The attention of the dielectric constant and the dielectric loss meter
1, the test process can not let the unrelated persons close, because this test instrument can produce a higher voltage, without the trained personnel can not use the equipment. When the test must have the guardian, not single use. In case of accident..
2, a long time without the use of equipment, in the re-use, the first instrument no-load pressure once, that the high-voltage electrode wiring from the pressure ball. Check the computer test interface to see if the high voltage is normal..
3, the accident occurred in the test to cut off the power, the problem can continue to test the problem.
4, the device is placed smoothly, the ground to strengthen the ground. It is best to cement the ground to avoid resonance.
5, the equipment in the use of the housing to protect the ground, the equipment casing to earth, to protect the operator and equipment operation safety.
6, after the use of the device, to turn off the system parts of the power, not charged plug power line.
7, according to the power supply voltage access equipment. Make sure the circuit is correct. Otherwise damage equipment.
8, the instrument should be placed indoors, laboratory should be clean, dry, corrosive media, non personnel do not arbitrarily operation.
9, don't let cable equipment encountered sharp edges, so as not to cut the cable insulation; don't let cable in under heavy pressure, to avoid pressure broken cable caused by fire; don't cable pull objects or objects tied with a cable, so as not to pull off the cable so that the device is not functioning properly.
10, do not let the equipment encounter water splash, corrosive gas, combustible gas and combustible material. If you don't avoid it, possibly fire..
11, devices, to cut off the power supply equipment, is to unplug the plug from the socket. No equipment or equipment moving down tilt angle of 45 degrees or above.
12, do not plug the power plug in the device when the device is running.
The characteristics of dielectric constant and dielectric loss detector:
Automatic Q \ \ the company's innovative value technology, the measuring resolution of Q to 0.1Q, the resolution to 0.00005 tan.
Can the solid insulating materials in the dielectric loss angle of 10kHz ~ 120MHz (tan delta) and Permittivity (epsilon) change test.
The tuning circuit of residual low inductance to guarantee 8nH, 100MHz (Tan d) and (E) the error is small.
The special multi parameter LCD screen menu display: Q value, frequency tuning, etc..
The Q value range automatic / manual range control.
The synthesis of DPLL 1kHz ~ 60MHz, 50kHz ~ 160MHz test signal. Independent signal source output port, so this machine is a synthetic signal source.
The test device complies with GB/T 1409-2006, ASTM D150 and IEC60250 American Standard specifications.
Dielectric constant and dielectric loss detector inductors:
According to the test frequency requirements, the need to configure the amount of inductors.
For example, when the frequency of the 1MHz test, with 250 H inductor, at the 50MHz test frequency, with 0.1 H inductor, etc..
High frequency medium sample (optional parts):
In the current high - frequency dielectric material verification system, the calibration department is the high - frequency dielectric loss meter and the measurement standard is the high - frequency standard medium sample.
The sample by artificial sapphire, quartz glass, alumina ceramics, PTFE, epoxy boards, and other materials made with diameter of 50mm, thickness 1 ~ 2mm test samples. Users can order according to the need to ensure the repeatability and accuracy of the testing device.
Range of working frequency is 10kHz ~ 120mhz, it can complete test material in the working frequency of high frequency dielectric loss angle (tan delta) and dielectric permittivity (epsilon) changes.
The instrument in the test apparatus is composed of plate capacitor and measuring cylinder linear capacitor and a parallel plate capacitor is usually used to quilt sample, equipped with the Q table as indicating instrument.
Insulating material loss angle tangent value is through the sample into the panel capacitor and not setting out the Q value of the changes in the thickness and the scale reading calculated by the formula.
Similarly, the cylindrical linear electric micrometer
