ACOUSTIC

CONTROL

SYSTEMS

- 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.

NOTE:

THE INSTRUMENT READINGS MUST NOT DIFFER FROM THE TIME VAL-

UE SPECIFIED ON THE REFERENCE SAMPLE BY MORE THAN 2 µS EITHER
WAY! IF THEY DIFFER BY MORE THAN 2 µS, CONTACT THE MANUFACTURER.
