Measure-imitator R4085 (R-4085, R 4085, p4085, p4-085, p 4085)

Measure-R4085 imitator - a device for comprehensive verification of high impedance bridge DC at an ambient temperature of 15 to 30 ° C for 1 Gohm resistance from 10 to 35 ° C for resistors 10, 100, 1000 G W and a relative humidity of 80%.
The measure of resistance R4085 refers to recoverable products.
 
Technical characteristics
 
The basic error of the device R4085 expressed as a percentage of the nominal resistance shall not exceed the values ​​specified as Table. 1, with the following standard conditions:
ambient temperature (20 ± 2) ° C;
relative air humidity of more than 80% but,
The actual resistance value of 1 G W at t ° C in the temperature range of 15 ... 30 ° C is determined by the formula:
1011 Rt = [(t -20) + (t -20) 2] Ohm
Changes in nominal resistance devices measure resistance R4085 (excluding G W 1) at ambient temperature changes in the range of 10 ... 35 ° C, does not exceed one-half the allowable value of the basic error for every 5 ° C change in temperature.
The insulation resistance between the measuring circuit measures resistance R4085 (terminals "1", "2", "0") and the screen (terminal "3") at least October 13 ohms between the screen (terminal "3") and housing at least 5 · October 11 ohms.
Dielectric strength test voltage device 2 kV. MTBF working conditions of application of not less than 2500 hours average lifetime of at least 8 years.
Dimensions of the device are not whiter 120h130h300 mm. Mass measures the resistance R4085 less than 3 kg.
