FID:
-ACCEPTED-
The ACCEPTED message appears for a short time and is then replaced by
the normal CALIBRATION menu.
When the ACCEPTED message disappears and the CALIB MENU
appears, the ZERO reference value is stored. This value is stored in non-
volatile memory until the next calibration is performed. The date and time
of this calibration are stored and can be accessed through the INFO menu.
Note For optimum accuracy, re-zero the FID every time the hydrogen
supply is turned on.
To set the span reference point, execute the procedure described below.
Note that the procedure is the same as that for setting the zero reference
Point(s)
except that a span gas is used instead of a zero gas. The procedure is:
1. From the CALIB MENU display, press 2=Span.
Note The following sequence shows the procedure when the TVA2020 is
configured with both Cal mode and Cal Save mode = Auto. If either mode
is Manual, an extra confirmation is required at the appropriate step.
Note If your instrument is a dual detector type (PID and FID), you can set
the span reference for the PID and FID separately, both together, or one in
one type of calibration gas and one in another type of gas. To do so, follow
the same procedure.
Note The FID and PID span concentrations must be the same for both
span reference point selections, otherwise an error screen will be
displayed.
Note If multiple span points are used, repeat the following procedure for
each and every span point.
