CH2515 Low Resistance Apparatus

설명

CH2515 Low Resistance Apparatus

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, 핸들러 인터페이스, RS232 인터페이스, RS485 interface (선택 과목), USB HOST, USB DEVICE

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, effective range: 2 ω, 20 ω. Test voltage ≤60mV.

기능: Full-scale short circuit clearing function.

비교기 (sorting) 기능: 있다 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. 테스트 속도: 빠른: 100 초당 횟수, medium speed: 25 초당 횟수, slow speed: 10 초당 횟수, precise measurement: 4 초당 횟수.

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: 빠른: ~에 대한 100 초당 횟수; Medium speed: ~에 대한 25 회/초; Slow speed: ~에 대한 10 회/초; Precision test: 4 회/초.

테스트 범위: CH2515: 0.1uΩ ~ 110MΩ; CH2515A： 1ｕ Ω ～ 20MΩ
