Setting Oxygen When the Device Is in POLL-mode

To set oxygen value in POLL-mode, use the following addressable
command:

XO addr x

The device does not reply to the command. If given oxygen value is not
within limits, the command is rejected. The given value is written to
volatile memory, where it will be overwritten either by next XO-command
or O-command. At start the first compensation value is a value given by
O-command if it was saved by SAVE-command. Purpose of the XO-
command is continuous update of compensation value sent by another
measurement device.

Oxygen Compensation Mode

To enable or disable the oxygen compensation, use the commands:

OC x

SAVE

x=ON/OFF (default =ON)

>oc on

OC: ON

>save

NOTE

Check that the ambient pressure value is correct. The correct pressure
value is needed for oxygen compensation even if the pressure
compensation is disabled.
