Feian surface safety meter, electrostatic meter, high resistance meter

TH2690TH2690AH2691TH2691A is a flying safety meter/picoammeter/electrostatic meter/high resistance meter. The flying safety meter/electrostatic meter has a minimum current resolution of 0.1fA (10-16A), which can meet the weak current measurement needs of most scenarios. The built-in 1000V voltage source of the high resistance meter supports measuring resistance up to 10P Ω (1016 Ω). Tonghui provides various adaptive attachments for different testing objects and environments. Different from traditional picometers and high resistance meters

The TH2690 series offers four models, and users can flexibly choose the appropriate instrument according to their actual testing needs.

TH2690TH2690AH2691TH2691A current measurement resolution of 0.1fA with flying safety meter/picoammeter/electrostatic meter/high resistance meter

When studying material properties or determining device performance, it is often necessary to measure limiting currents and resistances such as fA/P Ω, which traditional digital multimeters (DMMs) cannot achieve. The TH2690 series flying safety meter/electrostatic meter provides a resolution of 0.1fA current measurement and 10P Ω resistance measurement, which enables material measurement and can meet current and future measurement needs.

TH2690TH2690AH2691TH2691A Flight safety meter/picoammeter/electrostatic meter/high resistance meter with a data reading rate of 10000 readings per second

The measurement speed is generally determined by the integration period in the integration setting, which is usually an integer multiple of the power frequency period (PLC). On the premise of providing sufficient average times to avoid the influence of power frequency noise on measurement, the shorter the integration period, the better.

Due to the relatively slow reading rate of traditional instruments, they are unable to capture fast transient signals. The TH2690 series has a data reading rate of up to 10000 readings per second, which can capture more precise responses of the tested device.

TH2690TH2690AH2691TH2691A Flight safety meter/picoammeter/electrostatic meter/high resistance meter statistical chart display

The TH2690 series can display test results in real-time in a graphical manner on the main interface, showcasing the dynamic characteristics of the device under test (DUT). There are two types of graphs: curve graphs and histograms.

The picture shows the settings interface:

TH2690 can easily draw various curve graphs, including I-t, V-t, R-t, Q-t, and I-R (specific graphic display functions depend on the product model used). When conducting sensitive measurements, this * and comprehensive graphic display capability can make it easier for you to obtain valuable data.

TH2690TH2690AH2691TH2691A Flight safety meter/picoammeter/electrostatic meter/high resistance meter histogram display

There will be certain noise fluctuations in any measurement environment, so low-level measurement data will have a certain degree of statistical uncertainty. The traditional processing method is to draw a histogram after the measurement is completed to evaluate the measurement data (usually on a computer). However, if you need to perform multiple measurements and test setup debugging cycles, this process will become tedious.

The TH2690 series has a real-time, automatic ruler histogram display function, allowing you to adjust measurement settings in a timely manner without the need for data processing after measurement. The histogram is displayed below the measurement data, making it easy for you to compare the accumulated data on the histogram with the real-time measurement data.

TH2690 can determine and sort the test results. There are two modes to choose from: Grading and Sorting, and up to 7 judgment conditions can be set. The setting interface is shown in the figure on the right:

The Grading mode refers to executing limit judgment until a failure is encountered, outputting the current failure bit, otherwise continuing with the next limit judgment, and if all pass, outputting the last pass bit.

Sorting mode refers to performing limit judgment until a qualified jump is encountered, outputting the current qualified bit, otherwise continuing with the next limit judgment, and if all fail, outputting the last failed bit.

TH2690TH2690AH2691TH2691A Flight safety meter/picoammeter/electrostatic meter/high resistance meter dedicated temperature and humidity probe provides more reliable temperature and humidity data

Temperature and humidity are key parameters in high-value resistance measurement. TH2690 and TH2690A high resistance meters provide temperature and humidity sensor interfaces and are equipped with dedicated temperature and humidity probes. Digital temperature and humidity probes can be used to measure temperature and humidity, providing more accurate temperature data than thermocouples.

Multiple attachments to cope with different testing environments and test items

The TH2690 is equipped with multiple optional accessories to adapt to different tested components, further enhancing its testing effectiveness. Mainly includes resistivity testing box and component testing fixture. The resistivity test box is equipped with electrodes of various sizes, which can be used to measure the surface resistivity and bulk resistivity of materials of different specifications. The component testing fixture is equipped with multiple testing modules to cope with the measurement of various packages such as surface mount devices and axial lead devices.
