- the indicated voltmeter for the conversion of the conversion factor is carried out by transferring it to 30 input voltage of a given magnitude. This voltage is measured, and the corrected voltage is calculated, as the voltage rises due to the residual voltage resulting from the loss of voltage.
- the factor is taken into account by multiplying the calculator by changing the voltage to the voltage of the ⁇
- the voltage measuring device is connected to a series-connected voltage amplifier, a voltage converter and a voltage converter.
- This direct current is therefore a direct voltage overvoltage switch.
- the live voltage is supplied to the input of the digital voltmeter and the voltage is restored to constant voltage.
- the internal calculator calculates the off-load factor as a constant voltage, from the constant-voltage - 3 - Live voltage is applied to a constant voltage, which is a result of a voltage overload.
- the result of the measurement is
- test site For the most part, the test site
- a wide voltmeter of variable voltage is known, which is connected to measuring and test channels, each of which is connected to the investigative system.
- the test voltage is a short-circuit with a variable voltage.
- the transmission coefficient is not in error, but the error of this transmission coefficient is included in the result of the error.
- a long electrical switch disconnects the voltage and voltage at the input of the specified voltage switch.
- An electric switch has a fault that is incapable of a strong voltage amplifier.
- the digital voltmeter of the effective value of the alternating voltage makes it possible to increase by more than two times the accuracy of the measurements.
- FIG. I disclose a block diagram of digital technology
- Amplifier output 7 alternating voltage through the first voltage divider 9 is connected to the input of the switch 2, in-
- the output of the 4-phase converter is connected to the mains voltage when the mains voltage is switched on.
- the pre-calculated calculator 17 also contains a converter 28 on time during the digital input, the output is disconnected from the output, the output is disconnected from the output 19
- the digital voltmeter of the effective value of the alternating voltage works two ways in the following way.
- the switch 2 and switches 2 and 6 are located in the "I" position, the key II will open.
- the measured voltage ⁇ ⁇ through the switch 6 is connected to the input of the amplifier 7, the voltage is amplified and switched on to the voltage of 8
- the voltage of the integrated DEA of the integrated amplifier 12 is equal to zero, which is a constant component of the output voltage of the amplifier 7, but also the input voltage is 5 volts.
- ⁇ -- the one-factor amplification factor of the amplifier 7 is the variable voltage and the nominal is the power factor of the 8th voltage amplifier; 5 ⁇ - ⁇ " (partial) the fault of amplifier 7 and the multi-component fault of the device 8 are respectively.
