Interscale Demonstration Meter, 5mA / 100mV FSD Lab Supplies_Lab Burner Accessories supplying the third-color signal line

supplying the third-color signal line for breadboarded circuits where black and red rails are already assigned

yielding a flatter field profile for plane-of-symmetry demonstrations

sized for higher-resistance work where milliampere-level currents need to be set without overheating the component
