Flir Extech PRC20 Calibrator F.A.Q.

How do I perform a basic voltage calibration using the Flir Extech PRC20?

To perform a basic voltage calibration, connect the device under test to the PRC20's output terminals. Select the voltage function on the calibrator, set the desired output voltage, and adjust the device under test until its reading matches the PRC20's output.

What should I do if the PRC20 displays an error message during calibration?

If an error message is displayed, first check all connections and ensure they are secure. Verify that the selected range and function are correct for your application. If the issue persists, consult the user manual for specific error codes and troubleshooting steps.

How often should the PRC20 be calibrated for best accuracy?

It is recommended to calibrate the PRC20 annually or as per your organization’s quality assurance program. Frequent usage or harsh environments may necessitate more frequent calibration.

What maintenance is required for the PRC20 to ensure long-term reliability?

Regularly inspect the PRC20 for physical damage, clean the connectors with a dry cloth, and store it in a dry, dust-free environment. Replace batteries as needed and keep the device away from extreme temperatures.

Can the PRC20 be used to calibrate thermocouples?

Yes, the PRC20 can simulate thermocouple signals for calibration purposes. Select the appropriate thermocouple type on the calibrator, and connect the thermocouple leads to the PRC20. Adjust the output to match the desired calibration point.

What steps should I take if the PRC20 does not power on?

Check the battery compartment to ensure the batteries are correctly installed and have sufficient charge. Replace the batteries if necessary. If using an AC adapter, verify that it is connected properly and functional.

How can I ensure accurate readings when using the PRC20?

Ensure all connections are clean and secure, use the correct function and range settings, and allow the PRC20 to stabilize at the calibration point before taking a reading. Regular calibration of the device itself will also ensure accuracy.

Is it possible to use the PRC20 for current loop calibration?

Yes, the PRC20 can source and measure current for loop calibration. Select the current function, connect the PRC20 in series with the current loop, and set the desired current output for calibration.

What to do if the PRC20 readings are consistently incorrect?

Verify that the PRC20 is calibrated and functioning within its specifications. Check for any external sources of interference, such as electromagnetic fields, and ensure the device under test is also functioning correctly.

How do I update the firmware on the Flir Extech PRC20?

Refer to the manufacturer's website for the latest firmware updates. Follow the provided instructions, which typically involve connecting the PRC20 to a computer via USB and using specialized software to perform the update.
