Familiarize Yourself with the Controls: Take some time to understand the function of each button, switch, and dial on the multimeter. Refer to the user manual for detailed explanations.
Safety First: Always follow safety precautions when working with electricity. Wear appropriate personal protective equipment (PPE), such as safety glasses and insulated gloves. Never work on live circuits unless you are qualified to do so.
Basic Measurements: Start by practicing basic measurements, such as measuring the voltage of a battery or the resistance of a resistor. This will help you get a feel for how the multimeter works.

Step-by-Step Guide to Common Measurements

Let's walk through some common measurements you'll likely perform with your KEW 1018:

Measuring AC Voltage

Turn the rotary switch to the AC voltage (V~) range.
Insert the black test lead into the COM (common) terminal and the red test lead into the V terminal.
Connect the test leads to the AC voltage source you want to measure. Ensure the probes are making good contact.
Read the voltage value displayed on the screen. Note the unit of measurement (e.g., volts).

Measuring DC Voltage

Turn the rotary switch to the DC voltage (V-) range.
Insert the black test lead into the COM terminal and the red test lead into the V terminal.
Connect the test leads to the DC voltage source, ensuring correct polarity (red to positive, black to negative).
Read the voltage value displayed on the screen.

Measuring Resistance

Turn the rotary switch to the resistance (Ω) range.
Insert the black test lead into the COM terminal and the red test lead into the Ω terminal.
Connect the test leads to the resistor you want to measure. Make sure the circuit is de-energized.
Read the resistance value displayed on the screen. Note the unit of measurement (e.g., ohms, kilohms).

Measuring AC Current

Turn the rotary switch to the AC current (A~) range.
Insert the black test lead into the COM terminal and the red test lead into the A terminal (or mA terminal for smaller currents).
Break the circuit and connect the test leads in series with the circuit. Ensure you are within the meter's current range.
Read the current value displayed on the screen.

Measuring DC Current

Turn the rotary switch to the DC current (A-) range.
Insert the black test lead into the COM terminal and the red test lead into the A terminal (or mA terminal for smaller currents).
Break the circuit and connect the test leads in series with the circuit, observing correct polarity.
Read the current value displayed on the screen.

Advanced Features and Tips

Alright, now that you've mastered the basics, let's explore some advanced features and tips to enhance your experience with the Kyoritsu KEW 1018:

Using the Data Hold Function: When measuring values in hard-to-reach areas, press the HOLD button to freeze the displayed reading. This allows you to remove the test leads and read the value comfortably.
Utilizing the Min/Max Recording: The MIN/MAX function is great for capturing intermittent voltage spikes or drops. Press the MIN/MAX button to start recording, and the meter will track the minimum and maximum values. Press the button again to cycle through the MIN, MAX, and current readings.
Understanding Auto-Ranging: The auto-ranging feature simplifies measurements by automatically selecting the appropriate range. However, you can also manually select the range if you prefer more control or if the auto-ranging is not providing accurate readings.
Temperature Measurement: If your KEW 1018 comes with a temperature probe, you can measure temperature by connecting the probe and selecting the temperature range. This is useful for HVAC maintenance and other applications where temperature monitoring is important.
Continuity Testing: Use the continuity test function to quickly check for broken wires or poor connections. The meter will emit an audible beep when continuity is detected.

Maintaining Your Kyoritsu KEW 1018

To ensure your Kyoritsu KEW 1018 lasts for years, proper maintenance is essential. Here are some tips to keep it in top condition:
