That sounds like a battery issue. Make sure the batteries are full strength.
You were correct Charlie, battery low
What is the main difference between the Hz settings is this the pulse setting? How fast on and off? is it better to be higher or lower?
Not necessarily. The pulse setting may be a number below tetany, allowing for relaxation between the individual pulses.
I have a manual with this unit how or what do I look for to know what the reading will be describing?
Typical EMS waveforms are foreign to the body hence the uncoordinated muscular response. I believe this is kind of an individual thing with people responding differently to the stimulation. Again does anybody have any idea how to compare volts to watts in terms of power output?
I don’t know specifically what microcurrent equates to vs. watts. The ARP powers from 0-10 and the recommendation for warm-up and recovery is to set the machine at 2 which is barely noticeable. I will treat the selected muscle group for four repetitions,i.e., for quadriceps I use two pads (one positive, one negative) attached to each leg and perform four body weight squats. That’s it. I may then passively treat the area (no movement) for an additional 5 minutes time permitting. On “non-training” days I’ll perform the same protocol if I’m so motivated.
For muscle strengthening its better to “be higher” as tolerance permits. Recovery and restoration is a different story.
Watts measures work done
Think of a flow of water where volts represents the pressure and Amps represents the amount of water powering the flow, or better, the size of the water pipe that’s under pressure (water pic versus a fire hose).
Here are the specs on the NeuroTrac Sports:
Dual channel: individually isolated circuts.
Amplitude: 0-90 mA; indication only: actual mA will tend to be less than indicated due to electrode impedance.
Type: Constant Current.
Waveform: Asymmetrical, rectangular bi-phasic with zero DC current.
Selectable pulse width: 50uS - 450uS (2% accuracy).
Pulse Rate selection: in the continuous mode 2 - 100 Hz (2% accuracy).
Time duration of the treatment selectable: 1 - 90 minutes.
Low battery indicator: If the battery goes below 6.9 volts +/-0.2 volts the battery symbol will flash on/off once every second.
Open electrode detect: If an open circuit is detected at the otput of channel A or B the output current will be reset to zero.
Ramp up time 0.3 - 9.9 seconds.
If battery voltage is below 6.6 (+/-0.2) volts the unit will not turn on.
Physical dimensions: 108 x 62 x23 mm.
Weight: 0.07KG without battery, 0.1KG with battery.
I looked it up. Seems to be a pretty cool machine and the price is right. We need a report from you on how effective it is. I saw one with two controls over 4 leads/8 pads, using the sticky pads (always the best choice to reduce surface impedance) I’d like to have a look at this when I’m in Aus. Why is it not for sale in the US? Because of compliance or because the US will only allow sales to licenced practitioners? (stupid really, cause the practitioner with the licence could be a hairstylist!)

It is an excellent unit and I have been using it for a while. I have 2 units and got it on sale for $199.00. I purchased it from Healthcare and Rehab specialties 1.800.232.9408 (Edmonton) they may have other offices. They inquired as to my purpose for the unit and I told them I train athletes and we use it for strength and conditioning, they said fine.
You can create 3 different programs in memory and there are 15 preprogramed programs. All of the program parameters you have laid out can be utilized in these units.
I just want to make sure I am using the correct settings Charlie?
