IDLE MODE
During idle mode the device performs the same tasks as
when it is in control mode except for the relays. The alarm
relay is activated (no alarm condition), the acid and base
relays are not activated while the analog output remains
activated.
When the instrument is in idle mode the red and green
status LEDs are on.
Idle mode is useful to disable control actions when the
external devices are not installed or when the user detects
unusual circumstances.
Control actions are stopped as soon as
the user presses SETUP and enters the
password.
In order to reactivate the control mode, use code 02 of
setup (see “Setup” section). Otherwise, the meter remains
in idle mode.
