Equipment Calibration Management

ECOSIRE builds a proper Frappe application (ecosire_calibration) with its own module and DocTypes rather than bolting fields onto core. The centerpiece is an Instrument (or Calibration Equipment) DocType holding the asset link, calibration interval, tolerance limits, standard/reference traceability, and a computed next_due_date. A Calibration Event DocType captures each calibration: performing vendor, reference standard used, as-found and as-left readings per measurement point, pass/fail verdict, and the certificate file. A hooks.py scheduler event runs daily to recompute due dates, flag instruments crossing into an overdue window, and enqueue reminder notifications to the responsible metrology role. doc_events on the Calibration Event recalculate the parent instrument's status on submit, and a server-side validation blocks submission when as-left readings fall outside the configured tolerance without a documented disposition.

Out-of-tolerance and overdue instruments are made unmissable and, where you need it, enforceable. We add status flags and dashboard indicators, and — for shops that require it — a validate hook on the consuming document (for example a Quality Inspection or Work Order operation) that refuses to reference a gauge whose calibration_status is Overdue or Out of Tolerance, with the block reason surfaced to the operator. Certificates are stored as native Frappe File attachments with version history, and whitelisted REST methods (@frappe.whitelist()) expose calibration status and upcoming-due queries so external MES, LIMS, or Power BI tools can read state over the Frappe REST API. Role profiles and permission rules scope who can register instruments, record calibrations, and override a lockout, with every override written to the audit trail.

Because this is build-to-order, nothing ships as a one-click marketplace download. After a short scoping call we confirm your instrument taxonomy, tolerance and interval rules, certificate template, lockout enforcement points, and target version (ERPNext v15 or v16). We build against a staging bench, run UAT with your metrology team, then install on your instance with a documented rollback plan. Typical delivery is 2-4 weeks from confirmed scope. You receive the full source repository, so the app is yours to keep, extend, and maintain.
