Excellence faeth FT338 multimeter

FT338 multimeter, industrial data communication with the true RMS multimeter is a positioning in the high-end handheld digital multimeter products. FT338 multimeter is specifically for industrial measurement of advanced multimeter, low-pass filtering, its unique function, can accurately measure the motor speed, plays a very important role in the motor drive and related electrical equipment inspection and maintenance work. At the same time, it has the 4-20mA% signal detection function can be used in the industrial field and factory automation control equipment with current transmitter detection and troubleshooting. FT338 multimeter basic accuracy of 0.03%, the frequency range is as high as 20KHz, which can be very good to meet the relevant requirements of the industrial field measurement work. Believe familiar multimeter friend must know, the current high-end multimeter market is basically dominated by foreign brands, so faith (Faith) the FT338 multimeter with what strength to enter this market, but the market retail price of 2500 yuan in the domestic high-end multimeter is he excels, I will lead you to find out.

In recent years, faith technology into the hand-held digital multimeter, and the entry point of market positioning for high-end products. Due to the high end of the main attack, so I believe you can not see in the tens of millions of dollars in the low-end Multimeter Market (Faith) brand. As the FLUKE's deep red, yellow, the green with Huayi, faith (Faith) will be blue as their main theme with million meter product color. Therefore, if you see some engineers holding a blue frame of the high-level multimeter, it may be the product of Faith. The appearance of the classic design in FT338 multimeter overall design used in high-end multimeter classic shape, large table body design, size of about 205mm * 95mm * 50mm, LCD screen size is relatively large, about 66mm * 40MM, expand the table bracket body the multimeter can be used as a table table placed on the desktop. FT338 frame covered by a hard rubber material, so as to enhance the body resistance and increase the friction with the appearance and the desktop. The weight of the table is about 500g, is not easy to use in real time by accident drag line pen. Faith design in accordance with the requirements of the industrial level, with military standard GJB quality, which the production and manufacture of products put forward high standards. FT338 automatic range multimeter, no power button switch is independent of the choice of different measurement function will automatically open the multimeter through the function selection dial switch, the function of turntable feel good, gear clear, smooth rotation. FT338 start faster, startup takes only one or two seconds, the screen will display "FT338" logo, and then choose a good measurement project, with a hand can get a pen. FT338 use 4 AA alkaline battery, life time indicators have a maximum of 200 hours, there is a low-voltage battery alarm function. In the trial, we used 4 NiMH rechargeable batteries, the same as the multimeter. FT338 has a good power management performance, when the battery power shortage will automatically disable some of the cost of electricity functions, such as recording, backlight function, as far as possible to continue the use of basic functions.

Multimeter appearance

FT338 by opening the rear fuselage battery cover and replace the battery fuse. The use of a single screw screwdriver to replace the plastic cover on the battery cover. FT338 is the use of the fuse of the German SIBA fast fuse type explosion-proof arc extinguishing safety tube, in the flow will be rapidly fusing, in order to prevent damage to parts.

Battery case and fuse holder

FT338 using two fuses, respectively SIBA 500mA and SIB A10A fuse. SIBA fuse fuse performance is very good, fast, and low resistance, little impact on the measurement, far better than the cheap fuse tube, there is no "bombing", therefore, FT338 provides a good protection function, overvoltage protection nominal reached 1000V. To cause dangerous situation (such as the wrong pen in voltage test mode into the current pen test hole, once the misoperation will cause short circuit), a buzzer alarm screen prompt and continuous use, current test block, if the internal fuse is damaged, will also be indicated on the screen. FT338 on top of a USB interface, can be connected with the computer machine, taking into account the dust problem, the increase of protective cover for the USB interface and USB interface for the general interface, it can be more convenient for users to connect the computer. At the same time, the use of USB interface transmission with respect to the use of traditional infrared transmission mode, greatly improve the transmission bandwidth, but the lack of infrared transmission unique photoelectric isolation characteristics. FT338 uses 2 M601 optical coupler in PC data transmission circuit design, increased isolation, through a CP2102 USB bridge chip provides USB port.

Fine workmanship kernel has been strong, good work is the basic guarantee of high quality instruments, is the basis for safe and stable and durable. Good things are not afraid to be opened to see the internal circuit board, which is also known as the Wai Wai show. Loosened back 4 screws, FT338 can open. From the internal circuit board, FT338 uses a multilayer board and SMD components, the entire plate making and component welding are relatively neat. For the key areas of the motherboard, FT338 have done a shielding treatment, to prevent the interference of the external high frequency signal multimeter measurement. The utility model is characterized in that the utility model has the functions of a rotary table and a key area of the plastic surface
