Audible Signals

The meter will beep under certain conditions:

•

a non-functional key press is made (one beep)

•

when display lock is enabled and measurement stability is 
reached during reading mode (three beeps)

•

any time measurement stability is reached during calibration 
mode, regardless of the Display Lock setting

•

to signal an error condition (two beeps)

•

if the number entry and a press of the 

ENTER

 key causes two 

beeps, the meter will automatically return to the beginning of 
number entry.

31

Indicates the displayed number is the electrode slope.

32

Indicates Time is being set or displayed.

33

When on or flashing, 

Stabilizing...

 indicates signal from sample is not yet stable. When it 

disappears, the reading is stable.

34

Indicates meter is in recall mode and the data displayed is stored data.

35 (CAL)

Indicates meter is in Calibration mode. If the 

?

 is flashing, calibration is necessary.
