STORE Readings 

The meter can store up to 100 pH and 100 mV readings for a total of 200 data points. To 
store a reading, wait until the reading stabilizes (the smiling face icon 

 appears when the 

reading stabilizes). Press the 

M+/RM

 key momentarily to store a reading. The 

M+

 icon 

appears and the data point serial number increments. 

RECALL Readings 

In the measurement mode, press the
