Proving interval of the gas measuring comples "ULTRAMAG" - 4 years. The volume, sequence and frequency of proving is determined by the proving document «Instruction. NMAS. Complexes for gas measuring "ULTRAMAG". SYAMI. 407229-671 MP. ».

The proving procedure can be downloaded from http://www.eposignal.ru/catalog/46.

During proving, the following operations should be performed:

1. External inspection.

2. Testing..

3. Determination of the error of pressure measuring channel.

4. Determination of the error of gas temperature measuring channel.

5. Determination of the error of correction factor.

6. Determination of the error of unconverted volume measuring channel.

7. Verification of the pulse value of output signal of unconverted volume measuringchannel.

8. Determination of the error of conversion of unconverted volume of the gas to standard conditions.

9.
Verification of invariance of the indications of complex in the absence of gas flowrate.
