Continuity Test
If the resistance is below approximately 50O:
- The built-in buzzer will sound continuously.
- A red LED indicator will light up.
- This indicates a complete path (good continuity).
If the circuit is open (broken) or resistance is high (e.g., > 4000O):
- The buzzer will not sound.
- The LED will not light.
- The display will show "OL" (Over-Limit).
Auto Power Off Function
- The meter will automatically power down approximately 15 minutes after the last button press or function change.
- A visual indicator (such as an "Auto Power Off" icon or countdown) may appear on the LCD shortly before shutdown to alert the user.
Note
This function is triggered by a lack of user interaction. Any button press or change in the measurement function will reset the timer.
Protective Case for Multimeter
- Impact & Scratch Protection:The durable housing helps absorb shocks and prevents scratches on the LCD display and housing.
- Moisture & Damp Proof:When closed, the case offers protection against dust and moisture.
Long-Lasting Battery
- The battery compartment is secured with a screw. To replace the batteries, you must first use a screwdriver to open the compartment cover.
- Important: Always disconnect all test leads before unscrewing the cover.
