pH/ 3400i Operation

4.5 Calibration intervals (Int 3, Int 4)

For each measured variable, a time interval is stored. When it has ex-

pired, you will be reminded to calibrate. After a calibration interval has

expired, the probe symbol of the relevant measured variable flashes. It

is still possible to measure. By calibrating the relevant probe, the func-

tion is reset and the interval starts anew.

The following calibration intervals are set in the factory:
