Data Logging
The data logging function provides the convenience of recording test data for
future review or analysis. Since data is stored in nonvolatile memory, the data
remains saved even if the multimeter is turned OFF or the battery is changed.
The two options offered are manual (hand) logging and interval (time) logging
functions, which is determined in the Setup mode.
Data logging records the values on the primary display only.
Manual logging
Firstly, ensure that manual (hand) logging is specified in Setup mode.
1 Press for more than 1 second to store the present value and function
on the primary display to the non-volatile memory. The and the logging
index will be indicated. The logging index flashes on the secondary display for
3 seconds before returning to normal display.
2 Press and hold again for the next value that you would like to save into
the memory.
NOTE
To use the data logging function, you will need to connect the multimeter to a
PC using the U1173A IR-to-USB cable (purchased separately) and download the
