- Checks levels of reagent tanks.
- Every hour, reads and records the turbidity meter readings in the daily log (PC 1 only). Cleans turbidity
meter once a day.
- Collects readings for the high and low set points on the pH and ORP. (PC 1 only. Rack Repair

On Saturday – pots are pumped and refilled. Once a shift – check that rectifier is set correctly, pots are working OK and pots are filled with chrome solution to correct level – add chrome solution as needed.
- Test PPM (parts per million) and pH on both nickel rinse (r-l) and the product from the NRU once per shift.
- Makes up or requests nickel reagents for testing.
- Visually checks the sprays on the chrome rinses and adjusts metering valve to keep rinses clean.
