Technical data
Maximum permissible error of the instrument Ammeter Э539 a percentage of the final range values in the normal range of frequencies and direct current equal to the values given in the table.
Accuracy class, the final value of the measuring range, frequency range Ammeter Э539 correspond to the indicated in the table.
Normal values of influence quantities correspond to GOST 8711-78. The time does not exceed 4 seconds.
Devices in tropical version can have a normal temperature different from 20 °C if specified in the purchase order, in this case, the normal temperature is indicated on the scale of the instrument.
The limit of additional error device Ammeter Э539 alternating current if the frequency deviates from the normal range of frequencies up to any frequency in the working frequency range is equal to the limit of permissible basic error.
The maximum permissible error of the instrument Ammeter Э539 caused by the change of ambient temperature from normal to any temperature in the range of operating temperatures, equal to ±0,5 % from end value of measuring range per 10 °C change in temperature.
The limit of permissible additional error caused by the influence of humidity is equal to the limit of permissible basic error.
The resistance and inductance on the measurement range does not exceed the values specified in the table and on the device.
