B.2.3 As the average output signal of the moisture meter Vmg / use the arithmetic mean value
The GC of the moisture meter y is represented as
method and value of the moisture meter output signal.
B.2.2 A sample for PG1 calibration is placed in the cuvette from the moisture meter kit, the surface of the sample is leveled and, in accordance with
the OM, a single reading uPG1u is read from the electronic panel of the moisture meter. The operation is performed five times.
B.2.8 The calculated calibration coefficients are entered into the moisture meter memory in accordance with the OM.
GOST 8.613-2012
B.2.4 For PG2, PGZ repeat the steps in B.2.2-B.2.3. B.2.5 Simultaneously
with measurements with a moisture meter, determine the mass fraction of moisture in samples for calibrating PG1 - PGZ by the arbitration method
- Wnri, %. B.2.6 The initial data for the construction of the
GC moisture meter are the results of measurements of GHG by arbitration
