How to Use 

 

 

Cautions 

 

- No power switch is available for this instrument, therefore the instrument becomes its operation state 

when connected to a power source.   

- Connect to a power source only after completing the wiring. 

- Please be careful not to confuse the wiring. Incorrect wiring may result in instrument failure. 

- Do not touch the terminals while power is being supplied. 

- Please use the input load within the standard specifications. 

- Remove  all  electrical  wirings  before  moving  the  instrument.  Fail  to  do  so  may  cause  dropping  of  the 

instrument. 

- Make  sure  to  select  a  proper  type  of  AC  adaptor  in  accordance  with  related  standards  and  product 

specifications when not using the accessory device that comes with the instrument. 

- Make sure to put the terminal cover on during usage time in prevent from dust or an electric shock. 

- Input  a  direct  current  with  the  range  from  4  to  20  mA.  Using  the  instrument  outside  of  its  range  may 

cause instrument failure. 

 

1. AC adaptor 

Please select an adaptor which meets following specifications when using another adaptor that was not 

included in the instrument. 

 

<Primary output> 

Voltage 

: DC12V 

Electrical Current  : 1A 

Polarity 

Plug diameter 

: outer diameter ø5.35mm, inner diameter ø2.1mm, length 9.25mm 

 

2. How to use 

(1) Check for the correct wiring and secure fixture of the instrument. 

Refer  to  the  'Wiring  method'  and  'Installation  method'  sections  of  this  manual  for  proper  wiring  and 

secure installation. 

 

(2) Insert the AC adaptor plug into DC jack from 

the AC adaptor outlet. 

The  LED  on  the  display  will  light  up  and  the 

instrument is in operation. 

 

 

 

 

(3) In order to finish the operation, pull out the AC adaptor from DC jack. The display will turn off and the 

operation is ended.
