MODE

Interpretations

Burst

(B)

The burst mode provides a “burst” of seven pulses. There are two bursts that are delivered per second. Positive pulse and negative pulse iterate continuously at fixed 100Hz. Pulse width are adjustable from 50~300μs

Normal

(N)

The normal mode produces a continuous train of impulses. The stimulation parameters are not automatically interrupted nor varied in any way. In this mode, the pulse rate (from 2 to 150Hz) and pulse width (from 50 to 300μs) are fully adjustable. The normal mode is quite versatile because it may be applied with a variety if rate and width settings.

Modulated Rate & Width

(MRW)

The pulse rate and width are automatically varied in a cycle to produce a pleasant, massage-like sensation. It’s believed that nerves can become accustomed to, or “accommodated” to the same electrical stimulus after a period of time and thus would require increasing the intensity to further “block” the pain. The MRW mode was produced to offer a variety of different electrical stimulation, thus preventing nerve accommodation so that less intensity is required for long and effective treatment.  In this mode, during the beginning of 0.5 second period, the WIDTH decreased to 50% of its original setting and then during the next 0.5 second period, the RATE is decreased to 50% of its original setting. Therefore, the total cycle time is 1 second.

Strength

Duration

(SD)

Strength-Duration modulation consists of alternating modulated intensity and pulse width, so that the intensity is always increasing while the pulse width is decreasing and vice-versa. The stimulation intensity is modulated to 62.5% maximum of setting (width equal to setting). The pulse width is modulated to 67% of setting (intensity equal to setting). Total cycle time is 6 seconds.  Pulse rate (from 2 to 150Hz) and pulse width (from 50 to 300μs) are fully adjustable.

Bi-Pulse

(Bi)

Delivers 4 pulses per second to Channel 1 (i.e. the pulse rate of Channel 1 is fixed at 4Hz) while delivering 100 pulses per second to Channel 2 (i.e. the pulse rate of Channel 2 is fixed at 100Hz). Stimulation is burst on for 1 second, then off for 1 second. There illustrates each pulse as a vertical line.  Pulse width (from 50 to 300μs) is fully adjustable.

MODE

Interpretations

Alternate

“A”

The pulses of CHANNEL 1 and CHANNEL 2 are Alternate. When Channel 1 is activated, Channel 2 will be inactivated and vice versa.

In this mode, ON TIME value should be set for more than ramp up value plus ramp down value; OFF TIME value should be set for more than ON TIME value.  For example, if you set on ramp value for 2 seconds, ON TIME should be set for more than 4 seconds (2+2), and OFF TIME should be set for more than 4 seconds.

i.e. ON TIME ≧ Ramp up + Ramp down

OFF TIME ≧ ON TIME

Synchronous

“S”

The pulses of CHANNEL 1 and CHANNEL 2 are synchronous. While Channel 1 is activated, Channel 2 will be activated simultaneously. The pulses active and inactive duration is controlled by ON TIME and OFF TIME.

In this mode, ON TIME value should be set for more than ramp up value plus ramp down value. For example, if you set on ramp value for 2 seconds, ON TIME should be set for more than 4 seconds (2+2).

i.e. ON TIME ≧ Ramp up + Ramp down
