FAQ
Q1. Does this meter require an external CT for current measurement?
No. It has a built-in 30A CT for direct current input up to 30.0A AC.
Q2. Can it show voltage and current at the same time?
Yes, it has separate LED displays for ampere and volt, both visible simultaneously.
Q3. What is the supported voltage range?
It measures 30–500V AC, suitable for standard single-phase applications.
Q4. Are there functional differences between AV-12, AV-22, and AV-33?
No. Functions are identical; only panel size and cutout differ to suit various panel layouts.
Q5. Is it suitable for 230V AC control panels?
Yes, it supports 100–270V AC/DC auxiliary and measures 230V AC within the 30–500V range.
Q6. Can it be used in humid industrial environments?
Yes, it operates up to 95% RH (non-condensing); with the optional IP65 front, it is suitable for typical industrial panel rooms.
