Frequently Asked Questions - KEW 8343 Kyoritsu
How do I measure AC voltage with the KEW 8343?
Set the rotary switch to the AC voltage position (V~). Insert the black lead into the COM terminal and the red lead into the VΩ terminal. Touch the probes across the load or power source. Read the value on the display. Ensure the circuit is de-energized before connecting to avoid sparks.
What is the maximum voltage the KEW 8343 can measure?
The KEW 8343 can measure up to 1000 V DC and 750 V AC between the input terminals and earth. For safety, do not exceed these limits and always comply with the CAT III or CAT IV ratings.
Can the KEW 8343 measure temperature?
Yes, the KEW 8343 supports temperature measurement using a type K thermocouple (not included). Select the °C/°F function on the rotary switch, connect the thermocouple to the dedicated input, and place the probe on the object.
How do I replace the batteries?
Turn off the meter and remove the test leads. Unscrew the battery compartment cover on the back. Replace the four AAA batteries, ensuring correct polarity. Close the cover and tighten the screws. Dispose of old batteries properly.
What is the accuracy of the KEW 8343?
The basic accuracy is ±0.5% for DC voltage and ±1.2% for AC voltage. Actual accuracy depends on the function and range, as stated in the user manual. For critical measurements, check the specifications table.
How do I perform a continuity test?
Set the rotary switch to the continuity beep position (usually marked with a diode and sound waves). Insert the leads, connect them to the test points. If the resistance is less than about 50 Ω, the built-in buzzer will sound, indicating a closed circuit.
Is the KEW 8343 safe for industrial use?
Yes, the KEW 8343 is designed for industrial environments and complies with IEC 61010-1. It has a CAT IV 600V rating for use at origin of installation and CAT III 1000V for distribution circuits. Always follow the safety instructions in the manual.
How often should I calibrate the meter?
To maintain accuracy, the KEW 8343 should be calibrated annually by a certified service center. Calibration is recommended after heavy use, impact damage, or if measurements seem erratic. Check the calibration sticker or contact Kyoritsu support.
Can I measure current above 10 A?
No, the KEW 8343 is rated for a maximum continuous current of 10 A. For currents above this, use a compatible clamp adapter or a dedicated clamp meter. Exceeding the limit may blow the fuse and damage the meter.
What do the symbols on the display mean?
Key symbols include DC voltage (V⎓), AC voltage (V~), low battery (battery icon), auto power off (APO), and hold (H). The display also shows the unit of measurement (V, A, Ω, Hz, etc.) and the range. Refer to the manual for a complete list.
