measure resistance R40116
|
The measure resistance & nbsp; R40116 & nbsp; is intended to reproduce the electrical DC resistance in the range of 10 k ... 1 Gohm at trehzazhimnom switched into the measurement circuit during measurement and calibration work
When playing electrical resistance values a constant. current in the range of from 1,05x10 ohms to measure ohms is connected in a measuring circuit for integrating tehzazhimnomu. When this measure is an electrical resistance simulator configured according to the scheme & laquo; star & raquo ;, with fixed nominal resistance values of two of the three beams, settable switches decades & laquo; x10 & raquo ;, & laquo; x10 & raquo; measures resistance and store
equal to 1x10 and 9x10 Ohm, respectively. The nominal resistance value of the third circuit rays & laquo; star & raquo; commutated switches S6 & nbsp; & mdash; S9, corresponding to the four decades of representing a store measures conductivity and indicated on the front panel & laquo; x10 & raquo ;, & laquo; x10 & raquo ;, & laquo; x10 & # 39; & Raquo ;, & laquo; x10 & quot; & raquo; Near limbs respective switches
& nbsp;.
Structurally measure is a desktop device with a vertical front panel & nbsp;.
