This accessory for the SS72L Microelectrode Amplifier adds manual DC offset control via an external control box. The control box has two offset adjustment knobs:
The 1.8 m (6′) cable terminates in a 2.5 mm, 4-pin, audio plug to mate with the audio jack on the SS72L.
Offset control is necessary for many extracellular recordings including BSL PRO Lesson A17 Frog Heart – Intracellular* Action Potentials.
*Note: A17 is an “extracellular” recording but because all heart muscle cells in close proximity to each other have almost identical action potential amplitude and timing, it’s labeled an “intracellular” recording.
