2) Start / Stop data-logging

The meter supports multi-session data-logging.  Multiple 

functions can be logged one-at-a-time into the meter free 
memory up to 999 separate session-pages without erasing 
the formerly logged one(s). Press the           

(Start)

 button 

for  1  second  or  more  to  start  the  data-logging  mode.   

“LEFt”

 displays momentarily followed by a number (mini / 

main  displays  for  most-significant  /  least-significant 
numbers separately) to indicate the memory points left for 
new logging session(s).  Below example illustrates  43102 
memory points  is availbale for new logging session(s).

 

 Press the 

Yes

 button momentarily to confirm starting a 

   new logging session directly without erasing the 
   formerly logged one(s).

 Or you can press the 

Erase

 button momentaily to erase 

    ALL

 of the formerly loged session- page(s), and start a 

    new logging session from the very first session-pare 
    (P.001) with maximum meter memory.

 The bar-graph turns to a swinging pointer when data-

    logging  mode is running.

 Press 

SELECT

 button momentarily to toggle the LCD 

display between measuring data and logged data item 
number (mini / main displays for most-significant / least-
significant numbers separately).

  Press             

(PAUS/CONT/STOP)

 button momentarily 

to pause/continue logging.

  Press             

(PAUS/CONT/STOP)

 button for 1 second 

or more  to stope logging.

When a sampling speed of 30s or longer is selected, the 

meter will enter a 50% power down mode 
between data logging measurements (approx. 
4.2 minutes after data logging is started) 
displaying only the swinging pointer.  Press the 

SELECT

 button momentarily can resume real 

time display.
