3. Setup
3.1. Battery Installation
The INFURIDER YF-36K multimeter requires a 9V (6F22) battery for operation. A battery is included in the package.
- Ensure the multimeter is turned OFF.
- Locate the battery compartment cover on the back of the device.
- Use a screwdriver to open the battery compartment.
- Insert the 9V battery, observing the correct polarity (+ and -).
- Replace the battery compartment cover and secure it with the screw.
3.2. Test Lead Connection
Connect the test leads to the appropriate input jacks on the multimeter based on the measurement you intend to perform:
- The black test lead (negative) should always be connected to the COM (Common) jack.
- For voltage, resistance, capacitance, frequency, diode, and continuity measurements, connect the red test lead (positive) to the VΩmA Hz jack.
- For current measurements up to 400mA, connect the red test lead to the VΩmA Hz jack.
- For high current measurements (up to 10A), connect the red test lead to the 10A jack.
4. Operating Instructions
The INFURIDER YF-36K is an auto-ranging multimeter, simplifying operation by automatically selecting the correct measurement range.
4.1. Power On/Off
- To turn on the multimeter, rotate the rotary switch from the "OFF" position to any desired measurement function.
- To turn off the multimeter, rotate the rotary switch to the "OFF" position.
- The device features an auto power-off function after 15 minutes of inactivity to conserve battery life.
4.2. Backlight and Data Hold
- Press the HOLD button briefly to activate the Data Hold function, freezing the current reading on the display. Press again to release.
- Press and hold the HOLD button for over 2 seconds to turn the backlight ON/OFF. This is useful in dimly lit environments.

4.3. Measuring AC/DC Voltage
- Connect the black test lead to the COM jack and the red test lead to the VΩmA Hz jack.
- Rotate the rotary switch to the V~ (AC Voltage) or V- (DC Voltage) position.
- Touch the test probes to the circuit or component you wish to measure.
- Read the voltage value on the LCD display.

4.4. Measuring AC/DC Current
- Connect the black test lead to the COM jack.
- For current up to 400mA, connect the red test lead to the VΩmA Hz jack. For current up to 10A, connect the red test lead to the 10A jack.
- Rotate the rotary switch to the A~ (AC Current) or A- (DC Current) position.
- Open the circuit where you want to measure current and connect the multimeter in series with the circuit.
- Read the current value on the LCD display.
4.5. Measuring Resistance (Ω)
- Connect the black test lead to the COM jack and the red test lead to the VΩmA Hz jack.
- Rotate the rotary switch to the Ω (Resistance) position.
- Ensure the circuit or component is de-energized before measuring resistance.
- Touch the test probes across the component.
- Read the resistance value on the LCD display.

4.6. Measuring Capacitance (Cap)
- Connect the black test lead to the COM jack and the red test lead to the VΩmA Hz jack.
- Rotate the rotary switch to the Cap position.
- Discharge any capacitors before testing to prevent damage to the multimeter.
- Touch the test probes across the capacitor.
- Read the capacitance value on the LCD display.
4.7. Measuring Temperature (Temp)
- Connect the temperature probe to the COM and VΩmA Hz jacks, observing polarity.
- Rotate the rotary switch to the Temp position (usually °C/°F).
- Place the tip of the temperature probe on or near the object whose temperature you want to measure.
- Read the temperature value on the LCD display.

4.8. Diode and Continuity Test
- Connect the black test lead to the COM jack and the red test lead to the VΩmA Hz jack.
- Rotate the rotary switch to the Diode/Continuity position.
- For diode test: Touch the probes across the diode. A forward voltage drop will be displayed. Reverse the probes; an "OL" (Overload) reading indicates a good diode.
- For continuity test: Touch the probes across the circuit or component. A continuous beep indicates continuity (low resistance).
5. Safety Information
The INFURIDER YF-36K Digital Multimeter is designed with safety in mind, adhering to IEC 1010, CAT III 600V, and CE standards. It includes overload protection on all ranges for secure and reliable operation.

|---|---|---|
| No display or dim display | Low battery or no battery installed. | Replace the 9V battery. |
| "OL" (Overload) displayed | Measurement exceeds the selected range or maximum input. | Select a higher range or ensure input is within device limits. |
| Incorrect readings | Incorrect function/range selected, poor test lead contact, or damaged leads. | Verify function/range, ensure good contact, check/replace test leads. |
| Multimeter turns off unexpectedly | Auto power-off activated due to inactivity. | Turn the multimeter back on. This is a normal power-saving feature. |
