500V				1.00 TΩ
1000V				2.00 TΩ
2500V				5.00 TΩ
5000V				10.0 TΩ
10000v				20.0TΩ
testing time
Setting range		Adjustable from 10 seconds to 99 minutes
Test power
Fixed test voltage			100V, 250V, 500V, 1000V, 2500V, 5000V,10000V

Product Appearance

1.Capacitive touch screen.

Display size 7 inches; resolution 1024600.

2.Test the power supply "+" positive electrode output terminal.

3.GUARD(Protection ring) terminal.

4.Test power supply "-" negative electrode output terminal and the test line shield layer connection terminal.

The terminal above is the test line shield connection terminal.

The lower terminal is the negative output terminal of the test power supply "-" terminal.

5.Start and stop test button, with RGB color backlight.

Press the test for 2 seconds to start the test, and press to stop the test. When the key backlight is green, the test has stopped; if red, the test is in progress.

6.Menu button. Short press to quickly enter the main menu interface.

7.Return the button. Quickly return to the previous interface or exit the current feature.

8.Power button. Long press for 2 seconds to start power, long press for 2 seconds to shut down.

9.Single key shuttle, with RGB color backlight.

You can quickly adjust the cursor position, adjust the value, the key is equivalent to "confirm" key.

10.RS232 communication interface, optional RS485 communication interface.

11.Excellent disk interface. To store test data and instrument upgrade firmware files, use FAT or FAT 32 format disks.

12.Power interface. Built-in charger AC power input, built-in 250V 2A fuse.

13. charge lamp.

Red: in charge; green: full.

The built-in charger has the maximum charging time limit of 5 hours. Once the charging time exceeds 5 hours, the charging function will be automatically turned off, and the charging indicator light will go off.
