        1.3 specifications

        1.3.1 IPI-100 It provides in normal conditions of use measurement tangent tg & delta dielectric loss; and measuring the capacitance Cx of objects in the ranges and the main measurement error below:

        A range measuring dielectric loss tangent of 5 10-4 to 0,3;

        -limit permissible absolute basic error in the measurement of the dielectric loss tangent for the total capacitance of the measuring range of the test voltage at a frequency of:

        50 Hz + (5. 10-4 + 0,05 tg & delta;)

        54 Hz + (1. 10-3 + 0,13 tg & delta;)

        measurement range at the test voltage capacitance:

        100 kV from 5 pF to nF 3;

        50 kV from 6 pF to 10 nF;

        - maximum permissible basic error in measuring the capacitance at the frequency:

        0.5 pF 50Hz Cx + 0.03 < / p>

        54 Hz 0.5 pF Cx + 0.04;

        - measuring the voltage range of 10 to 100 kV;

        - maximum permissible relative error in the measurement of RMS voltage at a frequency of:

        50 Hz +3%;

        54 Hz +3%

        Note: The meter will convert the dielectric loss tangent, and. . Measurements at the frequency of 54 Hz to 50 Hz

        1.3.2 limit of tolerable additional measurement error caused by changes in ambient temperature from normal (20 & plusmn; 5 & deg; C) to either within the working area, does not exceed half the maximum permissible primary measurement error (n. 1.2.2) for every 10 degrees. . Temperature changes

        1.3.3 FPI 100 allows the measurement of & laquo; direct & raquo; and & laquo; inverted & raquo; measurement schemes that provides a measure of insulation objects parameters as with isolated or grounded pin.

        1.3.4 IPI-100 provides the output of measurement results on the liquid crystal display (LCD) display unit. Communication between the measurement unit and the display unit is carried on a radio channel in the frequency range 845-945 MHz. Stability of the radio at a distance 5-7 m level is provided in transmitter output power of 1 mW.

        1.3.5 Image numbers and symbols on the display distinguishably at least 0.8 m at an external illuminance of 10 to 1,000 lux .

        1.3.6 IPI-100 under normal operating conditions and the application is ready to operate for no more than 1 minute after switching.

        1.3.7 Duration of operation is determined by power consumption meter used electrochemical accumulators . When the battery capacity of 1800 mA & bull; h duration of at least 10 h

        1.3.8 MTBF for the operating conditions of application of at least 4000 h

        1.3.9 average period.. service meter & ndash; at least 8 years.
