Analog Output
The analog output is a standard 15-pin D-sub connection that
allows analog signals to be read by an external instrument to
collect Electrospray voltage and current information. The pin
designations and signal connections are shown in Figure 3-3 and
Table 3-1, respectively. Note the conversion factors in Table 3-1.

AC Power Connector
The AC power connector accepts the line cord (supplied) to provide
AC power to the instrument. Line voltage can be 85 to 260 VAC,
50/60 Hz, single phase, 3A max. The connector has a built-in
on/off switch. Power consumption is 25 Watts, max.
Note
: Make certain the line cord is plugged into a grounded power
outlet. Position the Electrospray so the power cord connector is
easily accessible.
