Designed to measure and record current and voltage values ​​in DC circuits. The limit of permissible error in measuring and recording the measured value is ± 1.5% of the final value of the measurementOverall dimensions 230x180x315mm. Portable microamperillivoltmeters H399 (hereinafter referred instruments) are used for measuring and recording current and voltage values ​​in direct current circuioperating conditions of the device are ambient temperature from 0 to 50 ° C, relative air humidity up tat a temperature of 25 ° C. H399 microampermillivoltmeters supplied to tropical climatic areas are deto operate at an ambient temperature of 10 to 45 ° С and relative humidity up to 95% at a temperatur ° С and indoors without sharp changes in temperature, exposure to solar radiation, rain and dust. Pethe action of molds and other biological factors. In this case, the factory designation of the device msupplemented with lettersundefined “04.2”. Technical data The margin of permissible basic errormeasuring and recording the measured value is ± 1.5% of the final value of the measuring rangeinstruments with a zero mark at the edge of the range and of the sum of the final values ​​of the measrange – for instruments with a zero mark within the measuring range. Final values ​​of measuring ran1mV; 5mV; 10mV; 25mV; 50mV 75mV; 250mV; 1B; 2.5V; 5V: 10V; 25V; 50V; 100V; ten; fifty; 250 μABy agreement with the manufacturer, a self-recording Micro amperillivoltmeter Н399 / 1 is made on sorder with the following final values ​​of the measurement ranges: 5mV; 10mV 25mV; 50mV; 100mV; 10 μA; 25μA; 50 μA; 100 μA; 10B
External resistance in the measurement ranges with upper limits from 1mV to 250mV, at which the dproperties of the H399 device (quieting, transfer) are guaranteed, no more than 10kOhm External resvalues ​​(R ext) in the measurement ranges with upper limits from 1V to 100V on undefined dynamproperties of the device do not affect. The margin of error of the device for recording time ± 0.5%. Thof permissible total error of devices for recording the measured value is ± 1.5%. The total error is expin the same way as the basic error. The limit of permissible error of the H399 instrument for measurinrecording the measured value caused by a change in the position of the instrument from the normal pin any direction by ± 5 ° is equal to the limit of the permissible basic error. The limit of permissible adderror of the device caused by a change in the supply voltage by ± 10% of the nominal value or the freof the supply network by ± 2% of the nominal value is equal to half the value of the limit of the permibasic error. The limit of permissible additional error of the H399 instruments for measuring and record
