☆ Calibration
of DC electrical measuring instruments |
|
• Calibration of DC voltmeter and ammeter: the device has a built-in DC voltage
standard source with an output range of 10 mV ～ 1550 V and a DC
current standard source with an output range of 1 mA ～ 600 A. The voltage and current accuracy of the 0.02 level device
reaches 0.01 level, which is applicable to the calibration of DC voltmeter or
ammeter of 0.05 level and below. • Calibration of DC power meter: a virtual power standard source composed of
independent DC voltage and current output. The accuracy of a 0.02 level
device reaches 0.02 level, which is applicable to the calibration of DC power
meters of 0.1 level and below. • Calibration of DC transmitter (option): The secondary DC signal measurement
function of the optional transmitter supports the maximum DC 12 V or 24 mA
signal input. With DC voltage, current and power standard sources, the
proportional error of the transmitter can be detected. |

• Application scenario 1: The maximum DC voltage output is
1550 V, meeting the requirements of 1.15 Un voltage test of 1 kV electrical
energy meter; The maximum DC current output is 600 A, meeting the
requirements of 1.2 In current test of 100 A electrical energy meter. With
the power pulse measurement function, the test of direct connected DC watt
hour meters for measuring DC electrical energy can be completed. • Application scenario 2: The instrument has 10 μV~4.4 V four
wire small signal voltage source, with 1550 V DC voltage source and electric
energy pulse measurement function, can carry out the verification of indirect
access DC electric energy meters. • Application scenario 3: The maximum output of DC current is
up to 600 A, which can be used as the primary current input of the DC shunt.
With 1550 V DC voltage source and power pulse measurement function, the
overall verification of the DC shunt + indirect connected meters for measuring
DC electric energy can be achieved. |

|
• DC high current standard source: the maximum output is 600 A, which
can be used as the primary current input of the DC shunt. • DC small signal voltmeter: support voltage input range is 10 μV~4.4 V, which can
measure the secondary output voltage of the DC shunt. • Special low thermal potential wire and terminal block: it can reduce the measurement
uncertainty introduced by contact potential and thermoelectric potential. • Verification and test of DC shunt (option): it can measure the resistance value
and basic error of the shunt, and draw R (I) and R (t) curve. |
