Structural and basic schemes of device cable are given in the appendix F.
After meter commissioning and also in cases of repairs, verification and adjustments,
service worker should record corresponding information in Table 19.
CAUTION! IT IS FORBIDDEN:
1 To break the procedure of cable connection according to marking in tables 9.4 – 9.6.
2 To swap RTD of temperature sensors

3 To increase or shorten the length of cables of ultrasonic flow sensors FlS.
4 To apply FS, RTD, ultrasonic flow sensors FlS and calculators from different deli-
very sets.
5 Cable twisting, kinking and sharp bends is not permitted while connecting to FlS.
CAUTION!!!
If it was required to make welding during device commissioning, the meter should
be switched off and device cable should be disconnected from the calculator housing.
Otherwise the meter can be damaged.
10 Setting-up Procedures
10.1 While meters work with additional devices (PC), these devices should be connected
to meters strictly according to maintenance documentation.
10.2 For comfortable work with the meter (after its purchase and before installation) and
for check of meter working capacity together with ultrasonic flow sensors it is necessary:
1) Assemble a flow meter section with rubber or paronite gasket (thickness of 1-2
mm) and technological cap at the end face, install it vertically, fix flow sensors, and
completely fill FS with water.
2) Check up all items in «Indication of main parameters» mode, check up all items
in "Check" mode and also it is obligatory to provide zero setting in "Setup" mode to
