Sifam IS 11180 模拟电压表

"Performance based on BS6840:Part 17:1991 & IEC 268-17:1990, which cover dynamic characteristics, frequency response, harmonic distortion, input impedance and temperature range. Calibrated for use with a 3.6kΩ resistor 4VU above the scale marking so that reference deflection (0VU) is produced by a signal 4VU above 1mW in 600Ω (1.228V). Transparent acrylic front and polystyrene (SAN) rear body moulding with various bezels available separately. Taut band core magnet movement housed in a 26mm diameter barrel occupies minimum behind panel space. Rear zero adjustment screw. Connections via 6mm tag terminals (High Specification - M4 bolt terminals). Meters do not suffer from calibration interference when mounted on ferrous panels. Black ABS front and behind panel mounting bezels, supplied separately. Dual meter scale indicates -20 to 3dB and 0 to 100%. Rear mounting 12V bulb top-lighting assemblies are available for rear mounted meters. Operating temperature range â€\"25 to +55°C.
