FUNCTION
DESCRIPTION
For channel B, this fulfils a similar
function to unit A; it is presented
at the bottom of the display.
Pressing A-B obtains, at the bot-
tom of the display, the difference
between the value at input A and
the one at input B.
The measurement unit selected
for the two values must be the
same for both probes, otherwise
an ERR message is given.
The Serial Output key enables the
data being acquired to be sent
immediately onto the serial line.
The Serial Out symbol flashes.
Note:
The choice of the baud rate
influences the speed at which the
data are sent as shown in the
table:
