Overview
JB3126A Intelligent Insulation Resistance Tester Automatic Discharge Function: When testing the insulation resistance of capacitive loads, the charging charge is automatically released after measurement. The discharge state can be confirmed in voltage mode.
Product Details
JB3126A Intelligent Insulation Resistance Tester
characteristic
JB3126A Intelligent Insulation Resistance TesterisHigh voltage insulation resistance meter with a measuring range of 5 for measuring insulation resistance.
● Design in compliance with international safety standards:
IEC 61010-1, -2-030 (CAT III 600V/CAT IV 300V Pollution Level 2)
IEC 61010-031 (Requirements for Handheld Probes)
● Automatic discharge function: When testing the insulation resistance of capacitive loads, the charging charge is automatically released after measurement. The discharge state can be confirmed in voltage mode.
● The backlight function is convenient for working in low light or at night.
● A bar chart displays the measurement results.
● Warning signs and buzzing warnings for live lines.
● Automatic shutdown function: To avoid battery waste caused by forgetting to shut down, after measurementThe instrument will automatically shut down when there is no operation for 10 minutes.
● Automatic measurement andPI measurement (polarization index measurement), DAR measurement (induced absorption ratio measurement).
