Universal multi-range measuring device "Ts-434".
Instruments for adjusting and controlling the PTA.Since 1962, the Zhytomyr plant "Elektroizmeritel" has been producing the universal multi-range measuring device "Ts-434". The device has 37 measurement limits; of them for measuring DC voltage 0.5; 2.5; 10; fifty; 250; 500 and 1000 c. AC 2.5; 10; fifty; 250; 500 and 1000 c. DC 50 and 250 μA; one; five; 25; and 100 ma; 0.5; 2.5; 5 and 25 a. AC 250 μA; one; five; 25; 100 and 0.5 ma; 2.5; 5 and 25 a. DC resistance 3; 30 and 300 rooms; 3 and 30 Mohm. The basic error of the device when measuring direct current and voltage is ± 1% of the final value of the scale; when measuring alternating current and voltage ± 2.5%; when measuring resistance ± 1.5% of the length of the working part of the scale. The working section of the scale at DC and AC 100%. Scale length on alternating current 77 mm. DC scale length 67 mm. The length of the resistance scale is 51 mm. Consumption of the device on the measurement range: DC voltage 50 mka, AC: at the limit of 2.5 V 5 mA; at the limit of 10 to 1 ma; on the remaining 0.5 ma. Maximum current consumption when measuring resistance on the limits: X1 24 ma; X10 2.4mA; X100 0.24mA; X1000 15mA; X10000 27 ma. Maximum current flowing through the measured resistance at different limits: X1 24 ma; X10 2.4mA; X100 0.24mA; X1000 91 μA; X10000 91 mka. Voltage drop at the terminals of the device when measuring DC and AC current in all ranges of 0.1 ... 0.25 V. The breakdown voltage between the electrical circuits and the case is 3 kV of alternating voltage with a frequency of 50 Hz. The dimensions of the device are 150x240x200 mm. Weight 2.6 kg.
