Frequently Asked Questions - CD772 Sanwa
How do I measure DC voltage with the Sanwa CD772?
Turn the rotary switch to the V symbol with straight and dashed lines. Insert the black lead into the COM jack and the red lead into the V/Ω jack. Connect the probes to the circuit and read the display.
How do I measure AC voltage?
Turn the rotary switch to the V~ position. Insert the black lead into COM and red lead into V/Ω. Connect probes to the source and read the RMS value on the display.
How do I test continuity?
Set the rotary switch to the continuity symbol (sound wave). Insert the leads as for resistance. Touch the probes together to verify the beep. Then touch the two points of the circuit. A beep indicates a closed circuit (< 50 Ω).
How do I measure resistance?
Turn the rotary switch to the Ω range. Insert the black lead into COM and red lead into V/Ω. Disconnect power from the circuit, then connect the probes across the resistor. Read the value.
How do I measure current?
For currents up to 600 mA, use the mA jack; for up to 10 A, use the 10A jack. Insert the black lead into COM. Set the rotary switch to the appropriate current range (A or mA). Break the circuit and connect the meter in series. Read the display.
What does the CAT rating mean?
CAT II and CAT III indicate the meter's safety for transient overvoltages. CAT II is for appliances and portable equipment; CAT III is for fixed installation (distribution boards). The CD772 is rated CAT II 600V and CAT III 300V.
How do I replace the batteries?
Turn off the meter and remove the test leads. Open the battery compartment on the back. Replace the two AA batteries (1.5V each), observing polarity. Close the compartment.
How do I replace the fuse?
The CD772 has a fused current input. If the meter shows no current reading, open the battery compartment and replace the blown fuse (typically 0.5A/600V or 10A/600V) with the same type.
Can I measure temperature?
Yes, the CD772 comes with a thermocouple. Set the rotary switch to the temperature mode (°C/°F). Insert the thermocouple into the dedicated jack or adapter. Touch the probe to the object and read the temperature.
What does the data hold button do?
Pressing the DATA HOLD button freezes the current reading on the display. This is useful for capturing measurements in hard-to-see locations. Press it again to release the hold.
