| Portable Wheatstone Bridges (Modified) with Verley & Murray Loop Test
(1128 D ) |
This bridge is exactly same as cat. no. 189 except for additional facility of murray and varley loop test for location of faults in cables. The bridge is also suitable for resistance measurements.
For resistance measurements and varley loop test, there are 7 multiplying factors of x 1000, x 100, x 10, x 0.1, x 0.01 and 0.001.
For murray loop tests, 3 additional multiplying factors of 10 m, 100 m and 1000 m are provided.
Special switching arrangement has been provided to carry out conductance tests, varley loop test and murray loop test.
Rest of the features like series arm, battery, galvo, push buttons are same as in cat. No. 1128 C.
A) Constantan Coil : Accuracy ± 0.1%.
B) Manganin Coil : Accuracy ± 0.02%.
