Thermo Fisher Scientific TVA2020 Instruction Manual 2-3
This analyzer functions in any of four modes:
●
RUN
●
SETUP
●
INFO
●
MEMORY
In the RUN mode, the instrument automatically displays its measured
values in units of ppm or %. The RUN mode may be operated either as
survey only, in which the instrument displays measured values but does not
store any data, or survey and log, in which the instrument displays
measured values and also stores the information in memory.
In SETUP mode, you can enter or select operational parameters, such as
calibration values, alarm levels, operator ID, datalogging method and
interval, date, and time. This may be performed locally by using the
analyzer keypad or remotely by using the USB connection to a personal
computer (PC).
In INFO mode, you can review operational parameters entered or selected
in SETUP mode as well as instrument serial number, Bluetooth friendly
name, battery status, GPS coordinates, etc.
In MEMORY mode, you can download data stored within the TVA2020
to a PC for analysis and printing, upload route list, calibration, and
configuration parameters from a PC to the TVA2020, clear data memory,
and update instrument firmware.
Each of the four modes is explained in detail later in Chapter 3, “ Display
Menus ”.
