1. The ray's first action is to short-out the Main Computer input terminal . 2. The AC power cable is connected to the rectifier input terminals . 3. Consequently, receiver AFE antenna input terminals must be protected. 4. MicroAngelo also supported a light pen, connected through input terminals on the top of the card. 5. Input terminals p and n are internally grounded.6. The DC input terminal of a DVR is connected to an energy storage device of appropriate capacity. 7. The heuristic rule is to ensure that the impedance " looking out " of each input terminal is identical. 8. An operational amplifier can be described as a voltage source dependent on the differential input voltage between its input terminals . 9. On earlier Avometers, this may be done by short-circuiting the input terminals and selecting the most sensitive direct current range. 10. Alternatively, a voltage buffer may be used before the amplifier input, reducing the effective source impedance seen by the input terminals .
