Q: How to set the CT ratio and calibrate the digital ammeter, and what is the recommended calibration cycle?
A:
CT ratio can be set via front-panel buttons; calibration requires a standard current source or PC software (with RS485-to-USB adapter), following IEC procedures. The recommended cycle is 12-24 months.
Q: What international certifications does the digital ammeter have, and is it safe for global use?
A:
It holds CE, UL, and RoHS certifications, complying with IEC 61326-1 (EMC) and IP20 protection standards. It has overload protection (1.2x long-term, 10x short-term) and anti-interference design for harsh industrial conditions.
Q: Does the digital ammeter support standard output signals and communication protocols for system integration?
A:
Yes, it provides 4-20mA DC/0-10V DC standard analog output and optional Modbus RTU (RS485) communication, seamlessly compatible with Siemens, Schneider, ABB PLC/DCS systems.
Q: Does the digital ammeter support both AC and DC current measurement, and global power supply?
A:
Yes, it supports universal AC/DC measurement (e.g., AC 0-100A, DC 0-50A) and wide power supply (AC 85-265V/DC 24V), compatible with global industrial power systems.
Q: What current input ranges does the digital ammeter support, and do I need a current transformer (CT)?
A:
It supports direct input (AC/DC 0-5A) for small-current circuits and CT input (extensible to 0-1000A via 5A secondary CT) for large-current scenarios. The CT ratio (e.g., 50/5A, 200/5A) can be set via panel buttons, no need to replace the meter.

How to Implement Transformer Gap Protection & Standard Shutdown StepsHow to Implement Transformer Neutral Grounding Gap Protection Measures?In a certain power grid, when a single-phase ground fault occurs on a power supply line, both the transformer neutral grounding gap protection and the power supply line protection operate simultaneously, causing an outage of an otherwise healthy transformer. The main reason is that during a system single-phase ground fault, the zero-sequence overvoltage causes the transformer neutral grounding gap to break down. The resulting12/05/2025 -
