Frequently Asked Questions - KEW 8133 Kyoritsu
How do I measure AC current with the KEW 8133?
Set the rotary switch to the appropriate AC current range. Open the clamp jaws and place the conductor inside. The measured value is displayed on the LCD. For accurate readings, ensure the conductor is centered in the jaw.
Can this clamp meter measure DC current?
Yes, the KEW 8133 can measure DC current. Select the DC current mode, perform zero adjustment if necessary, and clamp around the conductor. The reading will be displayed with polarity.
What is the maximum voltage measurement this device can handle?
The KEW 8133 is designed to measure up to 600 V AC/DC. It complies with CAT III 600 V safety standards. For higher voltages, a different instrument is required.
How do I replace the battery?
Turn off the device and remove it. Locate the battery compartment at the back, unscrew the cover, and replace the 9V battery. Reattach the cover and tighten.
What does the HOLD button do?
The HOLD button freezes the current displayed reading, making it easier to record measurements in difficult positions. Press HOLD to capture the reading and press again to release.
Why does the display show OL?
The OL (overload) indication means the input exceeds the measurement range of the meter. This is not a malfunction; switch to a higher range if available, or stop measuring to protect the device.
How should I clean and maintain the clamp meter?
Wipe the device with a soft dry cloth to remove dust or dirt. Never use harsh chemicals, solvents, or water. Keep the jaws free of debris for accurate measurements.
How often should calibration be performed?
For accurate and reliable measurements, it is recommended to calibrate the instrument annually at an authorized Kyoritsu service center. Environmental conditions may require more frequent calibration.
