Bridge DC UMV
Also, this device can be called: YMB
UMV bridge DC intended for:
- measurement of resistance by the Wheatstone bridge circuit;
- cable measurement scheme Varley;
- cable measurement scheme Murray;
- the inclusion in the diagram as a shop resistances.
Measurement accuracy - up to 0.5%.
All parts are mounted on the bridge UMV laminated bakelite panel, which is placed in a box. All arms are mounted on plastic parts, which pressed into contact.
Leverage is a comparison of the bridge resistor, which consists of four decades 1'100 ohm, 1'10 ohm, 1'1 ohms, which are connected in series.
Comparative shoulder gives the opportunity to include the resistance of 1 ohm to 9999 ohms in steps of 1 ohm.
The ratio of the bridge arms UMV set with the switch in the position of 1:1000, 1:100, 1:10, 1:3, 1:1, 10:1, 100:1.
When measured with a DC bridge UMV can use internal and external galvanometer.
When using a galvanometer recommended the following modes bridges UMV:
On the UMV derived bridges terminals for connection of the measured resistance for connecting external galvanometer for the power supply and terminal to check the bridge arms. Panel switches are comparative arm and shoulder relations, as well as the switch, the switching bridge circuit with a loop or noose Murray Varley.
The manufacturer guarantees the conformity of devices DC bridges UMV all the technical requirements provided the customer terms and conditions of use, storage and transportation of installed documentation manuals.
