01
Identify
Record the instrument
Capture the instrument details needed to distinguish the gauge and its calibration range before testing.
AccessRA Field Handbook · Android
Practical field tools for instrumentation and calibration work.
Use focused engineering calculations, follow a structured pressure-gauge calibration workflow and keep practical records from one mobile workspace.
Current availability
Distributed through Google Play testing. The pressure-gauge workflow and supporting field tools are being refined with technician feedback before production release.
Offline-oriented
Core tools and local records are designed for field use without continuous connectivity.
Technician-entered readings
Calibration readings remain under technician control; photos support documentation rather than measurement decisions.
Built through testing
Real technician feedback is shaping the workflow before production release.
Current test scope
Focused on work technicians actually repeat.
The test build intentionally stays narrow while the workflow is validated. New instrument modules are added only after the current experience is stable.
01
Calibration
Pressure-gauge workflow
Guide the calibration record from instrument identification through as-found and as-left readings while keeping the technician responsible for the actual indicated value and maintenance decision.
- Instrument identification and optional supporting photographs
- Flexible technician-entered pressure points
- As-found and as-left readings
- Result and record review
- Local calibration history
02
Field tools
Fast instrumentation calculations
Keep common signal calculations and worksheets close to the job without carrying a large engineering application into every field task.
- 4–20 mA scaling
- 3–15 psi scaling
- Five-point calibration worksheet
- Selected field unit conversions
- Broader calculations available through the AccessRA web Toolbox
03
Records
Keep the calibration context
Store practical calibration records so the readings, instrument details and result remain together instead of being rewritten across separate notes.
- Searchable local records
- Instrument details and calibration points
- As-found / as-left history
- Pass/fail record where applicable
- Delete and review controls
Designed around the job
Identify. Calibrate. Review. Keep the record.
The Field Handbook supports the technician's workflow; it does not replace the approved calibration procedure, reference standard or engineering judgement.
02
Calibrate
Enter actual readings
Apply the reference pressure using the applicable procedure and enter the observed gauge indication at each point.
03
Review
Retain the record
Review the as-found/as-left data and keep the completed calibration record available on the device.
Product direction
One stable workflow before the next instrument module.
The Field Handbook is being developed through real testing rather than a long list of unfinished modules. Pressure-gauge calibration is the current proving ground; additional instrument workflows will follow only when justified.
Field-first UICompact work surfaces and direct input instead of long explanatory screens.
Evidence without automatic measurementPhotos support identification and documentation; the technician remains responsible for calibration readings.
Local-first recordsCore calibration records remain useful even where connectivity is unreliable.
