there are 4 slot locations and each slot location has 2 channels, thus there are 
8  channels  in  total  and  the  channel  number  ranges  from  right  to  left  in 
sequence. if each slot has one channel, then the channel number from right to 
left  should  be:1
th
  channel,3
th 
channel,5
th
  channel….For  module  with  dual 
channels,  the  channel  number  should  be:1th  and  2th  channels,3th  and  4
th
 
channels,5
th
  and  6
th
  channels….IT8703  extended  mainframe  can  be 
understood in the same way. 
The technical parameters of each module such as voltage, current and power 
are  different.  Refer  to  Chapter5  Specifications  for  more  details.  The  menu 
functions  of  module  IT8731/IT8732/IT8732B/IT8733/IT8733B/IT8731P/ 
IT8732P/IT8732BP/IT8733P/IT8733BP/IT8722/IT8723/IT8722B/IT8722P/IT87
23P/IT8722BP are similar. The difference between the 16 load modules is: the 
input  terminals  of  the  IT8731/IT8732/IT8732B/IT8733/IT8733B/IT8722/ 
IT8723/IT8722B are on the rear panel of the instrument; the input terminals of 
the  IT8731P/IT8732P/IT8732BP/IT8733P/IT8733BP/IT8722P/IT8723P/ 
IT8722BP are available on  the front  and rear panels of  the  instrument.  The 
main functions are described as follows:   
Module Features 
⚫  Working functions: constant current(CC),constant resistance(CR),constant 
voltage(CV),constant power(CW). 
⚫  Enable you to set the rising slope and falling slope of current in dynamic 
mode, dynamic functions has one mode: CC. 
⚫  Dynamic mode: up to 25KHZ. 
⚫  Voltage  measuring  resolution:0.1mV,  Current  measuring  resolution 
0.01mA(10 uA), measuring speed could reach 50KHZ. 
⚫  With remote sense function. 
⚫  Short-circuit function. 
⚫  Storage capacity:101 sets, used to save customer’s setting parameters. 
⚫  List mode: enable you to edit a list file in CC mode. Number of list steps: 
2-84, each step time: 0.000020~3600s.You can save seven list files. 
⚫  Auto test function, up to 10 test files or 100 test items. 
2.3 Front Pannel Introduction 
There’re  two  parts  in  front  panel,  which  are  main  panel  and  module panel. 
Refer  to  figure  2-1.  Main  panel  and  module  panel  keys’  function  will  be 
introduced below.
