The TENS D77 is a twin-channel unit designed to provide electrotherapy with particular emphasis on TENS therapy (Transcutaneous Electrical Nerve Stimulation).

1. Multifunctionality

The unit's memory contains a bank of 59 therapeutic programs (each with several subprograms) used for the most common ailments and injuries. Two outputs with independently adjustable parameters permit simultaneous performance of two TENS therapy sessions.User's own settings can be stored in the memory. The unit is capable of operating in CC (constant current) and CV (constant voltage) modes. Its features include electrodiagnostics (I/t curve) and electrode wear measurement.

A new feature of the D6 series units is the electrode resistance measurement. It is done with leads specially designed for this purpose, colored blue. One wire is connected to an electrode, the other to a spot electrode. The measurement is done by applying and slightly pressing the spot electrode to the surface of the silicon electrode.

TENS D77 has a large LCD display so its interface is very legible and transparent. For your comfort and work pleasure we put central knob (for setting parameters) and located patient cable nest in front of unit. Thanks to new features and unit possibilities operating TENS D77 is intuitive.

2. Full twin-channel capability

With its modern twin-channel design, the TENS D77 permits performing simultaneous therapy on two patients.

The TENS D77 can operate in two modes: constant current (CC) and constant voltage (CV). The difference lies in the parameter that is stabilized - for CC the current is maintained stable, for CV - it is voltage. The CV mode is available only for currents generated in one channel (and thus not for, e.g. interferential currents) and is used for contact work (e.g. with simultaneous electrotherapy and ultrasound therapy).

4. Built-in therapy programs

The unit's memory contains a bank of therapy programs developed for most frequent ailments and injuries. In performing electrostimulation, users have at their disposal several therapy programs for each of 76 ailments.

5. User's program memory

The unit is capable of storing user's own therapy programs and waveforms in 40 cells of memory. A maximum of eight such sets can be stored. If a stored set is used, the unit will automatically switch currents during therapy.

6. Types of current generated

• TENS currents: symmetrical, asymmetrical, symmetrical-interval, modulated, burst,
• microcurrents (unipolar and bipolar).

7. Technical parameters

• therapy duration: 0 - 99 min,
• dimensions: 105 x 255 x 202 mm,
• weight: 1.8 kg.

8. Automatic electrodiagnostic feature

The TENS D77 like other units of the D7 series, offers the capability of automatically calculating drawing an I/t curve and quantitative testing of the nervous-muscular system.
