H13-15 : Precision Animal Shocker (Manual settings only)
This research grade, precision feedback, current-regulated shocker is totally isolated (floating output) for operator and subject safety, as well as isolation from other sources of electrical stimulation such as physiological stimulators that may be in use concurrently. Isolation is achieved by using an isolated transformer along with optical isolation of the inputs from the control equipment.
The unit can function as a two-pole (bipolar) current reversal "square wave" output, or as a scanner distributing the polarity reversal across an 8-pole output for grid floor applications. Mode selection is made by a switch on the back.
The grid outputs are direct "Form C" semiconductor switches. The "off" grids have zero resistance so the subject receives the same current regardless of the number of grids contacted.

The H13-16 may be programmed from 0 to 5 milliamps in 20 microamp increments by a 0-2.5 Volt signal via the Programmable. Input on the back of the case. The signal is generated by the Graphic State Notation control program and comes from the Programmable. Output on the back of the Habitest Linc or you may also use a D/A converter output.

The A13-16 Shock Level Tester allows for verification of the shock output of a shock source. This unit requires a
Volt Meter and/or Oscilloscope (not included). The input jack connects to alligator clips (included) that can easily
be attached to either subject electrodes or the grids of a shock floor.
This unit provides two output options for verification. The first is a rectified DC output that can be used with any standard volt meter. This output will be consistent with Ohms Law, V (volts) = I (amps) * R (ohms), where the internal resistance load used is 10 kilohms. Because this output circuit contains diodes and filtering, the voltmeter output will be slightly lower than predicted.
In order to meet the requirements of more rigorous verification, the second output provided is for connection to an oscilloscope. This output will follow ohms law precisely. The maximum amplitude of the output pulse will be exactly equal to Ohms Law.
