14.4 Verification stamp/stamp position
The transmitter will operate like a standard transmitter as long as no verification stamp has been affixed
to it. This means that all settings that are allowable for customers are accessible, including on-site cali-
bration. Once the verification stamp has been affixed to the transmitter (closing a jumper in the electron-
ics compartment on the CPU printed board of the UMC3-30), no settings can be changed. After the verifi-
cation stamp has been affixed, the SG1 housing is screwed on and sealed with leads.
Stamp position
The UMC3-30 printed board in the electronics compartment (SG1 housing) contains a jumper that indi-
cates that the device is in Custody transfer mode. Once this jumper has been closed, no settings can be
changed and the CT operates in Custody transfer mode.

communication in Custody transfer mode
Measured values can be transmitted and parameters can be read without restriction when the device is in
Custody transfer mode. However, any attempt to change settings will be denied, which of course means
that counts cannot be changed either.
