1.8 Repeat Runs
Each detection modality has the option to do repeat runs. Injectors cannot be used in this mode.
In repeat runs, the entire sample plate is read between each period.
1.8.1 Repeat Runs Parameters
Readings: The number of times a sample plate is read. When the number of readings is
set to a value between 2 and 99, the period parameter and time estimates are displayed.
The time estimate for a plate (located below the readings parameter) is based on the
number of wells selected to read.
Period: The time difference between readings of the same well. If this value is less than
the time estimated to read the plate, a caution message will appear to inform user the
actual interval will be longer. The instrument will begin reading A1 (or the first well
selected) immediately after completing the last reading of the plate. The actual period
time is indicated on the results .csv file when exported to a computer. The range is 1 to
120 minutes in 1-minute increments.
1.8.2 Viewing Repeat Runs Data on the RESULTS Screen
The results are displayed as a set of data on the RESULTS screen. To view the other sets of
data, touch the PLUS button to move forward and touch the MINUS button to move back. All data
from repeat runs are saved in one results file. The Modulus™ Microplate Reader saves all
captured data to its internal memory. However, when the FILES button is touched, only 50 of the
most recent files are visibly listed. To view results files not displayed, touch the USB button to
transfer all the files to a USB flash drive and view them on a PC or Mac.
