Appareil à faible résistance CH2515

Description

Appareil à faible résistance CH2515

Principales caractéristiques et fonctions:

Easy-to-view display/intuitive operability: haute luminosité, 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, Interface RS232, RS485 interface (facultatif), 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.

Fonction: Full-scale short circuit clearing function.

Comparateur (tri) fonction: Il y a 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: rapide: 100 fois par seconde, medium speed: 25 fois par seconde, slow speed: 10 fois par seconde, precise measurement: 4 fois par seconde.

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: rapide: à propos 100 fois par seconde; Medium speed: à propos 25 fois/seconde; Vitesse lente: à propos 10 fois/seconde; Precision test: 4 fois/seconde.

Plage de test: CH2515: 0.1uΩ ~ 110MΩ; CH2515A： 1ｕ Ω ～ 20MΩ
