ERROR 

DESCRIPTION 

 

 

 

Low battery indicator “

LobAt” 

will show on the 

LCD before the meter goes off.  This indicates 
that battery power is low and that the batteries 
need to be replaced. 

Or 

 

“Over-range” when reading >20 pH, >2000 mV, 
or >99900 Ion 

Ur 

 

“Under-range” when reading <-2 pH or <-2000 
mV 

CAL 
Error

 

Calibration error appears if reading is not within 
the allowable pH buffer calibration range. 

SLOPE 
Error

 

Appears if the electrode slope is not within the 
acceptable range.
