- Switch On the instrument.
- Select TIME as an observed value.
- Place the instrument on the reference sample as indicated in the Figure 12.
- Apply pressure on the instrument and fix it.
- Wait for 15 20 seconds for the readings to become stable.
- Read and record at least 5 measurement readings.
- Remove the instrument from the sample.
- Calculate average time value according to the received data.
- Measure actual temperature of the reference sample.
- Find the difference between the 20°С and actual temperatures.
- If actual temperature is different from 20°C, then subtract the temperature difference value, multiplied by 0.07 µs, from
the calculated average time value.
- Compare the result with the time values specified on the sample.
