y v r connecting 250 ohms resistor in series when u cummunicate with BT in bench calibration?..

Answer / vikash suthar

It is because the BT only work if the input impedence is in
the range of the 250 to 600 ohms. so to do make it
communicate we can connect not only 250 ohm but from 250 to
600 ohm any resistor can be connected.
I have experience that even if we connect resisatance 100
ohm it works . below it ,BT not work and up to 900 ohm it
works .but the advisable is from 250 to 600ohm.

Answer / shiva

IT WORKS ON PRINCIPLE MAXIMUM POWER THEORY , WE GET MAXIMUM O/P I.E REQUIRED OPERATIONS AT THESE 250 OHMS,WE GET PERFECT VALUES NEAR R AROUND 250 OHMS.

Answer / mathew thomas elenjickal

It is given so as to compensate the resistance drop in
field. When connected for calibration wires of shorter
legth are connected , so no drop in resistance occours.
The instrument is designed in a way to compensate field
resistance loss.

Answer / prashant pandey

As per my knowledge we usually connect resistor in series to
limit the current to successive device... Here also it
serves the same purpose...
