2. Current conversion measurement:The instrument is equipped with a special measuring interface for the transducer, which can simultaneously supply power to the transducer and measure its secondary signal. It can be connected to a precision current transducer (such as TH0540) to expand the current range to 500 A, 1 kA or even greater. The primary current of the measured transducer can be directly displayed by setting the ratio of the current transducer on the instrument.

 

☆ DC comprehensive measurement

1. The instrument supports DC, DC ripple and other measurement modes, the DC ripple measurement bandwidth is up to 10 kHz.
2. DC ripple measurement function is very suitable for verifying the verification device of electric energy meter with ripple output function.

2. Application Scenario 1: It can be used to calibrate shunt or other I/V transformer with stable large current sources and precision current transducer.
3. Application Scenario 2: With precision voltage measurement function, it can be used to assess the verification equipment for indirect connected DC electrical energy meters.

 

☆ Power calculation function

1. The instrument has the power calculation function. Users can connect voltage divider, shunt, transformer and other range extenders externally, set the ratio k and offset b, measure the secondary output signal x of the range extenders, and then calculate the actual value of the primary power to be measured according to the function f(x)=kx+b.
