This spec sheet is applied to all of the PP01A chassis. 

(1) Because this is not a hot chassis, it is not necessary to use

an  isolation  transformer.  However,  the  use  of  isolation
transformer will help protect test instrument.

(2) Adjustment must be done in the correct order.
(3) The adjustment must be performed in the circumstance of

25±5°C of temperature and 65±10% of relative humidity if
there is no specific designation.

(4) The  input  voltage  of  the  receiver  must  keep  100~240V,

50/60Hz.

(5) The receiver must be operated for about 5 minutes prior to

the adjustment when module is in the circumstance of over
15°

- In case of keeping module is in the circumstance of 0°C,

it should be placed in the circumstance of above 15°C for
2 hours

- In case of keeping module is in the circumstance of below

-20°C,  it  should  be  placed  in  the  circumstance  of  above
15°C for 3 hours,.

This  is  for  downloading  the  s/w  to  the  flash  memory  of  the
IC402

(1) PC
(2) ISP_tool program
(3) Download jig

(1) IC name and circuit number : Flash Memory and IC402
(2) Use voltage : 3.3V (5 pin)
(3) SCL : 15 pin
(4) SDA : 12 pin
(5) Tact time : about 2min and 30seconds

1) Connect the download jig to D-sub jack

2) Connect the PC to USB jack

1) Execute ‘ISP Tool’ program in PC, then a main window will

be opened

2) Click the connect button and confirm “Dialog Box”.
