Can the KEW5050 measure capacitance?
Yes, select the capacitance mode using the rotary switch. Connect the test leads to the capacitor. The meter can measure from 10 nF to 4000 μF. Discharge the capacitor before testing.
How do I use the temperature function?
Set the switch to °C/°F. Insert the K-type thermocouple into the input terminals. Touch the probe to the measurement surface. The display shows temperature. The meter supports a wide range of -50°C to 1000°C.
What is the data logging capability?
The KEW5050 can log up to 60,000 data points when paired with the Kyoritsu app via Bluetooth. You can record measurements over time, generate reports, and export data for analysis.
How do I set the auto power off?
The meter automatically turns off after 15 minutes of inactivity to save battery. To disable auto power off, press the Auto Off button during startup. The symbol will disappear from the display.
What does the 'OL' reading mean?
