MasterRecipe: sim-ph-adjust-m1

pH adjustment test on sim-cell/mix-tank-1. Use this recipe to exercise the single-pass pH-adjust phase. The batch reads the tank pH, selectively doses acid or base based on deviation from target, and parks on an operator-verify prompt with the final pH and conductivity. Good for demonstrating SFC selective divergence with priority-ordered branches.

Where to find it

HMI endpoint → Batch Execution → + New → select sim-ph-adjust-m1.

What you see when it runs

Element	Meaning
Procedure	Running from batch start
Phase detail	ph-adjust diverges three ways — dose_acid, dose_base, or ph_in_range — depending on the initial pH vs target
Verify prompt	The phase parks on verify until the operator acknowledges the final pH reading

1	pressure-test	tank-pressure-test	Pressurize tank and verify no leaks
2	ph-adjust	tank-ph-adjust	Selective acid/base dosing with operator confirmation

How it works

1. pressure-test runs the standard tank leak check.
2. ph-adjust reads the simulated pH, evaluates safety limits, diverges to acid/base/no-op by priority, runs the dose, settles for 10 s, and parks on the verify prompt until the operator acknowledges, with the transition guarded by a four-way AND (ack non-empty, pH in tolerance on both sides, conductivity within limit).

Try it

1. HMI endpoint → Batch Execution → + New → sim-ph-adjust-m1 → Start
2. Click into ph-adjust and observe which branch fires based on the simulated initial pH
3. Respond to the verify prompt when the phase parks
4. Open Data endpoint → Trends on ph_sensor.PV and conductivity_sensor.PV to see the dose's effect
