4.4 Sealing
1. Secure the housing cover
The housing cover is screwed on with four screws. Sealing occurs using adhesive la-
bels (
seal layout - see Chapter
4.6).
2. Closing and securing the calibration switch
Once all values subject to calibration regulations have been modified, the calibration
lock is closed by pressing the button (
"PROG" symbol goes out)
and the opening is
closed off with a capstan-headed screw. The calibration lock is sealed by a sealing wire
which joins the capstan-headed screw to the housing.
(See Chapter 4.6 for seal layout).
3. Securing the inputs
When used in applications subject to calibration for billing purposes, the required inputs
must be secured against tampering by calibration covering caps. Sealing is provided by
an adhesive label on the relevant covering cap.
(for seal layout see Chapter 4.6).
4. Closing the housing
Completely close the housing (battery compartment) and secure with four screws.
F
Make sure that no cables are pinched.
F
Ensure that the screws are securely tightened so that no moisture can pene-
trate the TC210.
4.5 Recalibration
When using the TC210 in applications subject to official calibration, the recalibration peri-
ods should be observed.
According to the
Calibration directive – General regulations
, issued in 2000, these re-
calibration periods are given in Appendix B under item number 7.10.
In the
PTB-Prüfregel, Band 20
(Standards Board Test Rules, Volume 20), the procedures
for testing electronic volume correctors for gas are described.
