Description:

 

Launch ES300 High-Voltage Insulation Resistance Tester supports Short-Circuit Buzzer Tests.

 

Launch ES300 High Voltage Insulation Resistance Tester is used for Insulation Resistance, AC/DC Voltage, Resistance, and Short-Circuit Buzzer Tests.

 

An insulation resistance tester, commonly known as a megohmmeter, is a portable instrument specially designed to measure the insulation resistance of electrical equipment and lines. It outputs high-voltage DC(with adjustable voltages of 500V, 1000V, 2500V, and 5000V.

 

Launch ES300 Insulation Resistance Tester outputs high-voltage DC, applies it across the insulation medium under test, and converts the detected weak leakage current into an insulation resistance value, so as to determine whether the insulation layer has hidden risks such as moisture, aging, damage, or breakdown.

 

Launch ES300 supports insulation testing of high-voltage components such as new energy high-voltage wiring harnesses, battery packs, motors, electronic controls, cables, and power distribution boxes.

 

Polarization Index (PI) Measurement:

The polarization index is measured through the meter's automatic measurement function, which automatically measures the resistance at 1 minute and 10 minutes respectively. Pass/Fail is automatically displayed at the two time points.

 

Dielectric Absorption Ratio (DAR) Measurement:

The dielectric absorption ratio is measured through the meter's automatic measurement function, which automatically measures the resistance at 1 minute and 30 seconds respectively. Pass/Fail is automatically displayed at the two time points.

  

Note: 

 

Not suitable for testing live components; power must be cut off and the components fully discharged before measurement.

 

Features:

 

ES300 High-Voltage Insulation Resistance Tester.

500V to 5000V Adjustable Test Voltage

Multi-Function Electrical Testing

Professional EV High-Voltage Insulation Testing

Reliable Insulation Risk Detection

 

Advantages:

 

1. When testing the insulation resistance of capacitive loads, the charge stored in the circuit loop is automatically released after the test is completed, and the voltage display can be used to check the discharge status.

 

2. Backlight function helps with operation in dim places or at night.

 

3. Circuit warning symbol and audible warning.

 

4. Circuit Detection Function: When the voltage exceeds 30V, the user is reminded to stop the insulation test.

 

5. Auto power-off (after 20 minutes of no operation) and battery check function.

 

6. Timed Measurement Function: automatically performs measurement at the set time.
