SOP 18/19 Calibration of Open Neck Field Standard Test Measures

The video tutorial explains the calibration of a handheld field standard test measure using a slicker plate standard. It covers the wetdown process, followed by a detailed nine-step calibration procedure. The tutorial emphasizes the importance of accuracy and avoiding measurement errors. It concludes with notes on discrepancies and future topics.

What is another name for the slicker plate standard?

• Calibration plate

• Measurement plate

• Standard plate

• Slicker

Why is the wetdown process important before calibration?

• To test the equipment's durability

• To record initial data

• To ensure all specified pour and rain times are observed

• To clean the equipment

What is the first step in the nine-step calibration procedure?

• Measure the temperature

• Fill the slicker plate standard

• Record the scale reading

• Empty the test measure

How should the fill tube be positioned to minimize air bubbles?

• Outside the standard

• At the top of the standard

• In the middle of the standard

• To the bottom of the standard

What should be done if air is trapped under the slicker plate?

• Ignore it

• Continue with the process

• Add more water

• Remove the plate and try again

What is the specified angle for holding handheld test measures during the final drain?

• 10 to 15 degrees

• 15 to 20 degrees

• 20 to 25 degrees

• 5 to 10 degrees

What is the purpose of placing a card with a black and white half during the meniscus reading?

• To measure the temperature

• To stabilize the test measure

• To properly indicate the bottom of the meniscus

• To clean the test measure

What should be done if the temperature difference between the slicker plate standard and the test measure exceeds the specified limit?

• Ignore the difference

• Perform calculations of Aesopi 19 or discard the data

• Continue with the next step

• Adjust the temperature manually

What should be checked if there is more than 0.2 cubic inch disagreement between scale readings for runs one and two?

• The timing of the process

• The calibration process

• The cleanliness and condition of the vessels

• The temperature of the water

What future topics are mentioned to be addressed in upcoming videos or podcasts?

• New measurement standards

• Advanced calibration techniques

• International calibration guidelines

• Adjustment and sealing of the test measure for legal metrology use
