Tonghui TH2684 Resistance Tester 10kΩ to 50TΩ 10V – 500V Dual-Output
TH2684/TH2684A High Precision IR Tester is an
intelligent measurement instrument that is used for rapid
measurements on IR properties of electronic parts and
components, dielectric materials, equipments, cables,
etc. Large LCD and user friendly menu provide you
easier operation.
This instrument is especially designed for capacitor IR test
TH2684/TH2684A can achieve rapid measurements
through following methods:
1. Selectable internal input impedance: If the current is
greater than 10nA, only 10kΩ input impedance can be
used; if the current is below 10nA, you can choose 10kΩ
or 1MΩ impedance to test.
2. With the built-in dual voltage output, TH2684 can
charge large capacitors. By dual voltage output, TH2684
is able to output a precharge voltage up to 500V, 200mA.
In voltage follow mode, precharge voltage follow with
the test voltage output and can be finely adjusted.
Above features ensure the perfect charge of capacitive
materials.
3. TH2684A can output a voltage of 1000V, 100mA to
fully charge the capacitive material.
In addition, user can program the sequence measurement
steps (up to 18 steps) on TH2684/TH2684A. For instance,
charge, wait, test, and discharge steps can be programmed.
Each step can last up to 100s.
TH2684/TH2684A has a unique contact detection
function. For capacitive material such as capacitors and
cables, contact detection function can detect the contact
of components under test. Moreover, this detection
function will not increase any test time.
TH2684 equips with interfaces of RS232, USB DEVICE,
SCANNING and Handler. Handler interface provide
convenience for automatic test system; SCANNING
interface is useful for mass measurement of components.
User can use a scanner to speed measurement of
components.
