Data Acquisition Mode 

In the data acquisition mode, the meter is connected to the computer while taking readings. 
At the same time the readings are taken, they are displayed and stored on the computer. The 
readings can be displayed as a List, a Voltage graph or a Resistance graph. 
 
 
 
 
 
 
 
 
 
 
 
 
 

Sampling Rate Setting for Data Acquisition Mode 

The sampling rate for the data acquisition 
mode can be set from 1 reading per 
second to 1 reading every 86,400 
seconds (1 sample every 24 hours).  
 
Note: This sampling rate setting is for the 
data acquisition mode only. For 
datalogger mode, the sample rate is set 
using the meter’s front panel controls as explained earlier in this manual.
