Check all segments for clarity and contrast. Clamp meter Position- it should be flat and in the middle 11. These 2 are somewhat related, having a knowledge in calibrating a multimeter will give you a good idea on how also to calibrate a clamp meter because clamp meter nowadays is also equipped with the capability of a multimeter. But nowadays, the capability of a clamp meter is almost the same with a digital multimeter where it can also measure resistance, voltage, and frequency which is basic to a multimeter. Referring to Table 2 for the 321 and Table 3 for the 322, put the Meter in the desired function and range for each test. To replace the batteries refer to Figure 1 : 1.
Prima di usare questo strumento, leggere il documento 321, 322 Clamp Meter Safety Sheet. How to use it properly during calibration or maintenance? Clean the Clamp meter with a soft cloth, Check if it has good batteries, replace low powered batteries. Determine the parameters and test points to be calibrated on the Clamp meter, choose at least 5 test point. Verification is almost the same with the multimeter in most parameters. Lees het 321, 322 Clamp Meter Safety Sheet voordat u deze meter gebruikt Les 321, 322 Clamp Meter Safety Sheet før måleinstrumentet tas i bruk. A clamp meter is specifically designed to measure currents in a current carrying conductor or cable, also called a clamp-on ammeter see.
Lift off the top case. Model 333 is not equipped with this feature. But it is also applicable to most clamp meters with other manufacturers. Calibration Method: This is accomplished by comparing the electrical signal generated by Fluke 5522A, which is the reference standard. Adjustment is based on the skill and knowledge of the technician and it is a plus if you have it.
How to Calibrate a Clamp Meter? Each button push will cause the meter to beep. Remove the screws on the bottom of the Meter. So we will also expect to calibrate the Voltage, Resistance and Frequency functions. So how it is being used can now be compared to a multimeter when it comes to industry troubleshooting and monitoring. The procedure is based on the manufacturer manual so anyone can use directly the limits or tolerance presented.
If the readings are already within limits update the corresponding record, do labeling and sealing and issue to the owner, otherwise, do necessary repair or adjustments. Parts, product repairs, and services are warranted for 90 days. Discontinue calibration if any defect is noted. Where Do We Usually Use a Clamp Meter? We will just compare the reading from a standard source which is the calibrator also known as the reference standard to determine how far its reading was from its true value. Lift off the top case.
How to review and interpret the content of a calibration certificate? The coil is used to amplify the current needed by the clamp meter. You may visit this link to see how a is calibrated. Check the link below Visit here: What if you do not have a standard coil? Lisez la fiche de sécurité 321, 322 Clamp Meter Safety Sheet avant d'utiliser cet appareil. What is a Clamp Meter? Lue 321, 322 Clamp Meter Safety Sheet ennen tämän laitteen käyttöä. Set up for Voltage, Resistance, and Frequency Verification 7. Just like calibrating a multimeter, the connections and procedure are the same in terms of connections and key functions of the Fluke 5522A. The 32X Calibration Information provides the information necessary to verify the performance and adjust the calibration of the Fluke 321 and 322 ClampMeters, hereafter known as the Meter s.
Clamp the clamp meter on the coil, make sure it is positioned straight or flat at the middle of the coil for better accuracy. It has also an advantage of safety and there are no interruptions of work because you do not need to cut or open a wire. Allow a stabilization of 1 hour, to be conditioned on the environmental conditions of the room. Do you need a guide on what to include in a calibration certificate? Remove the screws on the bottom of the Meter. A simple demonstration on how a clamp meter is calibrated using a multiproduct calibrator Fluke 5522A To learn more about the calibration procedure, visit this link.
Objective: To define the verification procedure on digital clamp meters using Fluke 5522A Multi-product Calibrator As the reference standard with Fluke 5500A coil as an accessory. A clamp meter is used in a wide range of high current measurements without opening or cutting the wire. Fluke 321 Performance Verification Test Limits , For the list of Clamp meters, please click this link. Each button push will cause the Meter to beep. We have already seen how a is being calibrated or verified using a multiproduct calibrator and now, we will see how a clamp meter will also be calibrated. End of Verification Conclusion I have presented here the calibration procedure of a clamp meter using the reference standard Fluke 5522A and a coil. Fluke 322 Performance Verification Test Limits Table 1.
And the best thing is that you do not need to open the cable or cut into it just to measure the current. . Disconnect the test leads before replacing the batteries. . . . .
