Seller: milimmd2015 (595) 99.1%, Location: Balti, Moldova, Ships to: Worldwide, Item: 153111159041 M95 Microammeter Also, this device can be called: M-95, m 95, m95, m-95, m 95. M95 magnetoelectric microammeter with multiple interchangeable shunts R4 is designed to measure current and voltage in DC circuits. Microammeters M95 are portable devices on the extensions and are used mainly in radio measurements in laboratory and shop practice. Technical characteristics M95: Measurement limit: - basic-0.1 µa; 1 µa; 10 µa; - additional-1 µa; 10 µa; 100 µa; 5.5 mV; 0.5 mV. Accuracy class: - in the range of 1 µa and 10 µa to 1.0; - at the limit of 0.1 µa-1.5. Inclusion - directly; with external shunt R4. Shunt R4 extends the basic measurement limit 1-5-10-50-100-500-1000 times. The error of adjustment of the shunt resistance, expressed as a percentage of the nominal resistance-no more than ±0,2%. The effect of temperature for every 10° C-no more than ±1%. Influence of external magnetic field of 400 A/m-no more than ±1%.Lin scale M95 - 140 mm. The scale is divided into 100 divisions for devices with a basic limit of measurement of 1 µa and 10 µa and 50 divisions for devices with a basic limit of measurement of 0.1 µa. Indicator light-lamp 6.3 V, 0.25 A with threaded base. Power of the lighting device - from the AC voltage of 127 V or 220 V; from the DC or AC voltage of 6 V. The insulation test voltage is 2 kV. Insulation resistance of electrical circuits at temperatures from +15° C to +25° C and relative humidity up to 80% - more than 109 Ohms. The resistance of the external circuit at the limit of measurement: - 0.1 µa-from 120 kω to 0,1; - 1 µa from 0 up to ∞; - 5 mV-0 to 200 ohms; - 1 µa-from 3 kOhm to ∞; - 10 µa-from 0 to ∞; - 5 mV-0 to 35 ohms; - 10 µa-from 30 Ohms to ∞; - 100 µa-from 0 to ∞; - 0.5 mV from 0 to 200 Ohms. Settling time when the resistance of the external circuit - not more than 4 seconds. Overall dimensions M95-213×270×122 mm. Weight of the microammeter - no more than 3.6 kg. M95 microammeter is designed in a rectangular plastic case with a beveled front part. On the front side of the case there is a limit switch and a contact pad for switching the power supply voltage of the lighting device. On the back side of the case are mounted two clips to include the device in the measuring circuit, the screen clamp and the plug for supplying voltage to the lighting device. The torque in the microammeter M95 is created by the interaction of a direct current passing through the winding of the frame, with a magnetic flux of a permanent magnet. The counteracting moment is created by the extensions serving for fastening of a framework, and also for supply of a current to it. On the axis of the frame mounted holder with a mirror. The beam of light from the bulb passes through a system of lenses and mirrors, falls on the mirror of the moving part and, reflecting, falls on the scale of the device. Calming of the moving part of the device is achieved by currents induced in the frame winding. To set the light pointer to zero is a corrector, the head of which is located on the right side of the device. Operating conditions M95: Ambient temperature - from -15° C to +35° C. Relative humidity at +30° C-up to 80%. The ambient temperature for the performance of M95T - from +10° C to + 45° C. The relative humidity for the execution М95Т at +35° C - to 95%.Note about Payment: PayPal Only;Note about Feedback: Please leave me feedback when you receive your item and are happy with the transaction.
