Frequently Asked Questions - DCM400AD Sanwa
How do I measure AC current with the DCM400AD?
Set the rotary switch to the AC current range (e.g., 400A). Clamp the jaw around a single conductor. Read the value on the LCD. Ensure the conductor is centered for accuracy.
What is the maximum voltage the DCM400AD can measure?
The DCM400AD can measure AC/DC voltage up to 600V. Do not exceed this rating to avoid damage or injury.
How do I test continuity with this meter?
Turn the dial to the continuity/Ω position. Connect the test leads to the circuit. If the resistance is below about 50Ω, the buzzer will sound.
What battery does the DCM400AD use?
It uses a standard 9V battery (type 6F22 or equivalent). To replace, remove the battery compartment screw and slide the cover off.
Can I measure DC current with this clamp meter?
The DCM400AD measures AC current only. For DC current, you would need a meter with DC clamp capability.
How do I use the Data Hold function?
Press the 'Data Hold' button while measuring. The current reading will freeze on the display. Press again to release.
What does CAT III 600V mean?
CAT III 600V is a safety rating indicating the meter can withstand transient surges up to 600V in distribution level installations. Suitable for measuring on circuits connected to the mains.
How should I clean the DCM400AD?
Use a soft, dry cloth to clean the housing and display. Do not use solvents or abrasive cleaners. Ensure the meter is turned off and leads disconnected.
Why does the display show 'OL'?
'OL' stands for Overload. The input exceeds the selected range. Switch to a higher range or check the measurement setup.
Can I replace the test leads?
Yes, if the test leads are damaged, replace them with identical leads rated for CAT III 600V or higher. Ensure proper connection to the meter.
