The Calibrate Flowmeter - Catch test allows the operator to catch product and enter the exact amount caught to calibrate the flowmeter.

Catch Test Description (B) - Adjusts the calibration valve by dispensing product into a container without moving the machine and entering amount collected.

Place containers (such as calibration container) under up to 7 nozzles to capture volumes sprayed during the test. Only 7 samples may be entered into the sample volumes popup screen. Calibrating Flowmeter may be repeated as many times as needed if all nozzles are to be tested. By measuring these samples and entering the values into the system, an accurate flowmeter calibration value can be attained. Follow the on-screen instructions as described.

1. Configure the control valve and flowmeter in Setup (Softkey G).

2. Select Calibrate Flowmeter - Catch from the Tests drop-down menu.

3. Be sure the flowmeter is clean.
