CH2515 Low Resistance Apparatus

Popis

CH2515 Low Resistance Apparatus

Hlavní vlastnosti a funkce:

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, Rozhraní manipulátoru, rozhraní RS232, RS485 interface (volitelný), USB HOST, USB ZAŘÍZENÍ

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.

Funkce: Full-scale short circuit clearing function.

Komparátor (sorting) funkce: 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 rychlosti: rychle: 100 krát za sekundu, střední rychlost: 25 krát za sekundu, slow speed: 10 krát za sekundu, precise measurement: 4 krát za sekundu.

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: rychle: o 100 krát za sekundu; Medium speed: o 25 krát/sekundu; Slow speed: o 10 krát/sekundu; Precision test: 4 krát/sekundu.

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