La description détaillée de marque:Directive limits of output voltage of simulator from 0 to 2011 microwave with
directive discreteness 0, 1 microwave.
resistances significance, simulating the internal resistance of èçìåðè
òåëüíîãî electrode (Rè) and the limits permissible main relative
inaccuracy of these resistances make up 0; 500 +- 10% and 1000+-10%ÌÎì.
resistances significance simulating the internal resistance âñïîìî-
ãàòåëüíîãî electrode (Râ) and the limits permissible the basic error
these resistances make up: 0; 10 + - 1% and 20 +- 1% lump.
the output resistance of simulator in case of Rè=Râ=0 makes up not more
0, 55 lumps by 1 microwave of output voltage.
the limit permissible main absolute setting error âûõîä-
Noy voltage of simulator should not exceed significances, determined
from the formula: delta = +- (0, 005Ux+0, 1),
where delta - main absolute error, microwave;
Ux - set value of output voltage, microwave.
voltage intrachain of auxiliary electrode and clamp "I" /IIII
simulator (EMF "Çåìëÿ-ðàñòâîð") must the matter 0; ìèíóñ1, 5 +-
0, 2 in and plus 1, 5 +- 0, 2 V.
the insulation resistance of high-resistance contact of nest "of meas." îòíîñèòåëü
but clamp "I" /IIII is to be no less than 5*10^12 Omagh.
the insulation resistance of electric circuits of simulator concerning
clamp "I" /IIII is to be no less than 10^9 Omagh.
the simulator food is carried out from two normal elements
Gost 1954-75 And "element 316" Gost 12333-74.
overall dimensions, not more, MM - 240 kh 155 kh 140.
