GENERAL OPERA

TIONS

Set the Alarm Low and Alarm High as boundaries of acceptable variation for pH. If these bound‑
aries are exceeded, the display flashes as a visual indication that the desired solution pH has 
changed. 

  

Use 

▲▼

keys to set pH alarm value.

Press the 

Accept

 key to confirm the value or 

Escape

 to return to the  general menu  without saving 

the new value. 

  Note: The high alarm must be set to a value greater than the low alarm.

Calibration Timeout

Calibration Timeout feature is used to set a calibration or service reminder. This can be configured 
from 1‑30 days or disabled. A message will be displayed with the measurement indicating it's time 
to service the probe. 

Resolution

Press functional key to choose desired pH resolution  
(0.01 or 0.1).
Press 

Escape

 to return to the general menu.
