Single-double bridge P3009 (P 3009, P-3009, r3009, r 3009, r-3009)
P3009 is designed to measure electrical resistance in DC within the range from 10-8 Ohm to 1.11111 1010 Ohm.
Accuracy class from 0.1 to 1 depending on range.
Single-double bridges P3009 (hereinafter - bridges) balanced with the elementwise calibration and adjustment are designed for measurement ranges from 10-8Ohm to 1.11111 1010 Ohm of electrical resistance in DC with shown in Table 1. ambient air temperature and relative humidity less than 80%.
Single-double bridge Р3009 designedfor areas withtropical climate should be marked as Р3009Т4. 1. Bridge adjust must be done after device receiving from warehouse and setting it in the room or when ambient temperature changes differ from those shown in the Table 1.
Single-double bridge P3009 is produced in accordance with specifications. Measurement ranges. accuracy classes and operating temperature ranges are shown in Table 1. Single-double bridge P3009 consists of a measuring block (MB), automatic compensator (AC) and amplifier (A).
Acceptable basic error limit of Bridge P3009 (in percentage of nominal measured resistance value) do not exceed value that is numerically equal to bridges P3009 accuracy class at normal operating temperature with less than 80% relative humidity (Table 1).
Changes in P3009 bridges accuracy error at operating temperature ranges shown in Table 1. do not exceed maximum permissible basic error when the ambient temperature changes:
for every 5 ° C - accuracy classes 0.01. 0.02. 0.05. for every 10 ° C - accuracy class 0.1. 0.2. 0.5.
As a zero indicator (ZI) AC and A blocks are used. AC Block must be installed in a horizontal position. AC output scale accordingly to positions of AC sensitivity switches are:
1 - 10-1 V/divider;
2 - 10-2 V/divider;
3 - 10-3 V/divider;
4 - 10-4 V/divider;
5 - 10-5 V/divider;
6 - 10-6 V/divider;
7 - 10-7 V/divider;
8 - 10-8 V/divider.
AC block timereading response in measurement range (0.5-0-0.5) 10-6 V does not exceed 4 sec. Electric zero corrector provides zero offset regulation "01" - not less than 4.5mkV, regulation "02" - not less than 4.5 mkV. regulation" 03"- not less than 0.15 mkV.
90 min zero drift of AC block does not exceed 1 mkV if MEASUREMENT option is not used. Output index fluctuations caused by shemes elements noise do not exceed 0.03 mkV.. Exceeding specified value, certain emissions are allowed.
Insulation resistance and insulation dielectric strength at temperature range from 10-35 ° C with relative humidity up to 80% - are not less than values shown in Table 2.
Dimensions of Р3009 bridge blocks do not exceed:
blockMB - 490 х 210 х 520 mm;
block АC - 240 х 225 х 150 mm;
block A - 440 х 210 х 210 mm.
Weight of Р3009 bridge blocks do not exceed:
block MB - 15 kg;
block АC - 3 kg;
block A - 8 kg.
