2. Safety Information

Always observe the following safety precautions to prevent electric shock, injury, or damage to the meter:

• Ensure the meter is in good working condition before use.
• Do not use the meter if it appears damaged or if the test leads are compromised.
• Always set the function switch to the appropriate range before connecting the test leads to the circuit under test.
• Do not exceed the maximum input values for each range.
• Be cautious when working with voltages above 30V AC RMS, 42V peak, or 60V DC, as these pose a shock hazard.
• Replace batteries and fuses only with the specified type and rating.
• Keep fingers behind the finger guards on the test probes during measurements.
• Disconnect the test leads from the circuit before changing functions or ranges.

3. Product Overview

5. Setup

5.1. Battery Installation

1. Ensure the multimeter is turned OFF.
2. Locate the battery compartment cover on the back of the meter.
3. Open the cover and insert two R6 (IEC) or UM-3 (1.5V) batteries, observing the correct polarity (+/-).
4. Close the battery compartment cover securely.

5.2. Connecting Test Leads

1. Insert the red test lead into the positive (+) jack.
2. Insert the black test lead into the negative (-) or COM jack.
3. Ensure the connections are firm.

6. Operating Instructions

The SANWA YX-360TRF operates with a manual range selection. Always select the appropriate function and range before making a measurement.

6.1. DC Voltage (DCV) Measurement

1. Set the function switch to the desired DCV range (e.g., 0.25V, 2.5V, 10V, 50V, 250V, 1000V). Start with the highest range if the voltage is unknown.
2. Connect the red test lead to the positive side of the circuit and the black test lead to the negative side.
3. Read the voltage value from the DCV scale on the display.

6.2. AC Voltage (ACV) Measurement

1. Set the function switch to the desired ACV range (e.g., 10V, 50V, 250V, 750V). Start with the highest range if the voltage is unknown.
2. Connect the test leads across the AC voltage source.
3. Read the voltage value from the ACV scale on the display.

6.3. DC Current (DCA) Measurement

1. Set the function switch to the desired DCA range (e.g., 50µA, 2.5mA, 25mA, 0.25A).
2. Important: The circuit must be broken to measure current. Connect the multimeter in series with the circuit.
3. Connect the red test lead to the higher potential side and the black test lead to the lower potential side.
4. Read the current value from the DCA scale.

6.4. Resistance Measurement

1. Ensure the circuit under test is completely de-energized.
2. Set the function switch to the desired Resistance range (e.g., X1, X10, X100, X1k, X100k).
3. Short the test leads together and adjust the ΩADJ knob until the pointer reads zero.
4. Connect the test leads across the component to be measured.
5. Read the resistance value from the Ω scale and multiply by the range multiplier (e.g., X1, X10).

6.5. Capacitance Measurement

The meter supports capacitance measurement up to 10µF. Refer to the specific scale and instructions on the meter face for accurate readings, noting that pointer indication reflects the maximum movement by charged current in the capacitor.

6.6. dB Measurement

The meter can measure dB values from -10dB to +22dB (for 10VAC) up to +62dB. Use the appropriate ACV range and read from the dB scale.

6.7. hFE Measurement

hFE measurement (transistor gain) is available at the X10 range, with an optional probe "HFE-6T" necessary for this function.

7. Maintenance

7.1. Cleaning

Wipe the meter with a dry, soft cloth. Do not use abrasives or solvents.

7.2. Battery Replacement

When the meter's pointer becomes sluggish or inaccurate, it's time to replace the batteries. Follow the steps in Section 5.1. Always use two R6 (IEC) or UM-3 (1.5V) batteries.

7.3. Fuse Replacement

If the current measurement function stops working, the fuse may be blown. Replace it with a φ5.2 x 20mm (250V/0.5A) fuse. Refer to the meter's internal diagram for fuse location, typically accessible by opening the back cover.

8. Troubleshooting

• No reading/Pointer not moving: Check battery charge, ensure test leads are properly connected, verify function and range selection, check for blown fuse (for current measurements).
• Inaccurate readings: Ensure proper range selection, perform ΩADJ for resistance measurements, check battery level.
• Meter appears damaged: Discontinue use immediately and contact support.

9. User Tips

• Verify Authenticity: While the product is branded Sanwa, its origin is Mainland China. If you have specific requirements for 'Made in Japan' products, please verify product details carefully before purchase.
• Start High, Go Low: When measuring unknown voltages or currents, always start with the highest range setting to prevent damage to the meter, then gradually decrease the range for a more precise reading.
• Zero Ohm Adjustment: For accurate resistance measurements, always perform the zero ohm adjustment by shorting the probes and turning the ΩADJ knob before testing.
