Thiết bị điện trở thấp CH2515
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, Giao diện RS232, RS485 interface (không bắt buộc), 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.
Chức năng: Full-scale short circuit clearing function.
Bộ so sánh (sorting) chức năng: Có 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. Tốc độ kiểm tra: nhanh: 100 lần mỗi giây, tốc độ trung bình: 25 lần mỗi giây, tốc độ chậm: 10 lần mỗi giây, precise measurement: 4 lần mỗi giây.
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: nhanh: Về 100 lần mỗi giây; Medium speed: Về 25 lần/giây; Slow speed: Về 10 lần/giây; Precision test: 4 lần/giây.
Phạm vi kiểm tra: CH2515: 0.1uΩ ~ 110MΩ; CH2515A: 1u Ω ~ 20MΩ
