Barometer
This parameter allows configuration of parameters related to barometric pressure. This parameter is
only needed when measuring in concentration units of mg/L or ppm.
From the Barometer menu the user can choose the pressure source and units, as well as the pressure.
To access a
Barometer
option:
• Press
while in
DO
mode.
• Press

located inside the meter.
To set the
pressure source
:
• Select
or
using virtual key.
• Press
to return to previous menu.
Note: If Manual pressure source is chosen, the pressure
value used to compute is set manually. If Automatic
pressure source is chosen, the meter uses a measure-
ment from the pressure sensor located in the meter. This
sensor can be calibrated (see Pressure Calibration).
Pressure
Use to set Manual pressure value or calibrate the interrnal
pressure sensor used when Automatic is selected under
Pressure Source.
Note: Select Pressure unit first (see on the next page).
To set the
pressure
