Calculator Pro
Formulas inside test templates
Let a template do the arithmetic: a spread across cells, a difference between two pins, an average over a channel range. Creating and editing calculations is part of Pro; Pro is an in-app upgrade, see Pricing.
iOS and Android, beta this winter.

Derived steps
A derived step computes when all its inputs have values. It recomputes when an input is redone. The result is checked against the step's limits like a reading, and exported as a row marked as calculated. For limits, see Pass/fail limits.
Examples that work:
step("Pin14") − step("Pin13")step("V") × step("I")(live − nominal("Rail 3V3")) / nominal("Rail 3V3") × 100avg(ch("Pins 16–40", 1..25))

Summary calculations
A template-level summary calculation, such as "Avg Ω ch 16–40" or "Max deviation", is computed at finish and printed in the report summary.
Starter templates with derived steps
The cell-voltage spread in starter template 4 and the winding imbalance in starter template 6 are examples. To build your own, see the Template builder.
Imported templates and trial runs
Calculations in a template are always evaluated when it runs, including trial runs and imported templates. Only creating or editing them needs Pro.
What it does and doesn't do (yet)
| What it does | Plan |
|---|---|
| Formulas inside templates: derived steps and summary values, computed in the run. | Pro |
Pro is an in-app upgrade. See what is Free and what is Pro.
Not yet, or not planned
- Formulas reference the current run only; no cross-run analytics.
Questions
Do imported templates still compute without Pro?
Yes. Calculations in a template are always evaluated when it runs, including trial runs and imported templates. Only creating or editing them needs Pro.
Can a formula use another run?
No. Formulas reference the current run only.
