OpenApp vs My LoopCal

Remote for your garage doors, front gate, tag to enter flat, keycard to enter office - those are all things you need to carry with you all day. Replace them all with one handy app. After downloading OpenApp and installing our custom device to your office/home installation, you can start controlling all those entry points from any place in the world. You can also share access with your family. You can give your friend access for 24 hours or surprise your business guests by giving them access to your office for a limited time.

LoopCal turns a 4–20 mA loop check into a calibration worksheet you can hand over, and it is the quickest way to convert a signal in the field. Built for instrumentation and calibration technicians. Fully offline. FROM CHECK TO WORKSHEET • Guided three-point, five-point, and custom 2–21-point checks • As-found and as-left runs, with the error and pass/fail at every point • Up-scale and down-scale readings with hysteresis • Tolerance as percent of span, signal units, or engineering units • Worst point and maximum error summarized for you • A clean PDF worksheet with your company name and logo, in US Letter or A4, plus CSV for your records CONVERT IN SECONDS • 4–20 mA, 0–20 mA, 0–10 V, 1–5 V, and your own custom signal endpoints • Direct-acting and reverse-acting ranges • Linear and square-root (flow) transfer functions • Engineering ranges with any unit, including negative and offset spans • Percent, signal, and engineering values update as you type, with the substituted formula shown • Verify this loop: take the range you just entered straight into a check EVERY INSTRUMENT ON RECORD • Save instruments with their ranges and calibration history • See what is coming due, and get a reminder before the next calibration • Reopen a saved instrument and start its next check without retyping the range LOOP POWER MATH • Shunt resistor voltage drop • Required supply voltage and remaining compliance • Maximum loop and wire resistance PRIVATE BY DESIGN • Everything runs on your device. No account, no ads, no tracking, no network. LoopCal is a calculation aid and field worksheet — not a calibrator, an accredited calibration service, or a replacement for manufacturer procedures. Always follow site lockout/tagout, operations authorization, device manuals, and approved procedures. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
