SERVICING/VERIFICATION

9.1 Information on servicing and verification
We recommend having your device serviced prior to verification.
NOTICE!
Incorrect measurements as a result of poor servicing
► Have servicing and repairs carried out exclusively by seca Service or by an authorized service partner.
► You can find service partners in your area at www.seca.com or by sending an e-mail to service@seca.com.
Have an authorized technician perform verification according to national legal regulations.
Verification is necessary whenever one or more verification seals are damaged or the contents of the verification counter no longer match the number on the applicable verification counter sticker. If verification seals are damaged, contact seca Service directly.
9.2 Checking the content of the verification counter
This seca scale is verified. Verifications may only be performed by authorized agencies. To guarantee this, the scale is equipped with a verification counter to record any change in verification-related data.
If you want to check whether the scale has been properly verified, proceed as follows:

1. If necessary, turn off the scale.

2. Press and hold any key and start the scale.
   The current content of the verification counter flashes in the display for a few seconds.

3. Compare the content of the verification counter output with the number given on the calibration counter sticker.

Both numbers have to match for the verification to be valid. If the sticker and the verification counter do not match, the scale must be verified. Please contact your service partner or seca Service. Once the scale has been verified, a new, updated verification counter sticker is used to identify the status of the verification counter. The person authorized to perform the verification secures this sticker with an additional seal. The verification counter sticker can be ordered from seca Service.
