With its convenience of handheld measurement, TH2822C can perform the measurement of basic LCR parameters easier and faster and simultaneously meet the requirements of fast and convenient measurements in many occasions such as field maintenance test, external carrying test, fixation point on production line or mobile checkout, warehouse in-and-out checkout of electronic components, real-time spot or batch inspection and especially in field measurements. While its advantage of cost performance over bench meters makes it possible for most related testers to configure it.
Identical test function and performance with bench meter
The basic measurement accuracy is 0.25%, 40,000 counts on primary display is the highest in the identical handheld LCR meter, D/Q counts resolution on secondary parameter is 0.0,001, which can be applied to the accurate dissipation measurement and makes it possible for the handheld LCR meter to measure low dissipation and ESR capacitors such as metallization, mica, NPO(COG)ceramics. TH2822C supports fast test response, up to 4 times per second, similar to the bench meter, which changes the history of slow and blunt testing speed of handheld LCR Meters.
No worry for differences of component test result
For traditional handheld LCR meters and some bench LCR meters,internal resistance of signal source changes with testing range. When measuring some components with high dependence on electric level, different devices obtain different results, for instance, impedance values of inductive components vary with test current, capacitance of ceramic capacitors with high Q values changes with test voltage and the change of internal resistance of signal source will cause the inconformity of testing result. TH2822 first achieves the use of 100 Ohm constant source internal resistance on handheld LCR meters, when all popular bench LCR Meter adopt 100Ohm signal source internal resistance. Whereupon, the test results of common or level sensitive elements are reliable and comparable.
Combination of low-cost and high-accuracy as two test port configurations selectable
TH2822 achieves configurations of 5-terminal and 3-terminal port (patent technology). There are two configurations available,inexpensive banana plug and crocodile clip used in simple measurement and 5-terminal test rabbet, four terminals or SMD 4-terminal testing tweezers used in high-accuracy 4-terminal Kelvin measurement on lead components or SMD components.
Longest battery life in this industry
When you are annoyed to swap out batteries on a continual basis, TH2822C helps you to allay your worries with its low dissipation of more than two times as long battery life as the other meters. With the elaborate low consumption design, TH2822C has the lowest dissipation in similar meters with the working current of 22mA (1 kHz, 100 Ohm load). The low consumption design makes the work-hour of the built-in battery last for 16 hours. In the case of power-off or external power, the standby current of the built-in battery is as low as 2μA.
Auto LCR Select: Easy use for non-expert
There are various test parameters and equivalent modes of series-parallel connection in TH2822C , which is extraordinarily suitable for professional measurement. Nevertheless, most non-experts are hard to identify inductor, resistor and capacitor in that most RC-components are almost identical in appearance. By using Auto LCR, users can identify tested components easily and obtain measurement results immediately. All you need do is press the key of LCR AUTO, then according to the properties of tested components, the meter will automatically select appropriate group test parameter and equivalent modes of series-parallel connection. For operators, it is quite valuable for the inspection of various scrambled components, the classification of SMD mixed components, the feeding of components or the debugging before warehousing.
Fast realization of mobile data acquisition
Mini-USB interface is the standard configuration of TH2822C. Like cell phones and digital products, TH2822C can connect to desk or portable computer rapidly by USB interface and set up acquisition platform of testing data anytime and anywhere. Automatic sending function of testing data and even interactive control by SCPI are available on TH2822C.
