Production of domestic circuit resistance tester

HTHL-ICircuit resistance testerPerformance Characteristics

1The instrument can use an Android phone or tablet, follow the WeChat official account, and download it exclusivelyAPPControl the instrument through dedicated software, store and upload test data for easy access.

2It has multiple protection functions such as back electromotive force impact, disconnection and power outage during testing, and overheating of the power supply. It can reliably protect against the impact of back electromotive force on the instrument and synchronously sound an alarm.

3Intelligent power management technology ensures that the instrument operates at its minimum power state, effectively saving energy and reducing heat generation.

4High output voltage and wide measurement range.

5The testing current comes from a high-precision high current constant current power supply, without the need for manual adjustment, and the testing is fast and accurate.

6The use of four terminal wiring method effectively eliminates the influence of test line resistance on the test results.

7Seven inch high brightness touch color LCD, clear display under strong light, full touch screen operation, free switching between Chinese and English

8The instrument comes with a perpetual calendar clock and power down storage, which can be stored1000Group testing data, available for review at any time

9The instrument has Bluetooth communication,RS232Communication andUSBInterface, used for computer communication andUDisk data storage.

10Equipped with a panel type micro printer, it can print measurement results in Chinese.
