TENS and STIM
1.
Dual channel: individually isolated circuits.
2.
Amplitude: 0-90 mA into 500 Ohm load ; indication only. Actual mA
will tend to be less than indicated due to electrode impedance: at
1000 Ohms load (Electrodes in poor condition) the maximum will be
limited to 70 mA, at 1500 Ohms load the maximum
will be limited to 65 mA.
3.
Type: Constant Current, maximum output voltage 180 Volts +10 / -30
Volts.
4.
Waveform: Asymmetrical, rectangular bi-phasic with zero DC current.
5.
Selectable pulse width: 50
µ
S - 450
µ
S [10% accuracy].
6.
Pulse Rate selection: in the continuous mode 2 – 200 Hz [5% accuracy].
7.
Mode: Continuous, Burst or Modulated.
8.
Burst mode: Bursts of 9 pulses [200
µ
S] at 150 Hz or 185 Hz,
over 2 seconds.
9.
Modulation mode: 6-second cycle of concurrent width modulation and
pulse repetition rate modulation.
10.
Battery: PP3 Alkaline, 9V.
Expected average battery life [of standard 800 mAh, alkaline]: 24 hours.
11. Low Battery Indicator: If the battery goes below 6.9 volts +/- 0.2 volts
the battery symbol will flash on/off once every second.
12. If the battery voltage is below 6.6 (+/- 0.2) volts the unit will not turn
on.
13.
Open Electrode Detect: If an open circuit is detected at
the output of channel A or B the output current will be reset at
zero.
Expected service life:
5 years. Careful use and maintenance extends the life of the unit over the
service life limit.
Physical dimensions:
119.2 x 69 x 28.7 mm.
Weight:
106g without battery, 152g with battery.
Environmental Conditions for use:
+5 to +40 degrees Centigrade. 15-93% Humidity.
Environmental conditions for storage & transport:
-25 to +70 degrees Centigrade. 15-93% Humidity.
