The transferred data comprises 14-byte ASCII codes. The numbers 0
~
9 can be
expressed as ASCII codes 30H
~
39H. For example, 8 can be expressed as 38H, the
decimal point is expressed as 2EH, V is expressed as 56H, and A is expressed as 41H.
For example, if the transferred measurement results are 30H, 2EH, 31H, 32H, 33H,
34H, 56H, 35H, 2EH, 36H, 37H, 38H, 39H, 30H, 41H, the result should be
0.1234V5.67890A.

Working state of the instrument
U
:
5.0000
:
1.02500/
The instrument enters into CV working state. The voltage is 5V and the limit
value for current is 1.025A. Then the instrument will transfer the 16-digit
measurement result to PC. The received data is set mistakenly so that the
instrument can
’
t reach CV state after self-adjustment. Then, it will transfer
“
F(46H)
”
to PC.
I
:
21.0200
:
3.00000/
The instrument enters into CC working state. The current is 3A and the limit
value for voltage is 21.02V. Then the instrument will transfer the 16-digit
measurement result to PC. The received data is set mistakenly so that the
instrument can
’
t reach CC state after self-adjustment. Then, it will transfer
