Pump 2: Use the Deposit Weight After One Rotation to Determine the Correction Factor
1. Toggle the Volume screen to Pump 2 and enter the following variables for Pump 2:
• RPM 2 = 39
• Reverse % 2 = 0
• Dispense Volume (mL) 2 = 0.01
• Pump Size 2 = 0.01 mL
• Correction Factor 2 = 1
2. Disable Pump 1 (Main > Load > Disable Pump 1).
3. Make five (5) deposits of Part B, ensuring that a representative amount of fluid has dispensed each time.
4. Weigh the amount of all five deposits.
5. Divide the weight amount by 5.
6. Use the following formula to determine a Correction Factor:
Correction Factor
=
Desired amount
Amount dispensed
Example: If the target weight was 10.1 mg and the average weight of the 5 deposits was 9.8 mg, then:
Correction Factor
=
10.1 mg
9.8 mg
= 1.02
7. On the Volume screen, enter 1.02 for Correction Factor 2.
