Resistance Tester Usage
Martial Arts Mat is an EVA Mat, in double
colors for reversible, in 100cm x 100cm, offering 2cm, 2.5cm, 3cm and 4cm
thickness.
EVA martial arts mat is made from Eco-friendly, high
density, closed cell, non-smell and non-toxic EVA foam material. With
interlocking edges, each mat can be connected easily without any loose.
It is always used as EVA Tatami Mat, EVA Jigsaw Mat, EVA Taekwondo Mat, EVA Karate Mat, EVA Judo Mat, EVA Jiu Jitsu Mat and EVA Aikido Mat. The thick
foam provides a protection for trainers when they fall on the floor. Also we
have 3 different textures for surface of the mats, which is "T" texture, five
strips texture and tatami texture. All of them provide a good traction to the
feet.
The
colors we usually offer for the martial arts mat is blue & red, blue &
yellow, black & red, single black. Or we can offer customized colors based
on customers` requirement.
We used
heard many of customers complained about the bad experience on the bad smell
mats they purchased from other supplier. Indeed, that may cost a lower even
half of our price, it is because the EVA foam material is what we call
second-hand material, its smell will make people uncomfortable. Melors promise
that the EVA foam material we use would be never second-hand foam material,
what we offer is truly non-smell and non-toxic.

(a) Grounding resistance tester (b) Connecting cable (c) Measure the grounding rod 1. Disconnect the connection point between the grounding trunk and the grounding body, or disconnect the connection point of all grounding branches on the grounding trunk.
2. Insert two ground rods into the ground 400mm deep, one from the grounding body 40m away, and the other from the grounding body 20m away.
3. Place the rocking watch in a flat place near the grounding body, and then perform wiring.
(1) Connect the grounding body E' of the wire stub E and the grounding device on the table with a connecting wire.
(2) Use a connecting wire to connect the wire post C on the watch and the grounding rod C′ 40 m away from the grounding body.
(3) Use a connecting wire to connect the wire post P on the watch and the grounding rod P′ 20m away from the grounding body.
4, according to the measured grounding body ground resistance requirements, adjust the coarse adjustment knob (there are three adjustable range).
5. Shake the shakes evenly at about 120 rpm. When the hands are deflected, the jog dial is adjusted until the hands are centered. The reading after setting with the fine-adjustment dial is multiplied by the coarse-adjustment positioning multiple, which is the grounding resistance of the measured grounding body. For example, if the fine tuning reading is 0.6, and the rough adjusted resistance positioning multiple is 10, then the measured grounding resistance is 6Ω.
6. In order to ensure the reliability of the measured grounding resistance, the bearing should be changed and retested. Take the average of several measured values ​​as the grounding resistance of the grounding body.
