Shop resistance measuring R33 (R-33, R 33)
It is used as a measure DC resistance and enables the production of resistance of 0.1 ohms to 99999.9 ohms.
Accuracy Class 0.2 / 6 • 10 -6.

Shop resistance measuring R33 are used as measures of direct current resistance, and enable us to obtain the resistance of 0.1 ohms to 99999.9 ohms.
Shop resistance R33 is designed to operate at an ambient temperature of 10 to 30 ° C and a relative humidity of 25 to 80% of the operating temperature range. Normal conditions: temperature (20 ± 5) ° C, relative humidity of 25 to 80% of atmospheric pressure 84-106.7 kPa (630-800 mm Hg).
Shops of resistance R33 is exported to countries with tropical climates, suitable for use in dry, heated spaces at an ambient temperature of 10 ° to 35 ° C, the normal operating temperature (27 ± 5) ° C. In this case, the plant designation store should be 04.2 * P33.

Technical data

Accuracy class shopping P33 0.2 / 6 • 10 -6. Limit of acceptable deviation of the actual value of the resistance store as a percentage of the nominal measured under normal conditions, is given by:
δ = ± [0,2 + 6 • 10 -6 (Rc / R - 1)]
where Rk - the greatest resistance value store, Ohm;
R - the nominal value of a resistor in ohms.

The limit of additional error caused by changes in ambient temperature between the upper (lower) limit the range of normal conditions of use and by some point in the related field of application of the operating temperature corresponding to the maximum change in resistance, which is numerically equal to the value determined by the formula set out above.
The limit of additional error in percent of the nominal value when the power dissipation of the face to any value that does not exceed the maximum power under normal conditions of use and steady thermal equilibrium does not exceed the value determined by the formula.
Termokontaktnaya emf in the measuring chain store P33 at fixed switching devices does not exceed 10mkV. The average value of the initial resistance, ie resistance during the installation of the ten-day switches to zero indication shall not exceed 0.06 ohm. The variation of initial resistance due to the change of the contact resistances of contacts switching devices does not exceed 0,006 ohms.
Nominal impedance of one stage of the maximum (maximum on resistance) of the decade - 10000 ohms. Nominal impedance one step lower (lower on resistance) of the decade - 0.1 ohms. Power rating by one notch (with resistance from 1 to 10 4 ohm) 0.25 W (0.1 ohm resistor) - 0.1 watts. The maximum power at one level of 0.5 W (resistance of 1 to 10 4 ohms) 1W (the resistance of 0.1 ohms.) The insulation resistance between the case and isolated dc measurement chain store P33 in the working conditions of application of at least 500MOm.
Isolation between the housing and isolated DC measuring circuit stores P33 stands for 1 min. test voltage of 2 kV value. practically sinusoidal AC 50 Hz. Dimensions 260h185h110mm store. Weight less than 2.5 kg.
