Frequently Asked Questions - KEW 2055 Kyoritsu

How do I measure AC current with the KEW 2055?

Set the Function Switch to the 600A or 1000A position. Ensure AC is selected (default). Press the trigger to open the jaws, clamp onto a single conductor, and read the display. For frequency/duty, press the Hz/DUTY key. Note: The input must be ≥60A for AC 600A range or ≥350A for AC 1000A range to measure frequency.

How do I measure DC current?

Set the Function Switch to the 600A or 1000A position. If AC is selected, press SELECT to change to DC. With jaws closed, press ZERO to zero the display. Then clamp onto the conductor and read the value. The polarity is positive when current flows from the upper to lower side of the instrument.

How do I measure AC voltage?

Set the Function Switch to ACV. Connect the red test lead to the VΩ terminal and black to COM. Connect probes to the circuit and read the display. Press Hz/DUTY to measure frequency (requires ≥40V AC). Use the protective fingerguard (barrier) on the probes.

How do I measure DC voltage?

Set the Function Switch to DCV. Connect red test lead to VΩ and black to COM. Connect red to positive (+), black to negative (-) of the circuit. Reversed polarity shows a '-' sign. Keep fingers behind the protective fingerguard.

How do I measure resistance?

Set the Function Switch to the Ω/Cont/Diode position. Press SELECT until Ω is displayed. Connect test leads to the resistor. Short the tips to zero the display (if not zero, it's lead resistance). Open leads show 'OL'. Do not measure on energized circuits.

How do I test continuity?

Set the Function Switch to the Ω/Cont/Diode position. Press SELECT until the continuity symbol (buzzer) appears. Connect test leads; the buzzer sounds if resistance is below approx. 100 Ω. Keep fingers behind the barrier.

How do I test a diode?

Set the Function Switch to Ω/Cont/Diode position. Press SELECT until the diode symbol appears. Connect red lead to anode and black to cathode. The forward voltage (0-2V) is displayed. Reversed connection shows 'OL'. Some diodes (e.g., Zener, LED) may not be tested.

How does the NCV (Non-Contact Voltage) function work?

NCV automatically detects electric fields when voltage exceeds about 100V. The red LED on the upper panel lights up. The sensor is on the fixed element (left side) of the jaws; keep that side close to the conductor. It cannot detect voltage behind walls or outlets. Always verify functionality on a known source before use.

How do I replace the batteries?

Set the Function Switch to OFF. Unscrew and remove the battery compartment cover on the bottom. Replace with two new R03 (AAA) batteries, observing correct polarity. Replace the cover and tighten screws. Do not mix old and new batteries.

What safety precautions should I follow?

Never measure on circuits exceeding AC/DC 600V. Do not use in the presence of flammable gases. Keep fingers behind the protective fingerguard. Use appropriate personal protective equipment. Verify operation on a known source before use. Do not open the battery cover during measurement. Follow all WARNING and CAUTION instructions in the manual.

Therefore, the OCR result must ignore it and output nothing or only meaningful text. The provided OCR content is "____", which consists of four underscores. This is an incorrect interpretation of the line as a placeholder, violating the rule that stylistic lines must be ignored. The OCR has hallucinated placeholder underscores where none exist in the GT.
