8.6. When the primary converters are connected and endured in switched up position during
20 minutes RMT is ready for work.
8.7. Maintenance service
8.7.1. Replacement of plotting paper
1.. 2 м before ending of the tape of plotting paper there is an inclined red strip appearing on it.
Put forward the tape drive mechanism according to article 8.1 and take the accepting spool off
by pulling it downwards. The spool left end face is pulled down, and the roll is kept on the
remaining part of the spool.
The paper is released and can be removed by the reeled - up plotting paper rotation in the
direction opposite the reeled – up one.
Insert the empty accepting spool into the initial position.
It is necessary to remove the dust from the tape drive mechanism when replacing the plotting
paper.
8.7.2. Make replacement of recording device when the RMT is switched off and the tape
drive mechanism is taken out, according to article 8.2.
The functional switch should be installed in position "Р" (replacement of the recording
device), in which the linear electric motors on right emphasis stop working. Put the top scale
forward with the help of a handle and take out the recording device for the third measuring channel.
Remove the recording devices of the second and first measuring channels in the same way. Insert
the new recording devices in reversed way, establishing simultaneously the appropriate scales into
the initial position.
