Open Cell Natural Rubber sheet Rubber foam Our G5 series natural rubber foam is made out of natural rubber harvested from rubber trees, plant-based and latex-allergy friendly natural rubber rather than the traditional petroleum-based and limestone-based neoprene. Compared to the traditional neoprene sheets, the natural rubber wetusits production process saves up to 80% on CO2 emissions in one wetsuit. And our all G5 rubber plantations are 100% FSC® certified. FSC® certified means that buying your new G5 natural rubber wetsuit does not contribute to deforestation, human right violations or abuse of agricultural pesticides. It also means that the hevea rubber – the main ingredient G5 natural rubber foam is only extracted from plantations that preserve ecological integrity and biodiversity. Though only 4% of global rubber plantation area is currently FSC®-certified, well-managed FSC®-certified forest management has the potential to affect a positive environmental and social transformation of the natural rubber sector. foamed natural rubber,natural gum rubber Dongguan JinYe Sports Apparatus Co., Ltd , https://www.yuwos.com
Measurement wiring 
Explain the use of three phase phase voltmeter:
1, simultaneous measurement of three-phase voltage or four currents (including zero line current)
2, simultaneous measurement of three-phase AC voltage phase angle, current phase angle, power angle
3, measuring the grid frequency and phase sequence
4, automatic identification of transformer windings, capacitive and inductive loads
5, hexagonal display, color phase sequence analysis
6. Handheld three-phase phase volt-ampere meter active power, reactive power, apparent power, three-phase power and power factor measurement
7, data viewing and saving function
8, data static storage function
9, 3.5 inch TFT color display with touch function
10. Hand-held three-phase phase volt-ampere meter lithium battery power supply, once full can continue standby for more than 20 hours to continue pressing the button for 3 seconds The instrument enters the real power-on state, the meter will emit a “drip†sound, which proves that the instrument has been turned on and then release the button.
2. Measurement interface description
The boot meter automatically enters the measurement interface as follows:
Figure 2. Volt-ampere phase measurement interface
If three-phase three-wire is selected as the measurement method, the three-phase four-line icon will be changed to three-phase three-line with the touch pen. The same operation can achieve single-phase measurement. The instrument has data retention and save function. Touch the HOLD icon. The icon color changes from gray to HOLD. The measurement data is static. The save icon appears below. Touch the save icon to save the data. The data is saved in a loop and the new saved data will be automatically deleted. The earliest saved group of data, the viewing function can view the saved data. The purple icon will use R** (** stands for 01, 02...10) to scroll through the previous page icon and the next page icon. The above functions are also effective on the power measurement interface. Please press the icon power to enter the blue color as shown below to enter the power measurement interface. When the data is saved, the volt-ampere phase measurement data is also saved.
1, single-phase measurement wiring
As shown below:
Figure 5, single-phase electrical wiring
The single-phase electrical measurement connects the live line to the UA phase of the meter and the neutral line to the UN. The current clamp sensor clamps the fire wire to the IA jack.
2, three-phase three-wire wiring method
As shown below:
Line connection: Use dedicated voltage test lines (yellow, red and black), one end is inserted into the UA, UC, and UN phase jacks of the instrument, and the other end is connected to phase A, phase C, and phase B of the measured circuit respectively. phase.
Note: The yellow wire connects to the UA jack, the black wire connects to the UN jack, and the red wire connects to the UC jack.
Current line connection: Insert the IA and IC clamps into the IA and IC jacks of the instrument, and then insert the other end into the current loop to be measured.
