7. Select the position of SW1 corresponding to the highest reading and note
that reading.
8. Using a screwdriver, rotate TC1 through 360
0
and note the action of the
loop meter. If when rotating TC1 through one complete revolution, the loop
meter does not raise above the reading obtained at stage 6, rotate SW1
one position anti-clockwise and again continue from step 8.
9. When rotating TC1 through one complete revolution the loop meter should
show 2 positions when the meter is at its highest.
10. Rotate TC1 to obtain the highest reading on the loop meter.
The next operation is carried out to adjust the loop output meter to read 8.
This is to provide a datum reading for any future evaluation of transmitter
performance.
Note!
It should be understood that although the reading of the loop output meter is
being adjusted during this operation, the actual output of the transmitter and
the loop tuning is not being affected in any way. The only thing that is being
changed is the coupling of the output meter to the transmitter.
It is important that this is understood and that this operation is only carried out
during installation or replacement/re-siting of the loop. The core of LC1 is
made of carbon. It is very brittle so adjust it with care.
1. Locate LC1 (See Diagram 2.12).
2. Using a small screwdriver carefully rotate LC1 to adjust the loop meter to
give a reading of 8.
2.13 The Master Timer
The master timer (Diagram 2.09) is mounted on the transmitter motherboard.
It produces a constant stream of pulses whilst the unit is turned on. The gap
between the pulses is controlled by the knob mounted on the front of the unit.
The slave timer (mounted in each console) counts a fixed number of pulses to
determine when to end the game. By varying the gap between pulses the time
taken to send (and therefore count) a given number of pulses also varies. In
this way the length of the game is altered. Rotating the knob fully anti-
clockwise sets the shortest time and clockwise the longest. Changing the
setting during play will lead to a proportional change in that (or those) games.
The pulses are distributed to the slave timers via the console connection
cables. If the pulses should not be sent (or not arrive) the slave timer will not
end the game.
