Technical Specifications:​ Input −10…+10 VDC differential; >9 kΩ load impedance; Class 1.5 accuracy (±1.5% FS); 24 VAC/DC backlight; 144×144 mm opening, 148×148 mm frame, ~65 mm deep, ~610 g; −10…+55 ℃; IP54 front, IP20 rear.

Functional Features:​ LED backlight with adjustable brightness; rear ADJ potentiometer for ±10% zero/full-scale trim; red/green partitioned scale; terminal insulation 2500 VAC 1 min.

Application Scenarios:​ Ship engine-room consoles; offshore platform panels; diesel-generator local cabinets; rudder-angle, pitch, RPM and valve-opening indication.

Performance Parameters:​ Class 1.5 accuracy; >9 kΩ input impedance; 2500 VAC terminal withstand.

Material Composition:​ Black flame-retardant ABS front shell; metal shielded back cover; analog movement with pointer mechanism.

Structural Characteristics:​ Square panel meter with A1/A2 signal and X1/X2 backlight terminals on the rear; shallow-depth embedded mount.

Working Principle:​ The differential analog input drives the pointer deflection directly; the backlight circuit is separately powered for visibility in dark cabins.

Installation Requirements:​ Cut a 144×144 mm DIN 43700 opening; match phase wiring for three-phase inputs; CT secondaries must never be open-circuited; use shielded RS-485 twisted pair with single-point ground and 120 Ω terminator.

Usage Precautions:​ No routine calibration needed; trim zero and span via the rear potentiometer; resistant to salt spray and oil mist but keep within −10…+55 ℃.
