REDUCED (TWO-LINE) PRINTOUT 

This section describes the reduced printout which is available by sending the KATC-C1 the reduced 
printout command from a computer. This command is described in a preceding section. The purpose 
of  the  command  is  to  minimize  time  required  to  obtain  test  result  data  from  the  KATC-C1.  No 
heading information or descriptive wording is included in this printout.

Notes:  When the TUT Test Current Switch is set to 1 ampere, the decimal point for the TUT TEST 

CURRENT (AMPS) printout is shifted one digit to the left (X.XXX). 

The entry shown for transformer-under-test ratio error will vary depending on whether Ratio 
Error  (shown  above)  or  Ratio  Correction  Factor  (X.XXXXX)  is  selected  on  the  KATC-C1 
front panel.
