CAUTION
GENERAL SAFETY HAZARD
The T803 analyzer can be configured for both 100-130 V and 210-240 V at either
47 or 63 Hz.
To avoid damage to your analyzer, make sure that the AC power voltage
matches the voltage indicated on the Analyzer’s serial number label tag (See
Figure 3-4) before plugging the T803 into line power.
3.3.1.2. ANALOG INPUTS (OPTION 64) CONNECTIONS
The Analog In connector is used for connecting external voltage signals from
other instrumentation (such as meteorological instruments) and for logging these
signals in the analyzer’s internal DAS. The input voltage range for each analog
input is 0-10 VDC, and the input impedance is nominally 20kΩ in parallel with
0.1µF.
