Calibration Pump Window

Follow the instructions displayed. Use the red dotted line and/or the blue timer arrow as a

target flow rate. Try to inject the air from the syringe at a rate close to that of the red line.

Remember that the syringe handle attached to the plunger must be pulled all the way out

before you inject. Once the handle is all the way out, inject the air from the syringe until

the handle is all the way in. PUSH THE HANDLE IN AND DRAW THE HANDLE OUT

SMOOTHLY – TRY NOT TO “BANG” THE PLUNGER AS YOU PERFORM THE

MANEUVER. “Banging” the plunger can cause the timer arrow to start to count. If it

does, just wait for the timer to reset and inject the plunger. This will not affect the

calibration results.

If the pump is performed correctly, the program will prompt you to begin a second

injection. Repeat the process, injecting all of the air in the syringe. If the injection is not

performed correctly, the system will discard the attempt and prompt you to inject again.

After three correctly performed injections, the system will automatically calculate a

correction factor and prompt you to perform a verification pump. ALWAYS VERIFY

YOUR CALIBRATION. After a verification injection, the software will display the

measured volume and the percentage difference from 3.0 Liters. The ATS recommends

that the verified volume should be between 2.91 and 3.09 (+/- 3.0 %) to be accepted. Be

sure to check these numbers before accepting the verification.

The verification acceptance dialog box will display those numbers for quick and easy

comparison. Click Yes if the verification flow is within the recommended parameters. If

the flow is not within the parameters, click No and repeat the verification flow.

Verification Acceptance Dialog Box

After you accept the verification, the system automatically saves the calibration. To print

the calibration report, click Print and select PRINT from the menu. To view the

calibration report, click Print and select PRINT PREVIEW from the menu.
