Yokogawa Electric Corporation YE 288171 FASF Analog Panel Meter

The Yokogawa YE 288171 FASF Analog Panel Meter is a high-sensitivity DC current meter designed to monitor very low current signals (0–1 mA DC) and scale the reading to a 0–500 VDC output using an external resistor. With a moving-coil (high-sensitivity) mechanism and an analog needle display, this panel-mounted instrument is built in an industrial-grade housing for precise, real-time indication of signal levels in control panels, laboratory instrumentation, power supplies, and precision measurement systems. It requires an external resistor for voltage scaling, making it suitable for legacy equipment and applications where accurate low-current monitoring is essential, such as replacement of microammeters and system calibration. Common replacements include Yokogawa 288171FAFA, Yokogawa 288173FASF, and Yokogawa 250 Series DC Microammeter.
