9.1 Instrument verification
The SITRANS SL should be verified within the time interval stated in the Technical data
(Page 181). This procedure can be done by the custo
mer or the Siemens Service.
The verification of the instrument shall only be performed with the appropriate verification kit
(see accessory list in section "Accessories (Page 193)").
Each verifi
cation process should be documented. For this purpose there are verification
sheets included in Verification Sheets (Page 198) of this operating instructions.
If the v
erification fails, contact Siemens support.
Note
The verification kit is not part of the standard delivery. If you carry out the verification
yourself, you have to order the verification kit additionally.
The zero value (the reading when there is no measurement gas in the measurement path) is
compensated by the signal processing algorithm.
Note
It is not necessary to verify the zero value in field.
