this peak hold function.
Understanding the Peak Hold Function
The peak hold function on the Yokogawa UT52A allows you to record and display the maximum value of a measured signal over a certain period. This is particularly valuable when dealing with signals that have short - lived peaks, such as in electrical circuits with sudden voltage spikes or in mechanical systems with brief force surges.
In practical terms, imagine you are monitoring the voltage in an electrical power distribution system. There may be occasional voltage peaks due to sudden load changes or electrical disturbances. By using the peak hold function on the UT52A, you can capture these peaks, which might otherwise go unnoticed during normal continuous monitoring. This helps in detecting potential issues, ensuring the safety and stability of the system, and also in conducting accurate performance evaluations.


Activating the Peak Hold Function
Activating the peak hold function on the Yokogawa UT52A is a straightforward process. First, turn on the instrument and ensure that it is properly connected to the device or system you are measuring. Follow the standard connection procedures, such as connecting the appropriate probes for voltage or current measurements.
Once the instrument is powered on and connected, look for the dedicated "Peak Hold" button on the front panel of the UT52A. On most models, this button is clearly labeled. Press the "Peak Hold" button, and you will notice that the display will change to show the peak value of the measured signal.
Some users may be concerned about accidentally activating or deactivating the function. To prevent this, the UT52A has a clear indication on the display when the peak hold function is active. This way, you can always be sure that you are getting the correct peak - held values.
Using the Peak Hold Function in Different Measurement Scenarios
Electrical Measurements
In electrical measurements, the peak hold function can be used to detect voltage spikes in power supplies, which could potentially damage sensitive electronic components. For example, if you are testing a new power adapter for a computer, you can use the UT52A with the peak hold function enabled. Connect the probes to the output of the power adapter and start the test. As the power adapter is subjected to different loads, any sudden voltage peaks will be captured by the peak hold function.
You can also use it in measuring current surges. In a motor - driven system, when the motor starts, there is often a high - current inrush. By using the peak hold function, you can accurately measure the maximum current value during this inrush period. This information is crucial for sizing the appropriate fuses and circuit breakers to protect the motor and the electrical system.
Temperature Measurements
When it comes to temperature measurements, the peak hold function can be used to monitor sudden temperature changes. For instance, in a manufacturing process where materials are heated and cooled rapidly, the UT52A can be used to measure the temperature of the materials. By enabling the peak hold function, you can record the maximum temperature reached during the heating phase. This helps in ensuring that the materials are not over - heated, which could affect their quality and properties.
If you are interested in other Yokogawa products related to temperature control, you can check out the Yokogawa UT32A Temperature Controller. It offers advanced temperature control features and can be a great addition to your measurement and control setup.
Pressure and Flow Measurements
In pressure and flow systems, the peak hold function can capture sudden pressure surges or flow rate spikes. For example, in a hydraulic system, when a valve is suddenly opened or closed, there can be a significant pressure change. By using the UT52A with the peak hold function, you can record the maximum pressure value during these transient events. This is important for preventing damage to the hydraulic components and ensuring the proper operation of the system.
If you need sensors for your measurement applications, the Yokogawa PH8EFP Sensor is a high - quality option that can work in conjunction with the UT52A to provide accurate and reliable measurements.
Resetting the Peak Hold Value
After you have captured the peak value and completed your analysis, you may need to reset the peak hold value to start a new measurement. On the Yokogawa UT52A, this is also a simple operation. Look for the "Reset" button on the front panel. Press this button, and the peak hold value will be cleared, and the instrument will start capturing new peak values.
It's important to note that the reset operation should be done carefully, especially when you are in the middle of a long - term monitoring process. Make sure that you have recorded or analyzed the previous peak value before resetting it.
Advanced Tips for Using the Peak Hold Function
- Sampling Rate Consideration: The sampling rate of the UT52A affects how accurately it can capture peak values. In applications where the peaks are very short - lived, you may need to increase the sampling rate. Refer to the user manual of the UT52A to adjust the sampling rate according to your specific measurement requirements.
- Combining with Other Functions: The peak hold function can be combined with other functions of the UT52A, such as data logging. By enabling data logging while using the peak hold function, you can record a series of peak values over time. This is useful for long - term trend analysis and for detecting recurring peak events.
- Calibration: Regular calibration of the UT52A is essential to ensure the accuracy of the peak hold measurements. Follow the calibration procedures recommended by Yokogawa to maintain the reliability of the instrument.
If you are looking for a more advanced controller from Yokogawa, the Yokogawa Controller UT35A offers enhanced features and capabilities for more complex measurement and control tasks.
