Operation 

Power 

1.

 

Install six (6) ‘AAA’ 1.5V batteries in the meter. The batteries provide backup power for the 
clock. 

2.

 

Connect the AC/DC power adaptor to the DC 9V input on the meter. The power adaptor is 
required for data logging. 

3.

 

When the  

 icon appears in the display the batteries are weak and should be replaced. 

However, in-spec. measurements may still be made for several hours, after the low battery 
indicator appears.

Connect the current loop to the plug as shown and then 

insert 

the plug into the sockets on the bottom of the datalogger 
(observe correct polarity).  

2.

 

Up to three cables may be installed.  

3.

 

The current for the inserted cables will be displayed 1, 2, 

and 3 

from top to bottom.

Datalogging 

1.

 

Open the left side door and insert a formatted SD card 

Notes: 

 

The SD card should be 1GB to 4GB in capacity. 

 

Do not use memory cards formatted by other meters or cameras. Use the SD card 
formatting procedure under the advanced features section of this manual to correctly 
format the card. 

 

The internal clock must be set to the correct time. See the advanced features section of 
this manual to set the clock. 

 

The default data structure uses a decimal point “.” as the numeric decimal indicator. See 
the advanced features section of this manual to change this to a comma “,”. 

 

If the SD memory card is not installed, “EMPTY” will appear in the display. 

 

If the current cable is not installed, random numbers may appear in the data file. 

 

If the current cable is not installed, after data download the units symbol may not appear 
in the display.
