CHAPTER 1 | OVERVIEW
The ENV-421 Amp Meter is designed to show the amount of current produced by an aversive
stimulator.
Figure 1-1 Front Panel Layout
On / Off switch: Turns the device on / off. The LED is lit when the device is on.
Peak and Hold: Shows the RMS current corresponding to the aversive stimulator setting.
Measured in milliamps. It is the metric used by stimulators. The Hold function shows the
maximum amount of recent measurements.
The range of the ammeter is .05 mA to 6.50 mA. Anything below .05 mA is considered 0.0 to
avoid incorrectly reading noise as a stimulus.
Accessories include the 6VDC Power Adapter and alligator clips for connecting to the grid rods.

Connect the +6 VDC adapter to the ENV-421, and then plug the +6 VDC adapter to a standard
wall outlet. Turn on ENV-421.
Figure 2.1 – Connect the ENV-421 to a standard wall putlet and connect alligator clips
Connect the alligator clips on the ENV-421 device to two separate rods on the grid floor. See
figure 2.2
Figure 2.2 – Connect the ENV-421 to your grid floor using the clip leads
Ensure the stimulator you are testing is set to “Dummy Load – out”. Next validate the current by
comparing the current reading on the stimulator with the Peak/Hold reading on the ENV-421.
If there is a deviation on the milliamps being reported between the two devices, please contact
support@med-associates.com for further assistance.
