4.2.6 ERROR addition
Press the key. The LED in the key lights.
Select the error addition rate with the keys.
To add a single error, select the right of the LED
using the key. At this time, the LED does not go on.
The single error adds one error each time the key is
pressed. The LED blinks each time a error is added.
Error addition can be inserted for one, and only one, of the 32 routes by using the rotary switch on the rear panel (see
below). Therefore, the error multiplied by the output can be added to only one route of the output (1/8 OUTPUT ).
Example) When a 1 x 10 -4 error is added to one channel, following occurs:
1/8 OUTPUT: 1 10 -4 8 (= 8 10 -4 ) error is added to DATA1.
No error is added to DATA2 to DATA8.
The numbers in circles ( ) indicate the output order for 1/8 DATA OUT.
From the above drawing, in 1/8 OUTPUT, if the error insertion channel is 1, 9, 17, or 25, the error is inserted into 1/8
DATAOUT. If the error insertion channel is 5, 13, 21, or 29, the error is inserted into 1/8 DATAOUT 5.
Notes : 1. When the rotary switch is set to channel 00, an error is added to channel 1.
When the rotary switch is set to channel 33 to 99, an error is added to channel 32.
2. When the FUNCTION switch on the rear of the instrument is set for external error injection, the error
addition amount cannot be changed. However, the error addition ON/OFF key is enabled.
