The Instantaneous Menu
The TOGGLE FLG soft-key in this menu allows the user to set the CAL DATA FLAG value ON or OFF, which marks the
data with an M flag to indicate a maintenance was performed during that time, such as a flow check. This feature is
rarely used, as most maintenance requires stopping the sample anyway. The VOLT / ENG soft-key toggles the
displayed values between units and voltages, useful for diagnostic checks on external sensors.
3.13 The AVERAGE Screen
The AVERAGE screen is similar to the INST screen, except that the concentration and flow are presented as the
previous hour’s average values, and the six external datalogger channels are average values over the average period
of the data logger (set by the MET SAMPLE value in the SETUP > SAMPLE menu - usually also 60 minutes).
