4.2.3 Rapid Resistance Change Detection/No Load Detection
Rapid Resistance Change detection/No Load detection (RRCd-NLDd) is used to
determine the instrument’s response due to a large change in resistance or the absence
of a load. See Section 3.1 for a description of how to set this parameter.
ON : Detection of sudden load changes or the absence of a load is enabled. Load
changes greater than 20% or 15 mA (whichever is greater), or the absence of a load
(current is less than 2 mA), will cause an alarm to sound, and the run to pause (see
Section 4.2.4 , ERROR STOP 01 and 09).
OFF : Detection of sudden load changes or the absence of a load is disabled. When
running in this mode, the symbol appears on the Run screen as a reminder that
this safety feature has been turned off.
NOTE: This mode is used to complete electrophoresis applications such as the D-Code
(requires that Rapid Resistance Change detection be turned off) or applications such
as isoelectric focusing (requires < 2 mA current).
