    Microammeter F195 under the influence of various factors admit the errors in the measurements:
    - A change from the normal temperature to any temperature between 5 º C and 40 º C - value within the allowable error power of the basic error for every 10 º C temperature change;
    - Supply voltage deviates from the normal values ​​by ± 10% - half of the maximum permissible basic error.
    The drift of the zero level that have Microammeter F195 shown to the door, in normal conditions of use does not exceed 1nA / h on the most sensitive measurement range.
    Response time micro-ammeter does not exceed 4 seconds at the level of 98.5% of the set value.    
    Failure to return a pointer microammeter established deviation does not exceed by more than 20% in length.

    Microammeter F195 sets the operating mode for 15 minutes. The duration of continuous operation F195 is at least 8 hours a day.

    Microammeter stand F195:
    - Overload current of 120%;
    - Nine pulse overload current exceeding 10 times the final value of each range of measurement, duration of 0.5 seconds with an interval of 60 seconds;
    - A Surge current exceeding 10 times the final value of each range of measurement, duration of 5 seconds.

    Microammeter F195 designed for use in the following conditions:
    - Ambient air temperature of 1 ⁰ C to 40 ⁰ C;
    - Relative humidity - 80%.
 
    Storage and transport F195

    Microammeter F195 in the manufacturer's packaging is stored at an ambient temperature of 1 ⁰ C to 40 ° C and a relative humidity of 80%.
    Keeping micro-ammeter without packaging is made ​​at an ambient temperature of 10 ⁰ C to 35 ° C and a relative humidity of 80% at 25 ° C.
    Microammeter F195 transported in a package of GOST 9181-74 can be produced by any private transport at an ambient temperature of +50 ° C to +50 ° C and a relative humidity of 95% at 25 ° C.
