The method
Before using the result
- This is a local worksheet. Findings and supplied criteria remain the responsibility of the person recording them; the output is not a certificate or regulatory approval.
- Do not compare different meter scales as if they were equivalent physical moisture content.

1. Worked example
Build a repeatable job log that preserves material, meter mode and measurement location. Use comparable trends and environmental readings rather than treating every meter number as percent moisture.
Supplied drying measurements
| Measurement date | Location | Material | Instrument ID | Mode / measurement method | Reading on stated scale | Instrument reading unit | Air temperature (°C) | Air RH (%) |
|---|---|---|---|---|---|---|---|---|
| 2026-10-01 | Wall A | Wood | Meter A | Wood scale | 24 | Instrument units | 25 | 70 |
| 2026-10-03 | Wall A | Wood | Meter A | Wood scale | 18 | Instrument units | 25 | 50 |
- Group readings by location, material, instrument, mode and unit.
- Compare trends only within the same series. An instrument scale is not automatically a moisture percentage.
- Readings recorded: 2
- Like-for-like series: 1
No drying target, microbial conclusion or cleaning threshold is inferred from these readings.
2. Comparison example
Compare a different supplied condition using the same method. For Restoration Cert Lab, the important check is that the input meaning, units and method assumptions still match the problem.
Supplied drying measurements
| Measurement date | Location | Material | Instrument ID | Mode / measurement method | Reading on stated scale | Instrument reading unit | Air temperature (°C) | Air RH (%) |
|---|---|---|---|---|---|---|---|---|
| 2026-10-01 | Wall A | Wood | Meter A | Wood scale | 30 | Instrument units | 26 | 60 |
| 2026-10-03 | Wall A | Wood | Meter A | Wood scale | 22 | Instrument units | 26 | 60 |
- Group readings by location, material, instrument, mode and unit.
- Compare trends only within the same series. An instrument scale is not automatically a moisture percentage.
- Readings recorded: 2
- Like-for-like series: 1
No drying target, microbial conclusion or cleaning threshold is inferred from these readings.
Check your understanding
1. Which relationship is used?
Date-order measurements, preserve instrument/mode/material identity, and plot each comparable series separately.
2. Which assumption should you check first?
This is a local worksheet. Findings and supplied criteria remain the responsibility of the person recording them; the output is not a certificate or regulatory approval.
3. How should you verify a different unit system?
Convert every input to the displayed calculation units first. Equivalent physical inputs must give equivalent results; a unit label alone does not convert a number.
