Technical data
The final values ​​of the measuring range devices are given in Table 1. Limit of acceptable basic error on the measurement and recording of the measured value is equal to:
± 1,5% - for devices with a normal region of frequencies of 45-65 Hz;
± 2,5% - for devices with a normal frequency region 45-1000 Hz, the final value of the measuring range.
Limit of acceptable total error N393 devices for recording the measured value is equal to:
± 1,5% - for devices with a normal region of frequencies 45-65Hz;
± 2,5% - for devices with a normal region of frequencies 45-1000Hz, - the final value of the measuring range.
Limit of acceptable basic error on the record time is ± 0,5%. Limit of acceptable devices additional error caused by the change in ambient temperature from normal to any temperature in the range from 0 to 50 ° C, equal to the limit of acceptable basic error for every 10 ° C change.
Limit of acceptable additional error N393 devices to measure and record the measured value, due to changes in position of the device from its normal position in any direction by ± 5 °, equal to the limit of acceptable basic error.
Limit of acceptable additional error N393 devices to measure and record the measured value under the influence of an external uniform magnetic field, the sine poloidal changes in time with a frequency equal to the frequency of the current flowing through the measuring circuit of the test device, in the most unfavorable direction and phase of the magnetic field is limit of acceptable basic error. The magnetic field:
for a frequency of 50 Hz and 1000 - 0.5 mT;
for a frequency of 10,000 Hz - 0.05 mT.
Limit of acceptable additional error N393 devices to measure and record the measured value, caused by the installation. ferromagnetic shield thickness (2 ± 0,5) mm, equal to ± 0,5% of full scale range. Limit of acceptable additional error of measurement instruments and recording of measured values ​​caused by the deviation of the frequency equal to the limit of acceptable basic error when:
frequency deviation of ± 10% from the end of the normal range of frequencies - for units with a normal region of frequencies 45-65Hz;
frequency deviation from the normal limits of the frequency range up to any frequency in the working frequency range - for units with normal N393 frequency region 45-1000Hz.
Limit of acceptable additional error devices to measure and record the measured value, due to changes in supply voltage of ± 10% of nominal value equal to the limit allowed by the basic error.
Limit of acceptable additional error of measurement instruments and recording the measured value, due to the influence placed back to back with him of the same device to be located at a distance of not less than 1 m, is ± 0,5% of full scale range.
Response time unit is less than 2 s., Index value of the first flip does not exceed 7% of the width of the field recording. The drift of the zero-line appliance within 30 days of 1.5 mm. Failure to return writing device (pointer) of the device to the zero line (zero point scale) of 1.5 mm. Allowable difference of zero line indicated on the chart tape recording with the line obtained when the pointer to the zero mark of the scale, not more than 0.75 mm.
The line width of recording up to 0.7 mm. Warm-up time 1 hour. Continuous operation is not limited. Write the results produced ball pivot UPS-3-107-1 ,0-300 blue or ink ribbon diagram perforated with a nominal width of 100 mm field recording. Power device is supplied from the AC voltage (220 ± 22), frequency (50 ± 1) Hz or (60 1.2) Hz - on demand.
Power consumption is less than N393 devices:
measuring circuit - 1 V · A;
food chain - 12 V · A
Continuous recording device with a single ink tank refilling ink or one ball pivot at least 60 days. To move the chart tape applied synchronous motor powered by an AC voltage of 220V, 50Hz or 60 Hz for devices N393 is exported. Nominal values ​​of travel speed chart tape 20, 60, 180, 600, 1800, 5400 mm / h
Speed ​​change is the replacement of replacement gears. Insulation between the body and insulated from the electrical circuits of the device (except chain deposition time stamps), and isolation between separate electrical circuits under normal operating conditions is alive withstand for 1 minute. Impact of testing AC voltage frequency (50 ± 1) Hz, RMS value is: 1.5 kW - for ammeters, voltmeters, to be included in current transformers and voltmeters direct connection with finite values ​​ranges 15V, 25V, 50V, 150V, 250V.
Note. Voltmeters for direct connection with end of the measuring range of 500 and 600 V insulation between the body and the measuring chain, and between the measuring circuit and the power to withstand the test voltage 2kV.
