microBrute DRSSTC Instruction Manual
h. Increase the handheld controller PW to increase the power levels of HV
output. You will need to increase the PW greater than 0 to see any output
arc.
POWER-DOWN Sequence
a. Decrease handheld controller PW to 0.
b. Unplug the Resonator Power AC power cord.
c. Unplug the Control Power AC power cord.
d. Wait 2 minutes before approaching the microBrute DRSSTC resonator
or PC board.
e. Before working on the PC board or making any adjustments to the
resonator, ensure there is no voltage on C43 or C44. Use a multimeter to
measure the voltage across both CR43, and CR44. Do not touch the PC
board until this voltage has decreased to 0 volts.
f. Allow fan to run for a few minutes to properly cool everything.
24. In this step, we will tune the primary coil of the Tesla Coil for maximum
output. Both PW and PRF settings on the handheld controller should never
exceed 50% during the tuning process. The tuning process is described as follows.
Repeat this process until maximum output arc is achieved.
TUNING PROCESS
The tuning process is very simple and only takes about 10-15 minutes to
complete. Once it is tuned, there is no need for additional tuning. The process
involves turning the microBrute DRSSTC ON and OFF and adjusting number of
primary turns. For this particular coil, it basically means adjusting from the initial
starting point of 3 turns to 2.9 turns, 2.8 turns, 2.7 turns, 3.1 turns, 3.2 turns, 3.3
turns, and so forth until maximum arc length is seen. This is illustrated in the
figure below:
a. Power-up microBrute DRSSTC (only power up for a few seconds)
b. Note the high voltage output of the coil and length of high voltage arc.
c. Power-down microBrute DRSSTC
d. If high voltage output is small, adjust the primary coil as shown below.
These adjustments should be made incrementally in both directions until
maximum output is achieved.
e. Repeat these steps until maximum output is achieved
