Ten test służy do badania wydajności pompy (pump output) poprzez pompowanie do "catch vessel," czyli do zbiornika (vessel) do zbierania cieczy (catch). Ponieważ on nie jest zbiornikiem głównym, on można też być nazwanym an auxiliary vessel, czyli zbiornikiem pomocniczym.

CATCH TEST
Prior to starting a chemical injection application, perform a catch test (if desired) to manually verify the pump output before operation. This test ensured the desired catch volume, volume caught, and flow correction are
correct. To perform a catch test:
1. Verify the catch vessel is large enough to catch the desired volume.
2. Ensure the end of the hose going from the pump to the catch vessel has a check valve to prevent excess fluid
from exhausting when the pump has stopped pumping.
3. Set the hand valve on the injection pump outlet to pump the fluid to the catch vessel.
4. Ensure the pump and hose are primed.
5. Verify the following conditions exist.
a. Injection pressure is less than 12 PSI [82.7 kPa].
b. Pump is off.

c. Vacuum pressure less than 11.5” of mercury [29 cm of mercury].
NOTE: The vacuum switch on the pump will engage and a flow alarm will display if the product cannot be
drawn into the tank (e.g. vacuum pressure at or above 11.5” or mercury [29 cm of mercury]). Check
screens, chemical tank lids, hose diameter and any hand valves between the chemical tank and pump
inlet. Also, verify the product if flowing freely. Cold temperatures and low viscosity products may
cause high inlet vacuum and cause the pump not to operate properly.
6. Press the Sidekick Pro ICD icon for the desired pump product number.
7. Select the Diagnostics icon.
8. Select the Test icon.
9. Select Catch Test from the drop-down.
10. Check the amount caught in the catch vessel after the catch test is completed. The caught volume should be
within +/-3% of the desired amount. If the caught volume is off by more than +/-3%, adjust the Flow
Correction percentage value. Increase the Flow Correction% by approximate error percentage to pump more
fluid if needed. Decrease the Flow Correction% to pump less fluid if needed.
NOTE: If the console displays an error message during the catch test, verify that the conditions listed in step 5 exist. If the problem persists, refer to “Troubleshooting” section on page 53 for troubleshooting information.
