Frequently Asked Questions - KEW3431 Kyoritsu
How do I measure AC voltage with the Kyoritsu KEW3431?
Turn the dial to the AC voltage (V~) setting. Connect the black test lead to the COM jack and the red lead to the V jack. Touch the probes to the circuit and read the display. The meter is auto-ranging.
What type of batteries does the KEW3431 use?
The KEW3431 uses two AAA 1.5V batteries. Replace them when the battery indicator shows low, using the same type.
How do I perform a continuity test?
Set the dial to the continuity/ohm symbol ( ). Connect the leads to COM and V. Touch the probes together to confirm the beep, then test the circuit. A beep indicates continuity (< 50 ohms).
What is the maximum voltage the KEW3431 can measure?
The KEW3431 can measure up to 600V AC or DC. Do not exceed this limit to avoid damage or injury.
How do I replace the batteries?
Turn off the meter and remove the test leads. Unscrew the battery cover on the back, remove old batteries, insert two new AAA batteries observing polarity, then replace the cover and screws.
What does the data hold function do?
Press the 'HOLD' button to freeze the current reading on the display. Press again to release. This is useful for recording measurements when you cannot view the display directly.
How do I measure resistance?
Set the dial to the ohm (Ω) setting. Disconnect power from the circuit. Connect the leads to COM and V. Touch the probes across the resistor and read the value.
What safety rating does the KEW3431 have?
The meter is rated CAT III up to 600V. This means it is suitable for measuring on distribution circuits. Always use caution with high voltages.
Can I measure current with the KEW3431?
Yes, but only up to 10A AC/DC. Use the 10A jack for high current measurements. For lower ranges, use the mA/uA jacks if available. Note: direct current measurement is limited to 10A for up to 30 seconds.
How do I clean and maintain the KEW3431?
Wipe the meter with a damp cloth and mild soap if needed. Never use abrasives or solvents. Keep it dry and store in a case. Check test leads for damage before use.
