Extech 380395/380396 High Voltage Insulation Tester is a fully featured meter providing four insulation resistance test ranges plus Continuity, AC/DC Voltage, Polarization Index and Dielectric Absorption Ratio measurements.
The document provides a comprehensive User's Guide for the Extech Digital High Voltage Insulation Tester, specifically models 380395 and 380396. It details the instrument's features, including auto-ranging, selectable LCD backlight, MAX/MIN/PEAK functions, and specific safety standards compliance (IEC 61010-1 CAT IV 600V). The guide explains how to perform various measurements such as Insulation Resistance, Continuity, AC/DC Voltage, Polarization Index, and Dielectric Absorption Ratio.
| Insulation test range | 0.1MΩ to 60GΩ |
|---|---|
| Insulation test voltages | 500V, 1000V, 1500V, and 5000V |
| AC/DC voltage range | 0.5 V to 600 V |
| Continuity limit | 200mA |
| Resistance range | 0.1 Ω to 6kΩ |
| Power source | Eight (8) 1.5V 'C' Cell Batteries |
The meter offers four Insulation Resistance test ranges with voltages of 500V, 1000V, 1500V, and 5000V.
The PI Test calculates the ratio of the resistance measurement after 10 minutes to the resistance measurement after 1 minute.
Live circuit detection prevents the insulation test from running if a voltage > 30 V is detected.
