(1) Set the CAPACITANCE RANGE switch (6) to the range which is compatible with
the value of tank unit capacitance to be simulated. For example, if it is desired to simulate
1900 pF, set the CAPACITANCE RANGE switch (6) to position 4000. Note that the best
digital display resolution and setting accuracy is obtained when setting the CAPACITANCE
RANGE switch (6) to the lowest range that will cover the value to be simulated. For the
example presented, setting the CAPACITANCE RANGE switch (6) to position 8000 would not
yield the best display resolution for simulating a tank unit capacitance of 1900 pF.
(2) Once the suitable CAPACITANCE RANGE switch (6) position is selected, the
PROBE-SIMULATOR switches (22, 23) and fine adjustment control (24) must be set to the
desired value of simulated tank unit capacitance. For example, to simulate 1900 pF, set
the 1000 pF increment switch (22) to position 1000, set the 200 pF increment switch (23) to
position 800 and then rotate the 15-390 pF fine adjustment control (24) for a display (7) reading
of 1900.
b. To set the simulated compensator capacitance (with the equipment set up as shown
in figure 2-2), position Test Set switches as follows:
