Description
Models 480C02 / 480E09 contain three, PP3 size, 9 volt batteries connected in series to provide DC power to
internal electronics which provide regulation for approximately 2.6 mA of constant current power. Connections
include two BNC jacks, one for Sensor (ICP
®
power/input) and one for Scope (output to scope, data recorder, or
DAQ). The front panel meter indicates the voltage output when connected to a sensor and is color coded for
various fault conditions, shown in Figure 1 & 2. Optional connections include sockets for EXT PWR and BATT
CHG. A central, three-position rocker switch allows off, on and momentary battery test functionality.
Model 480E09 has the additional 3-position gain adjustment that multiplies the signal output through the SCOPE
connection. It has 2 additional settings beyond the 480C02, 10x and 100x, shown in Figure 2.
