PerkinElmer Photovac 2020 Manual page 37

Introduction
2020 has many datalogging options. You can select an averaging
interval, or you can use manual operation. If you select an averaging
interval, the minimum, maximum, and average concentrations
measured in each period are automatically recorded in 2020's
datalogging memory. 2020 can log up to 1000 entries.
In manual operation, 2020 prompts you to locate a site and then to
record a background and sample readings for the site. You can
record up to 1000 manual entries. There is no averaging of data in
manual operation.
Recorded data can be reviewed on the display, sent to a printer in
either tabular or graphic al format, or sent to a computer. Data are
recorded by date and time.
2020 has 6 keys for alphanumeric entry and for accessing 2020's
functions. The keys are used to set up and calibrate 2020. They
allow you to manipulate the concentration data in various ways.
All information entered with the keys and stored in 2020's memory
is retained when the instrument is switched off. The clock and
calendar continue to operate and do not need to be set each time
2020 is turned on.
