7-6 Triggering Model 6485 Picoammeter Instruction Manual
Trigger delay
A programmable delay is available after event detection. It can be set manually (0 to
999.9998 seconds) or an auto delay can be used. With auto delay selected, the Model 6485
automatically sets delay according to range. The auto delay settings are listed in Table 7-1.
Measure action
The measure action block of the trigger model is where a measurement is performed.
However, if the repeating filter is enabled (see Figure 7-3), the instrument samples the
specified number of reading conversions to yield single filtered reading. Only one reading
conversion is performed if the digital filter is disabled, or after the specified number of
reading conversions for a moving average filter is reached.
