Purpose of the development: Microohmmeter TSS4105 is designed to measure the electrical resistance of the DC components of electrical circuits which are not energized.

Recommended application field: Electric power.

Technical characteristic: - Display of measurement results microhmmeter - alphanumeric display on the LCD ( LCD display ) , the robot interactively . - Power microhmmeter - AA size batteries voltage 1.2 V - 8 pcs. - Measuring ranges microhmmeter : 10 mkOm to 3 milliohms ( Limit 3 milliohms ); from 1 to 300 mW ( 300 mW limit ); from 0.1 to 50 ohms ( Yield 50 ohms). - Modes microhmmeter - automatic or manual. - Automatic operation - one measurement after tapping the " Measurement " . - Manual operation - continuous measurements for holding the button "Measure " button for manual selection of measuring range 1-300 mW with a limit of 300 mW or 0.1-50 ohms with a limit of 50 ohms. - Manual operation microhmmeter preferred for measuring the resistance of the inductive nature . Continuous operation microhmmeter manually defined electric battery capacity . - Accuracy class according to GOST microhmmeter 2.5 8.401 " Accuracy classes of measuring instruments. General requirements . " - When measuring the resistance of the inductive nature with a time constant of 50 ms to be within the error of acceptable relative basic error . - Power consumption current Microohmmeter battery in manual mode is not more than 0.25 A. - The current in the circuit resistance measurement : at the limit of 3 mW - 5 A, a current pulse duration of 0.3 seconds ; at the limit of 300 mW - 50 mA DC ; at the limit of 50 Ohm - 5 mA DC . - Dimensions - 230 mm x 140 mm x 58 mm. - Average life microhmmeter 10 years.

Advantages over analogues: - The newest multifunctional microohmmeter TSS4105 with digital readout; - Automatic selection of the measuring range.

The development stage readiness: Introduced in production

Description of the development:
()
Microohmmeter can be used for the measurement : - Transient electrical resistance high-voltage switches and circuit breakers ; - Electrical resistance of brazed , welded and bolted connections ; - The electrical contact resistance and resistance ground connection of the grounding circuit devices; - Resistance tires, wires and cables ; - Resistance of windings of electrical machines. Microohmmeter provides: - Charge the battery from the power supply ; - Light indication of the process and the degree of battery charge ; - Automatic selection of the measuring range ; in manual mode allows manual selection of measuring range of 300 milliohms or beyond 50 ohms ; - Automatic disconnection from the power supply when the voltage drops below 8 V supply and (or) after (90 - 120) to the end of the measurement ; - Storage of the results of last 20 measurements. Operating conditions ( climate impacts ) - Ambient air temperature of minus 10 * C to 55 * C; - Relative humidity 90 % at 30 * C. Degree of protection in accordance with GOST 14254 " Degrees of protection provided by enclosures (code IP)» for microhmmeter - IP42.
