CONTROLS & SETTINGS
VOLTS
The amplitude of the PES
®
output can be
varied between 20 and 400 volts, in 5 volt
increments. After pressing VOLTS, use the
and
buttons to scroll through the
available voltages. Press SELECT to load
the voltage setting into memory.
FREQ
Multiple options available are for the
frequency of the pulsed DC output by
the PES
®
. Pulse frequency can be varied
between 5 Hz and 100 Hz, in increments of
5 Hz, and then 250Hz, 500Hz and 1000Hz.
After pressing FREQ, use the
and
buttons to scroll through the frequency
options. Press SELECT to load the desired
frequency setting into memory.
When the Pulse-Type is Burst-of-Pulses
the Burst Frequency (inner frequency)
is displayed first followed by the Cycle
(outer) Frequency. Each frequency must be
selected individually by using the
and
buttons.
When the Pulse-Type is Standard Pulse,
only the Cycle Frequency is displayed.
When the Pulse-Type setting is Ramped-
DC, the message “Not used in DC” is briefly
displayed, the screen then returns to the
previous menu.
DUTY CYCLE
Pressing DUTY CYCLE displays the
calculated “percentage of time” for the
selected pulse type and frequency.
When the Pulse-Type is Standard Pulse, the
calculated on-time (the ratio of the length
of the pulse to the period of the waveform)
is displayed. Options for duty cycle vary
between 1 and 99%. After pressing DUTY
CYCLE, use the UP (
) and DOWN (
) to
scroll through the available options. Press
SELECT to load the desired setting into
memory.
When the Pulse-Type is Burst-of-Pulse,
the duty cycle of the two frequencies is
displayed. The duty cycle of the inner burst
is displayed first, followed by the frequency
of the outer cycle and the duty cycle of the
CYCLE frequency is displayed second.
When the Pulse-Type is Ramped-DC the
message “Not used in DC” is displayed.
TIMER
Termination of the output of the PES
®
can
be automated with the TIMER or controlled
manually. The TIMER can be adjusted from
1 to 255 seconds or “disabled”.
The output of the PES
®
is always controlled
by the hand switch.
When PULSE TYPE is STANDARD PULSES
or GATED BURST the minimum time for
output is 1 second and the maximum is 255
seconds.
When PULSE TYPE is Ramped-DC the
minimum time is 2 seconds and the
maximum time is 256 seconds: One second
is needed to ramp up the voltage and one
second to ramp it back down.
DUAL MODE
The PES
®
can be configured to output
two different doses, in sequence. In
this configuration, a secondary dose is
delivered following a primary dose, when
the primary waveform TIMER elapses on
a single activation of the remote switch.
Each of the phases of the exposure the
primary phase and the secondary phase
are programmed by the user using the
PULSE TYPE, DUTY CYCLE, FREQ,
