For engineers often deal with "electricity", "safe" security factor is always in the first place.The multimeter is an electrician necessary testing tools, so the use of the multimeter security for a line of engineer, is especially important.As everybody knows, there is a built-in fuse multimeter in current gear, purpose is to ensure that when the test current, will, multimeter concatenate loop once overweight or at risk, the current loop current fuse can and time-division, ensure the safety of the instrument especially operators.
How to choose the appropriate fuse?
In order to ensure the instrument and the safety of the user, choose a suitable and safe fuse is particularly important.FLUK雷竞技appE FLUKE) multimeter are equipped with high energy, ultra-fast response original fuse, make sure that the accident, the instrument can quickly block may cause danger.Fluke original fuse has been to meet even higher than international safety standard strict request for design criteria.
The advantage of fluke fuse:
1. The rated voltage 1000 v, 20 ka 11 a fuse breaking capacity.Original high-energy fuse can not only in the continuous rated power flow fusing, instantaneous electricity flow in high fuse immediately, ensure security and quick response
2. The ceramic tube encapsulation, arcing ability is strong, high reliability.Special design of the original high-energy fuse inside filled with sand, when the temperature of explosion energy and produced sand melting, needed to absorb energy and isolating explosion combustion air
The dangers of using the wrong fuse:
Instrument burned;Pens and melting;Casualties.
Prefer not to install the fuse, also do not install a common fuse!
How to quickly detect the fuse is good or bad?
Will play to the multimeter Ω gear, A pens and only can, plug in part to the Ω jack, using the tip into "A" and "mA/uA" jack, if you have any reading shows good fuse (" A "jack readings should be 0-0.5 Ω," mA/uA "jack readings should be around 10 k Ω), if the show" OL ", indicates the fuse burned.
