         Specifications D126/1
   
   
Frequency D126 / 1 withstand prolonged overload current (sequential circuits) or voltage (parallel circuit) equal to 120% of nominal. Also device will survive a short-term (up to 5 seconds), overload double the rated current or rated voltage.
    The insulation resistance of electrical circuits frequency counters D126 / 1 relative to the body at a temperature of +20 ± 5 º C must be less than:
    - 50MOm - relative humidity 80%;
    - 2 MW - relative humidity of 95 ± 3%.
    Dielectric strength of current-carrying parts of devices D126/1 with respect to the housing at a nominal humidity (80%) is 1.5 to B almost sinusoidal AC, 50 Hz. Apparatus exposed to the test voltage for 1 minute at a temperature of +20 i +50 ° C.
    Operating position D126/1 - horizontal. Settling time moving part does not exceed 3 seconds. The first garbage arrows do not exceed 150% of its steady-state position.
    The steady-state temperature rise of all elements of the devices over an ambient temperature caused by the heat load equal to the rated current of the rated voltage of n is not more than:
    - 50 ° C - for coils of wire, isolated hlopchatobumazh n th yarn, silk or nylon, impregnated with varnish, as well as for the windings of enameled wire;
    - 65 ° C - for coils of wire with vinifleksovoy metalvinilovoy or insulation;
    - 80 ° C for non-insulated live parts.
    Indications D126/1 may vary for different reasons. Deviations do not exceed the following values:
    - ± 1% of the difference between the final and initial values ​​of the scale for each 10 ° C change in temperature - due to changes in the ambient temperature of +20 ± 5 ° C to any temperature within the operating temperature;
    - ± 1% of the difference between the final and initial values ​​of the scale - due to the influence of external homogeneous magnetic field of 400 A / m, caused by the shock of the same type as the current flowing through the DUT, under the most unfavorable voltage and phase of the field;
    - ± 0,5%, the difference of the final n of the initial values ​​of the scale - as a result of the installation of devices on a ferromagnetic base 3mm thick;
    - ± 1,5% of the difference between the final values ​​of the initial scale n - due to the inclination from the vertical position of the device and any voltage at 30 º;
    - ± 1,5% of the difference between the final and initial values ​​of the scale - due to voltage fluctuation of ± 10% of nominal value;
    - ± 1,5% of the difference between the final and initial values ​​of the scale - as a result of deviation from the voltage waveform is almost sinusoidal under the influence of cue • 2, 3 or 5-th harmonic component equal to 10% of the nominal value.
   
     Operating conditions
   
   
Frequency D126/1 is designed to operate at temperatures from -40 º C to +50 º C. devices can work in pairs produced by marine sea water air humidity up to 98% and provide the correct readings at inclinations of up to 30 º in any direction from the horizontal.
