5.5 Parameters
Operational parameters are controlled from the SETUP screens in the 3465 Detector. The
parameters are filter, cell potential, and offset. Temperature is set in the
CONFIG
menu.

5.5.1 Range
Range selection is done in the SETUP or STAT screen in DC, PULSE, and SCAN modes. A
number of ranges can be selected; the maximum current that can be compensated for using auto
zero and offset differs among ranges. The high sensitivity ranges (10 pA - 5 nA) have the best
noise specifications. In fact, there is a tradeoff between best noise specification at sensitive
ranges and maximum compensation at the less sensitive ranges. This is an inevitable
consequence of the tremendous dynamic range that is covered by electrochemical detection. The
information listed in the following tables is valid for 3465 Detectors with FW version 1.09 or
higher.
