CH2515 Апарат с ниско съпротивление

Main features and functions:

Easy-to-view display/intuitive operability: high brightness, ultra-clear 4.3-inch color LCD display; Easy to operate and intuitive to use;

Basic setting operation is simple, direct reading, percentage error and sorting results; Multiple parameters are displayed simultaneously.

The comparator judges that the lamp is displayed directly, without looking at the screen, and the operation efficiency is improved.

Rich interfaces, Handler interface, RS232 интерфейс, RS485 interface (по желание), USB ХОСТ, USB УСТРОЙСТВО

High-precision temperature test function: temperature can be tested by temperature sensor.

Reliable contact detection function can automatically detect whether the test terminal is well connected to avoid misjudgment.

Low voltage test function, ефективен диапазон: 2 ω, 20 ω. Test voltage ≤60mV.

функция: Full-scale short circuit clearing function.

Компаратор (сортиране) функция: There are 12 files of sorting data built in, which can judge the HI/LOW of the tested piece.

Elimination of thermoelectric potential: it can eliminate thermoelectric potential, minimize the influence of thermoelectric potential, and improve the test accuracy of small resistance.

Ultra-high speed and ultra-high precision measurement can improve production efficiency. Тествайте скоростта: бърз: 100 times per second, средна скорост: 25 times per second, ниска скорост: 10 times per second, precise measurement: 4 times per second.

Reliable 4-terminal measurement.

The allowable value of wiring resistance under low resistance range is 1.5 ω; Even under the measuring current range of 1A, the test cable can be easily extended.

CH2515/A test accuracy: test current accuracy: 5% sampling speed: бърз: относно 100 times per second; Средна скорост: относно 25 пъти/секунда; Бавна скорост: относно 10 пъти/секунда; Precision test: 4 пъти/секунда.

Test range: CH2515: 0.1uΩ ~ 110MΩ; CH2515A： 1ｕ Ω ～ 20MΩ
