Chapter 6 Proper Measurement
6.1 Wiring method
JK9306 series instruments provide four test wiring input terminals, namely high voltage end, low
voltage end, high current end, and low current end.
Because the voltage and current are floating inputs, there can be multiple combinations of test
wiring methods, and different applications can be connected to the corresponding test circuit.
Here are two recommended wiring methods for the measurement circuit.
Tip: Considering that the presence of distributed capacitance may affect the test, in order to
reduce the impact of distributed capacitance on the test circuit, it is recommended to make the
current test terminal as close as possible to the ground of the input source, that is, the current
terminal is connected to the Low-end.

16
6.1.1 Current terminal internal connection
This method is suitable for low-power testing, that is, the test current is relatively small. It is
recommended to use it to make the current test more accurate, and the voltage measurement
will cause small errors due to the voltage drop caused by the current on the ammeter
(This error can be ignored). The wiring method and brief principle are shown in Figure 6-1:
(Figure 6-1 Ammeter connection method-suitable for small current connection method)
6.1.2 External current terminal
This method is suitable for high-power load testing, that is, the test current is relatively large. It is
recommended to make the voltage test more accurate, and the current measurement will cause
a small error due to the shunting of the voltmeter (this error can be ignored). The wiring method
and brief principle are shown in Figure 6-2:
(Figure 6-2 Ammeter external method-suitable for high current connection method)
Recommended process for connecting test lines:
1) Connect the positive and negative ends of the current in series with the load (connected into a
loop, the negative end of the current is connected to the neutral line);
2) Connect the positive and negative voltage ends to the load or the input source according to
the requirements (that is, the positive voltage end is connected to the live wire, and the negative
voltage end is connected to the current positive end or current negative end);
3) Confirm again that the live wire of the input source is connected to the positive terminal of the
voltage, and the neutral wire of the input source is connected to the negative terminal of the
current.

Chapter 7 Basic Principles and Technical Specifications
7.1 Basic principles
System principle and functional block diagram, as shown in Figure 7-1:
(Figure 7-1 System Structure)
The main structure of the JK9306 series single-phase power meter is to input the voltage and
current of the equipment under test through the instrument to the instrument through
differential input. Through the instrument's internal amplification, filtering, sampling, and AD
conversion, the analog signals of voltage and current are synchronized and sampled. It is
converted into digital quantities Ui and Ii, and then the CPU uses discrete integration to obtain
the voltage effective value, current effective value, active power, and power factor according to
the following formula and sends them to the liquid crystal display. Because the calculation of the
effective value includes the AC component And DC components, and the AC waveform may
become a non-standard waveform due to partial distortion, so the rms calculations here are true
rms values, that is, true rms values. The calculated power also includes the AC and DC
components of the voltage and current. Therefore, the power calculation belongs to the average
power and is also the real power value, that is, the active power. The sign of the power
represents the flow of power (respectively whether the power provided by the power supply to
the load or The energy provided by the load to the power supply). The power factor is the ratio of
the active power to the apparent power (total power). Theoretically, there is no sign of the power
factor. However, in the application of the power meter, the sign of the phase relationship
between voltage and current is determined by the sign of -1. Between ~ + 1, a positive value
represents the voltage leading current and a negative sign represents the voltage lagging current.
In addition to the RMS test mode, this series of instruments also provide AC and DC test modes.
If the input source includes AC and DC components, you can switch modes to view the
corresponding AC and DC components, respectively.
For harmonics, some instrument models do not have a harmonic analysis function, and
instruments with a harmonic analysis function are for power frequency power signals (50 / 60Hz),
and for harmonic results of non-power frequency signals, this series of instruments can View but
no precision indicator. This series of instruments provide optional opening of the 5kHz filter. This
filter is not suitable for non-power frequency power supply and needs to be manually turned off
(optional in the measurement settings). The harmonic order that can be analyzed and viewed is 2
~ 50 times.
