Clean the balance and try again

• B.

• C.

• D.

Do nothing

A. Clean the balance and try again
Explanation
You may also let your supervisor know, but you should try to assess the situation first.

Try again, third times a charm

• B.

• C.

Place a do not use label on the balance

• D.

Do nothing

C. Place a do not use label on the balance
Explanation
If you have cleaned the balance and the weights are still not within range, it is time to take further action. Inform your supervisor and do not use the balance for testing materials until you can determine if there is an error with the balance or the weights.

### During calibration,  if  a piece of equipment fails calibration is a deviation invesitgation needed?

• A.

Yes

• B.

No

A. Yes
Explanation
The impact to the quality of the product needs to be assessed if the product was testing with a piece of equiment that was not within calibration.

• C.

Do nothing and go home

B. Inform the production supervisor

### All instruments must have a calibration due date sticker on them.

• A.

True

• B.

False

A. True
Explanation
All instruments must have a calibration due date sticker on them to ensure that they are regularly calibrated and maintained for accurate measurements. This sticker serves as a reminder for when the instrument needs to be recalibrated, helping to maintain the instrument's reliability and accuracy. It also helps in tracking the calibration history of the instrument, ensuring that it is within acceptable limits and meets the required standards.

### While writing up your data from an HPLC run, you discover that the HPLC is beyond its calibration data.  You should (check all that apply)

• A.

Do nothing, maybe the verifier wont notice

• B.

Explanation
It is important to inform your supervisor when you discover that the HPLC is beyond its calibration data. This is because using an instrument that is not properly calibrated can lead to inaccurate results and compromise the integrity of the data. By informing your supervisor, they can take appropriate action to ensure that the HPLC is recalibrated or replaced, if necessary, to maintain the accuracy and reliability of the analytical results.

• 7.

### You can use data obtained from an instrument that is beyond its calibration date.

• A.

True

• B.

False

B. False
Explanation
Data should be obtained from instruments that are within their calibration period. If you have tested material using an instrument that is beyond its calibration date and it has been caught before being reported to production, the results should be voided and the material retested once the instrument has been calibrated. If the error was caught after the results had been reported to production, the impact of using an instrument beyond its calibration data would need to be assess through a deviation investigation.

Rate this question:

• 8.

### Service protocols wirtten by an outside contractor should be approved by CSP prior to using to calibrate or maintain and instrument.

• A.
