Frequently Asked Questions (FAQ)
Q: Does this ammeter measure both AC and DC current?
A: The standard model is designed for alternating current (AC) measurement only. DC-specific digital ammeter models are available as separate products.
Q: What does 0.5 accuracy class mean?
A: Accuracy class 0.5 means the maximum permissible measurement error is ±0.5% of full scale, providing higher precision than traditional analog pointer meters (typically class 1.5).
Q: Can I use this meter with my existing current transformers?
A: Yes. The meter supports programmable CT ratio settings and works with all standard 5A secondary current transformers. You only need to set the corresponding primary current ratio through the front panel keys.
Q: What is the standard mounting hole size for this meter?
A: The standard panel cutout dimension is 92mm × 92mm, with an overall front bezel size of 96mm × 96mm, matching the universal 96-type panel meter standard.
