5.9.3.11. ANALOG INPUTS (XIN1…XIN8) OPTION CONFIGURATION
To configure the analyzer’s external analog inputs option, define for each channel:
 gain (number of units represented by 1 volt)
 offset
(volts)
 engineering units to be represented in volts (each press of the touchscreen button scrolls the
list of alphanumeric characters from A-Z and 0-9)
 whether to display the channel in the Test functions
To access and adjust settings for the external Analog Inputs option channels press:

5.9.4. ELECTRICAL TEST
The electrical test function creates a current, which substitutes the PMT signal, and
feeds it into the preamplifier board. This signal is generated by circuitry on the pre-
amplifier board itself and tests the filtering and amplification functions of that assembly
along with the A/D converter on the motherboard. It does not test the PMT itself. (See
also Section
12.5.7.2).
