Select Button

:  Touch sensitive button with LED touch indicator.  Press to scroll through data options or Smart Graph. 

3.

 

Enter Button

:  Touch sensitive button with LED touch indicator.  Press to return to the main screen.  If on the main 

screen, will scroll through set-up options. 

4.

 

Aux. Power

:  Female socket for device auxilliary power, 5.0Vdc +/-10%.  Compatable with USB mini-B Plug. 

5.

 

MicroSD Slot (Scientific Model Only)

:  Card slot for recording of measured values.  Can accept standard microSD 

flash memory formated with FAT32.  Metiri™

-S will automatically detect card, create a CVS file, and start writing 

measured data. 

6.

 

Source Wires

:  Connect to power source or battery up to +60Vdc.  Current flowing from Source to Load is considered 

positive current.  Forward continuous current should never exceed 50 amperes. 

7.

 

Load Wires

:  Connect to power load or battery up to +60Vdc.   Current flowing from Load to Source is considered 

negative current.  Negative continuous current should never exceed 50 amperes. 

8.

 

In Line Fuse (Sold Separately)

:  The Metiri™ products do not provide protection against 

excessive current.  A fuse 

installed in series with the positive Source Wire is required.  Current should never exceed the current specified in the 
Safe Operating Area graph.
