Frequently Asked Questions - PDR302 Sanwa
How do I measure DC voltage?
Set the rotary switch to DCV, connect the red lead to the VΩmA jack and the black lead to COM, then touch the probes to the circuit. Read the value on the LCD.
How do I use the continuity buzzer?
Turn the dial to the continuity position, insert the leads, and touch the probes together. The buzzer sounds if the resistance is below about 50Ω.
What does the battery symbol mean?
It indicates low battery. Replace the batteries promptly to avoid incorrect measurements.
How to replace the batteries?
Remove the battery cover, replace both AAA batteries with new ones, ensuring correct polarity, and close the cover.
Can I measure AC voltage safely?
Yes, but never exceed 500V. Ensure the function switch is at ACV and the leads are correctly inserted. Use insulated gloves in live circuits.
Why does the display show "1"?
This indicates overrange. Select a higher range or check the input level. The input is beyond the selected measuring range.
How do I measure resistance?
Switch to Ω mode, connect the resistor to the test leads, and read the value. For in-circuit resistance, disconnect power and discharge capacitors first.
How should I clean the device?
Wipe the case with a soft, dry cloth. Do not use solvents or abrasive cleaners. Keep the input jacks clean.
What are the safety precautions?
Never use the meter on circuits above CAT II 500V, don't measure with wet hands, and always check the leads for damage before use.
How do I store the meter?
Turn off the meter, remove the batteries if not in use for long periods, and store in a dry, cool place.
