3) OPERATION
Follow the above steps to operate correctly the resistance box.
• Select the desired resistance in the decade through the
rotary switches, pay attention to the chosen multipliers. For
measurement and use of this resistance use the outputs 0
and 1111110Ω.
• If you need a ground point or reference uses a banana-
banana wire for short-circuit the points 0 and the earth.
• Do not short-circuit the points 0 and 1111110Ω.
• When to use the decades of low ranges remembers of that
the accuracy is guaranteed since that the contact resistance
is compensated.
•
For measure the contact resistance, leave all the rotary
switches in zero position and measure the residual value of
resistance (between 0 and 1111110Ω).
