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, Hanteerder koppelvlak, RS232-koppelvlak, RS485 interface (opsioneel), USB -gasheer, 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.

Funksie: Full-scale short circuit clearing function.

Vergelyker (sorting) function: 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. Test speed: vinnig: 100 times per second, medium speed: 25 times per second, slow speed: 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: vinnig: about 100 times per second; Medium speed: about 25 times/second; Slow speed: about 10 times/second; Precision test: 4 times/second.

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