Extech Model 381676 is a multi-function pen multimeter with AC/DC voltage, resistance, diode and continuity testing plus a built-in non-contact Voltage Detector. Proper use and care of this meter will provide many years of reliable service.
The Extech Model 381676 is a pen-style multimeter designed for AC/DC voltage, resistance, diode, and continuity testing. It features a built-in non-contact voltage detector (NCV) capable of detecting AC voltages from 50 to 600VAC. The device includes retractable test leads and an LCD display with data hold and maximum hold functions.
| Input Limit | 250VDC or AC (200mV range); 600VDC or VAC (All other ranges) |
|---|---|
| NCV Detection Range | 50 to 600VAC |
| Continuity Threshold | Less than approximately 50 Ω |
| Good Diode Forward Voltage | 0.3V (germanium) to 0.7V (silicon) |
| Automatic Power Off | 15 minutes |
A shorted diode will indicate the same voltage value in both the reverse and forward test directions.
The meter automatically turns off after 15 minutes of inactivity to preserve battery energy.
