Introduction
Model 480C02 & model 480E09 are rugged, portable, power sources for ICP ® sensors. These models are nearly
identical except model 480C02 is unity gain 1:1 only with no adjustment, while model 480E09 has the additional
feature of 3-position gain adjustment (1/10/100). They are powered internally by three replaceable batteries and
provide constant current excitation to the charge amplifier within ICP
®
sensors (or to in-line and adaptor style
amplifiers) and decouples the sensor output signal from the power. Signal output is a high quality, voltage output
compatible with standard readout, recording or acquisition instruments.
