# Mandel pressure readings and Alarms page — October 24, 2026
## Live review follow-up — October 24, 2026
User reported variables working and requested assessment. Read-only review confirmed Well pressure readouts and three-series history now populate. Observed snapshots: tank 49.4–50.1 psi, well about 50.6 psi, differential 0.6–1.2 psi; consistent with well minus tank within display rounding/asynchronous updates. Pump Off, flow 0.0 gpm, water level 54.6 ft. This idle snapshot does not establish filter restriction under flow or physical sensor calibration.
Pressure Alarms page still shows -.- for all numeric settings/states. Native register table independently showed blank tank limit input/output values despite Enabled Yes; tank output g_tankPres_out_eu returned 49.55425262451172. No page console errors observed. Active alarm modal lists High and High-High for Tank, Well and Filter Differential (six records), each timestamp 2026-10-24 17:44:22. Cause, current threshold values and why limit source values are not readable remain unverified; do not assume normal or default-zero thresholds. No acknowledgment/reset or configuration/PLC writes performed.
Assessment: primary tank display works and trends render. Suggest a separate differential chart scale to reveal small changes near 1 psi alongside absolute pressures near 50 psi; suggestion only, not applied. Highest priority is restoring readable alarm settings/states and checking threshold appropriateness before claiming alarm commissioning complete.
Completed configuration on https://dev.atomhmi.com/site_mandel/ after the user corrected the imported PLC register file. Main catalog now shows 1,431 entries. Earlier missing-tag checks and wrong 3,393-register import are historical; see MANDEL-PRESSURE-AUDIT.md.
