Technical data

The final value 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 units 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 N3093 devices for recording the measured value is equal to:
± 1,5% - for appliances with the normal region of frequencies, 45-65Hz;
± 2,5% - for appliances with the normal region of frequencies, 45-1000Hz, - the final value of the measuring range.
Limit of acceptable basic error recording time is ± 0,5%. The allowed limit additional error instruments due to changes 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 in temperature.
The allowed limit additional error N3093 devices to measure and record the measured value caused by changes in the position of devices from its normal position in any direction by ± 5 °, and is equal to the limit of acceptable basic error.
The allowed limit additional error N3093 devices to measure and record the measured value under the influence of an external uniform magnetic field, the time-varying sinusoidally with a frequency equal to the frequency of the current flowing through the measuring circuit device under test, under the most unfavorable direction and phase of the magnetic field equal to the limit acceptable basic error. The magnetic induction:
for a frequency of 50 Hz and 1000 Hz - 0.5 mT;
for a frequency of 10,000 Hz - 0.05 mT.
The allowed limit additional error N3093 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 devices and recording of measured values ​​caused by the deviation of frequency, equal to the limit of acceptable basic error:
frequency deviation of ± 10% of the normal limits of the frequency range - for units with a normal frequency region 45-65Hz;
frequency deviates from the limits of the normal range of frequencies up to any frequency in the working frequency range - N3093 for devices with a normal frequency region 45-1000Hz.
Limit of acceptable additional error of measurement devices and record the measured value due to changes in supply voltage of ± 10% of nominal, equal to the limit of acceptable basic error.
Limit of acceptable additional error of measurement devices and recording the measured values ​​due to the stress placed back to back with him of the same instrument, used to be located at a distance of 1 m is equal to ± 0,5% of full scale range.
Time setting the readings does not exceed 2., The value of the first pointer Swapping does not exceed 7% of the width of the field recording. The drift of the zero-line appliance within 30 days of not more than 1.5 mm. Failure to return a writing device (pointer) of the device to the zero line (the zero point of the scale) is not more than 1.5 mm. A disagreement of the zero line of the diagram printed on the tape, with the line entries received when the cursor to the zero mark of the scale, not more than 0.75 mm.
The line width of the recording is not more than 0.7 mm. Warm-up time 1 hour of continuous operation time is not limited. Record readings made ball rod UPS-3-107-1 ,0-300 or blue ink on chart paper with holes on a nominal width of 100 mm field of the record. Power supply device is supplied from the AC voltage (220 ± 22), (50 ± 1) Hz or (60 +1.2) Hz - at the request of the customer.
Power consumption devices N3093 does not exceed:
measuring circuit - 1V • A;
food chain - 12V • A.
Continuous ink recording device for a single ink tank refueling or a 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 N3093 sold for export. Nominal values ​​of the chart speed tape 20, 60, 180, 600, 1800, 5400 mm / h
Variation of the substitution is made changeable gears. The insulation between the casing and insulated from the housing electric circuits of the device (other than the application time stamp circuit) as well as insulation between the separate circuits to withstand normal operating conditions for 1 min. test voltage of the AC frequency (50 ± 1) Hz, the mean value of which is:
