Klein Tools CL390 is an automatically ranging true root mean squared (TRMS) digital clamp meter. It measures AC/DC current and NCVT via the clamp, AC/DC voltage, DC microamps, resistance, continuity, frequency, capacitance, and diodes via test leads, and temperature via a thermocouple probe. It features a high visibility, reverse contrast LCD display that optimizes view ability both in dark or bright ambient lighting.
- Test lead holder on side of clamp and optional magnetic hanger for meter (Cat. Nos. 69445 or 69417) for hands free operation
- Non-contact voltage tester integrated into the clamp jaw
- High-visibility reverse contrast LCD display for improved view ability in all ambient lighting conditions
- Automatically ranging True Root Mean Squared (TRMS) measurement technology for accuracy
- Measures AC/DC current and NCVT via clamp and AC/DC voltage, resistance, frequency, DC microamps, capacitance, duty cycle, diode test, and continuity via test-leads, and temperature with thermocouple
- Measures temperature with a K-Type thermocouple probe
