MICROCURRENT - Treatment Instructions
46
Audio Tone
The audio tone allows monitoring of conductivity throughout the microcurrent treatment to
ensure adequate contact between the patient’s skin and the probe or electrodes for purposes of
patient safety and comfort. The unit senses conductivity of the connection as soon as current
is applied, and continues throughout the treatment.
Microcurrent Default Settings
The following default settings are set by the manufacturer and are selected when you press
Micro. You may change these defaults to your own preferred settings. See “Setting
Defaults” in this manual.
The Microcurrent treatment setup with electrodes is the default, and the following defaults are
also selected:
• Bipolar wave
• .3 Hz frequency
• 50 µA intensity
• Time: 20 minutes, counts down
• Audible Tone: Off
If Probe treatment is selected, the following defaults are automatically selected:
• Negative unipolar wave
• 4 Hz frequency
• 300 µA intensity
• Time: zero, counts up
• Audible Tone: On
Available Ranges:
• Frequency: Between .1 and 500 Hz
• Intensity: Between 10 and 990 microamps (in increments of 10µA).
The ranges of .1 to 500 Hz frequency and between 10 and 990 micro amperes intensity are
available for setting up both electrodes and probes treatments. For guidance in selecting the
appropriate frequency and intensity for a given probes or electrodes treatment, consult
published medical literature.
How To Use Microcurrent Probes
(The microcurrent active and ground probes are optional accessories available from
Dynatronics) For both the active and ground probe, use the end of a cotton swab (such as a
Q-Tip
®
) inserted into the end of the probe. Cut the end of the swab to a short length. The
cotton must touch the metal ring at the tip of the probe. Use a conductive electrolyte spray or
water to wet the cotton swab before treating. If the cotton dries out during treatment,
conductance may become erratic. Rewet the cotton, if needed.
Active Probe: To deliver the current to the patient through the active probe, first set up the
probe treatment and press Start. Then hold the probe as you would hold a pencil, and press
the button near the tip of the probe to start delivery of current. The active probe should touch
the patient’s skin at the treatment site, and the ground probe should touch the patient’s skin
elsewhere near the treatment site. This completes the circuit and delivers current to the
