1. First, according to the measured quantity and its estimated size, select the corresponding measuring gear and the appropriate range. 2. When the size of the measured object cannot be estimated, it is necessary to first use the high-range gear, use the test pen to measure the time, measure the size range of the pole, and then switch to the appropriate gear. 3. When the object to be measured is a resistor, no matter which range of the electrical block is used for measurement, it is necessary to adjust the force before the measurement. The method is to short the two carbon pens and adjust the zero potentiometer to make the pointer (multi-purpose pointer) Table) means that the zero point or the indication of the resistance scale value (digital multimeter) is exactly zero. If the adjustment zero potentiometer cannot achieve this, the battery should be replaced. 4. The maximum value of each range of electrical blocking is “infinityâ€, obviously it is not possible to represent the range. Usually, the median resistance of each range is electrically blocked to reflect their range. The indication of each electric blocking position is the gear. The median resistance (the so-called median resistance refers to the resistance value indicated when the pointer points to the midpoint of the scale). The measured value of the measured resistance value near the median resistance is more accurate. 5. When using the voltage block to detect the voltage of the two points of the circuit towel, special attention should be paid to the relative relationship between the internal resistance of the used gear and the resistance between the two points tested. Only when the internal resistance of the block is far greater than the resistance between the two points tested. The measurement results are credible. 6. The pointer multi-meter should be placed in the high voltage of AC/DC voltage after use; the digital multimeter should be turned off after use.
Antenk extended its connector product range by SD card connectors. As already mentioned there are various applications, in the past driven by the computer industry, which are using memory cards as well in their end products, single sided pressure contact connectors can be designed and manufactured according to a customer specific requirement based on customer dedicated insulator- and contact dies. Such single sided pressure contact connectors are mainly used as board to board connection on the base of direct contact to the pads on the board.

Compact Flash storage cards are small, removable, mass-storage devices. They electrically comply with Compact Flash Association standards, the PC Card ATA standard, and run in True IDE mode. These 50-position cards typically hold between 32 MB and 2 GB of memory and are about the size of a matchbook. Antenk`s connectors include headers that can accept Type I (3.3mm thick) or Type II (5.0mm thick) storage cards, flush and raised mounting heights, and ejectors. Antenk Compact Flash card connectors also provide electrostatic discharge protection.Adapter for Compact Flash Card type I and II
