Voltage and current calibrators МВ4303, МВ4305, МА4302, МА4304 (MV4303, MA4302)
Country: Ukraine · Model: MV4303
Calibrators МВ4303, МВ4305, МА4302 and МА4304, often written as MV4303 or MA4302, reproduce DC voltage (МВ) and DC current (МА). They verify and calibrate working instruments of accuracy class 0,5 and higher, and serve as working standards.

Description
МВ4303 reproduces DC voltage from 1 mV to 1500 V in seven subranges, with resolution from 1 µV. Accuracy class is 0,1/0,002 to 0,2/0,06 depending on subrange. Load current reaches 100 mA. The instrument shows the error of the device under test and settles within 2 s after setting. Warm-up takes 30 min; continuous operation lasts up to 16 h. Power consumption is up to 250 V·A; dimensions 485 × 510 × 215 mm. Used by metrology services and verification labs to calibrate voltmeters, ammeters and multimeters, and by instrument manufacturers.
How to choose
Start with the quantity to reproduce: voltage needs МВ4303 or МВ4305, current needs МА4302 or МА4304. Then match the range and accuracy class to the instruments under test. Confirm kit, verification and version with a USK ENERGY manager when ordering.

FAQ
Are МВ4303 and MV4303 one calibrator?
Yes. Cyrillic МВ and Latin MV denote the same instrument, as МА4302 and MA4302 do.
What is the difference between МВ and МА?
МВ calibrators reproduce DC voltage, МА calibrators DC current.
What is the range of МВ4303?
1 mV to 1500 V DC in seven subranges, resolution from 1 µV.
Which instruments do these calibrators suit?
Verification and calibration of instruments of accuracy class 0,5 and higher, such as voltmeters, ammeters and multimeters.
Is a warm-up needed?
Yes, 30 min for МВ4303. Afterwards it can run continuously for up to 16 h.
