Technical data

The final value of the measuring range devices are given in Table. 1
The limit of acceptable basic error of the instrument for measuring and recording the measured value is equal to:
± 1,0% of the final value of the measuring range - for units with the zero mark on the edge of the measuring range when writing ink;
± 1,5% of the final value of the measuring range for devices with the zero mark on the edge of the measuring range when writing ball rod;
± 1,0% of the sum of absolute values ​​of the end of the measuring range - for units with a zero mark within the measurement range when writing ink;
± 1,5% of the sum of absolute values ​​of the end of the measuring range - for units with a zero mark within the measurement range when writing ball rod.
Limit of acceptable total error of instruments ammeter and voltmeter N3092 for recording the measured values ​​ink is ± 1%, ball rod - ± 1,5%.
The total error is expressed as the basic error. Limit of acceptable basic error recording time is equal to ± 0,5%. Record readings ink or ball pivot UPS-3-107-1 ,0-300 TU 25-7733.0008-87 blue tape on the chart in a rectangular coordinate system. The width of the field recording tape - 100 mm.
Limit of acceptable additional instrument error N3092 ammeter and voltmeter to measure and record the measured value caused by 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 .
Limit of acceptable additional error of the instrument for measuring and recording the measured value due to changes in position of the instrument from its normal position in any direction by ± 5 °, and is equal to the limit of acceptable basic error. Limit of acceptable additional error instruments ammeter and voltmeter to measure the N3092 and record the measured value under the influence of an external constant homogeneous magnetic field with induction of 0.5 mT at the most unfavorable direction of the magnetic field is equal to ± 1,0%.
The drift of the zero-line appliance within 30 days of not more than 1 mm. Failure to return a writing device (pointer) to the zero line recording (zero point of the scale) is not more than 1.0 mm. The permissible mismatch baseline applied to the ribbon diagram, with a line record pointer are obtained by setting to zero the scale of not more than 0.5 mm.
The line width of the recording should not exceed 0.9 mm at a speed of 20, 60, 180 mm / hr, 0.5 mm - at all other speeds. Continuous ink recording device for a single ink tank refueling or a ball pivot at least 60 days.
Power supply unit ammeter and voltmeter N3092 is powered by the AC voltage (220 ± 22) (50 ± 1) Hz or (60 ± 1,2) Hz - at the request of the customer. Power consumption of devices on the power supply does not exceed 12 V • A.
To drive the chart tape applied synchronous motor powered by an AC voltage of 220 V, 50 Hz. Upon request, the export performance of devices can be made with the engine power from the AC mains frequency of 60 Hz.
Devices ammeter and voltmeter N3092 have six speeds of the chart paper: 20, 60, 180, 600, 1800, 5400 mm / h, which are set by changing a couple of gears.
Isolation between the housing and all isolated circuits (Chain drawing except timestamps), and 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 is equal to 1.5 kV.
Note. For voltmeters with the end of the measuring range 300V, 500V, 600V insulation between the case and the input terminals, and between the input terminal and the power supply circuit must withstand a test voltage of 2 kV, and for voltmeters with end of the measuring range 1 kV-3 kV. The insulation resistance between the casing and insulated from the casing of any electrical circuit device under normal operating conditions at least 40MΩ.
Limit of acceptable additional error N3092 device changes the voltage from the power supply of ± 10% of rated voltage equal to the limit of acceptable basic error on the measurement and recording of the measured values.
Response time unit N3092 less than 1 s. Dimensions, not more 160h160h250 mm (type 2 GOST 5944-74). Flange size 160x160mm. Unit weight is not more than 4 kg. In accordance with the order unit is shipped with a record of testimony in ink or ink and ball rod. Continuous operation time is not limited.
