HADS ingests the diagnostic database from ADASH DDS — the software that stores measurements captured with the ADASH VA5 instrument — and evaluates every measurement point against standards and your own limits, drafts a diagnostic conclusion with AI assistance and generates a customer-ready report in PDF and editable DOCX. No cloud, no package installation.

Customer data stays on the diagnostician's computer
Key features
HADS is not another spectrum viewer. It is a working environment where measured data becomes a decision — with standard-anchored limits, AI as an interpretation layer, and an output that can be sent to the customer without further editing.
Add, switch between, rename and delete multiple ADASH DDS databases in one place. Reading is optimised with indexes and batched trend loading, so even large databases remain usable for analytical work.
Measurement-point pages with static and dynamic data: an "all charts" view, cursors, waterfall spectra, speed detection, and bearing fault-frequency markers FTF, BSF, BPFO and BPFI shown directly in the spectrum.
A standards catalogue in the backend holds ISO 20816-3 limits, ČSN 20 0065 limits for milling-machine spindle bores and ISO 14694 fan limits. In addition, custom standards with classes and A/B, B/C and C/D thresholds — assignable to a whole machine or to individual bearings.
Machine-level and measurement-point assessment with model selection. The application sends a bounded context — latest measurement, trend, limits, bearings, running speed, standard — and the AI provides the interpretation. Conclusions can be edited manually and remain in history.
Recommended warning and alarm values are computed from the stored trend history using an exponentially weighted moving average. The proposal is always advisory only — you promote it into the manual limits with one button, and it never overrides the classification on its own.
A report editor with customer and order fields, per-machine conclusions, recommendations, selected charts and per-chart comments. The preview is generated the same way as the final PDF, so what you see is what you download.
Workflow
The workflow mirrors how a diagnostician actually works: data first, then limits, then interpretation, finally the document. Each step is independent, so you can go back without losing manual work.
Add the .ndb database created in ADASH DDS (which stores measurements from the ADASH VA5 instrument) to the library.
HADS reads the enterprise tree, machines and measurement points, including limits
stored in the database.
Fill in basic information, running speed and a machine image, and map bearings to measurement points. This activates FTF, BSF, BPFO and BPFI markers in the spectra.
Pick the standard and machine class, or a custom standard. Adaptive EWMA proposals from the trend history can be promoted into the manual warning and alarm limits.
Review spectra and trends, run a machine or point assessment, ask follow-up questions in the chat. The generated conclusion can be edited and saved — history is preserved.
Select the scope of machines in the editor, complete the cover page, pick trend and FFT charts, add per-chart comments and markers. Preview before download.
Download a PDF named after the order and customer, or export DOCX for peer review. Only conclusions and recommendations are re-imported — measurements stay untouched.
Sample output reports
The generated report starts with a management summary and an actions table. Detailed pages are produced only for problematic machines, and selected charts go into the appendix. Below are sample pages from all three report versions — the data shown is illustrative.

The subject of the measurement was 18 machines in the boiler-room and extraction systems. Measurements were taken with an ADASH VA5 instrument in operational state, evaluated according to ČSN ISO 20816-3, machine class per installation on a rigid foundation.
| Machine | Worst point | Value | Zone | Status | Recommended action |
|---|---|---|---|---|---|
| Extraction fan V-04 | VEN-2 envelope | 0.86 gE | D | Alarm | Schedule bearing replacement within 14 days |
| Extraction fan V-04 | VEN-1 horizontal | 3.15 mm/s | C | Warning | In-situ balancing of the impeller |
| Feedwater pump P-02 | PUM-1 vertical | 2.94 mm/s | C | Warning | Check alignment and foundation tightening |
| Compressor K-01 | KOM-2 horizontal | 1.92 mm/s | B | OK | Monitor in the next measurement cycle |
| Machine | Points | Max velocity | Max envelope | Zone | Trend |
|---|---|---|---|---|---|
| Extraction fan V-04 | 4 | 3.15 mm/s | 0.86 gE | D | worsening |
| Feedwater pump P-02 | 4 | 2.94 mm/s | 0.21 gE | C | stable |
| Compressor K-01 | 4 | 1.92 mm/s | 0.18 gE | B | stable |
| Combustion air fan V-01 | 4 | 1.14 mm/s | 0.09 gE | A | stable |
| Point | Direction | Velocity | Zone | Acceleration | Envelope | Zone |
|---|---|---|---|---|---|---|
| MOT-1 | H / V / A | 1.12 mm/s | A | 1.8 m/s² | 0.11 gE | A |
| MOT-2 | H / V / A | 1.86 mm/s | B | 2.4 m/s² | 0.14 gE | A |
| VEN-1 | H / V / A | 3.15 mm/s | C | 4.9 m/s² | 0.32 gE | B |
| VEN-2 | H / V / A | 2.71 mm/s | B | 9.6 m/s² | 0.86 gE | D |
1. Velocity severity per the standard. The highest RMS velocity of 3.15 mm/s was measured at fan bearing VEN-1 in the horizontal direction and falls into zone C per ČSN ISO 20816-3 — a state unsuitable for long-term continuous operation.
2. Velocity FFT and probable cause. The velocity spectrum is dominated by the 1× running-speed component at 24.6 Hz with an amplitude of 3.15 mm/s; the 2× and 3× harmonics are significantly lower. The spectral pattern matches an impeller imbalance, contributed to by a mildly increased compliance in the horizontal direction.
3. Acceleration and envelope assessment. At VEN-2 the acceleration envelope value of 0.86 gE is above the zone D threshold, and the 9.6 m/s² acceleration is also elevated. The envelope trend is rising over the last three measurements.
4. Acceleration FFT and envelope assessment. The envelope spectrum shows a series of harmonics of the outer-race fault frequency BPFO 88.4 Hz with sidebands spaced by the running frequency. The finding is consistent with developed outer-race damage of the bearing on the VEN-2 side.
Schedule replacement of the bearing at position VEN-2 within 14 days; during the outage perform in-situ balancing of the impeller and an alignment check. Until replacement, shorten the measurement interval to 14 days and track the acceleration envelope.
In-situ single-plane balancing of the impeller was performed with the ADASH VA5 instrument and evaluated per ČSN ISO 20816-3. A correction mass of 84 g was installed on the impeller rim at an angle of 137°.
| Point | Before | Zone | After | Zone | Improvement |
|---|---|---|---|---|---|
| VEN-1 horizontal | 3.15 mm/s | C | 0.84 mm/s | A | 73% |
| VEN-1 vertical | 2.28 mm/s | B | 0.71 mm/s | A | 69% |
| VEN-2 horizontal | 2.71 mm/s | B | 0.92 mm/s | A | 66% |
Velocity zone change. RMS velocity at the most loaded point dropped from 3.15 mm/s (zone C) to 0.84 mm/s (zone A), a 73% balancing success.
Velocity FFT after balancing. The 1× running-speed component fell to 0.58 mm/s; the spectrum shows no dominant component and no signs of looseness.
Acceleration and envelope. The envelope at VEN-2 remains at 0.81 gE — balancing did not affect it. The outer-race bearing damage finding stands.
Bearing status and operating recommendation. Replace bearing VEN-2 per the original recommendation within 14 days. After replacement, take a control measurement and verify that balancing remained in zone A.

Standards and deployment
Classification is driven by the standards catalogue in the application and limits from the ADASH DDS database. The application runs locally — the customer's database never leaves the machine.
| Zone | Meaning | Report status |
|---|---|---|
| A | New machines after commissioning | OK |
| B | Acceptable for long-term continuous operation | OK |
| C | Unsuitable for long-term operation, plan intervention | Warning |
| D | Risk of damage to the machine | Alarm |
