Since 1962, the universal multi-range measuring device "Ts-434" has produced the Zhytomyr Electro-meter plant. The device has 37 measurement limits; of which to measure DC voltage 0.5; 2.5; ten; 50; 250; 500 and 1000 c. AC 2.5; ten; 50; 250; 500 and 1000 c. DC 50 and 250 microins; one; five; 25; and 100 ma; 0.5; 2.5; 5 and 25 a. AC current 250 Î¼A; one; five; 25; 100 and 0.5 ma; 2.5; 5 and 25 a. DC resistance 3; 30 and 300 com; 3 and 30 Mom. The basic error of the device when measuring DC and voltage Â± 1% of the final scale value; when measuring alternating current and voltage Â± 2.5%; when measuring the resistance Â± 1.5% of the length of the working part of the scale. The working section of the scale is 100% direct and alternating current. The scale length for alternating current is 77 mm. The scale length at a constant current of 67 mm. Scale length 51 mm. The consumption of the device on the measurement range: DC voltage 50 mk, AC: at the limit of 2.5 to 5 ma; at the limit of 10 in 1 ma; on the other 0.5 ma. Maximum current consumption when measuring the resistance on the limits: X1 24 ma; X10 2.4 ma; X100 0.24 ma; X1000 15 ma; X10000 27 ma. The maximum current flowing through the measured resistance at different limits: X1 24 ma; X10 2.4 ma; X100 0.24 ma; X1000 91 Âµa; X10000 91 Âµa. The voltage drop across the terminals of the device when measuring direct and alternating current on all limits 0.1 ... 0.25 V. The breakdown voltage between the electrical circuits and the housing 3 kV AC voltage of 50 Hz. The dimensions of the device are 150x240x200 mm. Weight 2.6 kg.
