Switching on the measuring instrument

1 Connect the D. O. probe to the measuring instrument.
2 Press the <ON/OFF> key.
The display test appears briefly on the display.
The relative slope for the sensor type that was just connected
subsequently appears for approx. one second.
The measuring instrument then automatically switches to the
measuring mode that was last selected. The display shows the
relevant measured value.
Note
The Oxi 315i handheld oxygen meter automatically recognizes the type
of D.O. sensor that is connected (CellOx 325 or
DurOx 325).
Warning
Only connect sensors to the measuring instrument that cannot return
any voltages or currents that are not allowed (> SELV and > current cir-
cuit with current limiting). Almost all sensors - in particular WTW sen-
sors - fulfill these conditions.
