Q:Do not use thread holder to make crystal head

Continue propping cable and crystal head, first use the word play to press the plastic block in the groove of the crystal head, cable will be fixed, and then use another vise (also available hard things will all end flat) the first crystal metal sheet and press until flush with the surface of crystal head, finally a word from one metal pad to press the fixed date, a little attention here, not under the pressure of vertical tilt, press 4 or 5, the two line generally does not use, you can try the handle, then the interval root pressure, do not tilt.

Q:If there is no wire pliers, how should I get the crystal head?

The crystal head square on the table, put a small screwdriver or a flat hacksaw. The head of the copper tin crystal alignment, must pay attention to the founder, don't put up with a hammer blade steel hammer gently, not too much force, because of the bad hammer.

Q:How are the external clamps defined in the drilling?

Q:What is voltage clamp and patch clamp? Brief description of its principle and Application

It can be used to determine the ionic current when the cells are excited. The change of membrane permeability is rapid, but if a high frequency response amplifier is used, the injection current can be adjusted continuously, rapidly and automatically so as to keep the membrane potential constant. It can measure the membrane potential, membrane current and postsynaptic potential of cells.

Q:What's a pipe wrench for?

Because the connections between them are screwed by the pipe thread, the force is very large, and no special tools are not available.

Q:The use of mt87 caliper type multimeter

The brake caliper exists on the disc brake. When the vehicle is running, the brake disc rotates with the wheel, and the brake caliper is stationary. When braking, the brake clamps the brake disc to complete the braking action

Q:When the voltage clamp is used, what is the electrode instability of the current measurement?

Before measuring, should first check whether intact core rubber insulated clamp. The jaw should be clean and free of rust, and there is no obvious gap after closure.

Q:What's the difference between a ratchet wire cutter and an ordinary wire cutter?

Easy to compress, if not accustomed to people, it will feel tight after the bad opening, ratchet, network pliers in the middle of a knob, each time after the pressure of the crystal head, to twist the knob to pull out the cable.
