Changing the discharge data printout interval
Connect a terminal or computer to the nine pin D-
subminiature connector on the discharge unit. The
terminal format is set up to transmit at 1200 baud
with 8 bits, 1 stop bit, and no parity. The default
print routine for the discharge unit is to print data in
one minute intervals but only when the unit is on.
This can be changed to print data once a second by
pressing and releasing the DISPLAY button until
Func5 is displayed. Continue to hold in the
DISPLAY button while you press and release the
START/STOP button. This changes the value
displayed from 60 to a one. If you wish to change
the print routine back to the default setting, press
and release the DISPLAY button until Func5 is
displayed. Continue to hold in the DISPLAY button
while you press and release the START/STOP
button. This changes the value displayed from one
back to a 60.
The display format for the discharge data is the
following:
aaaaa bbbbb ccccc ddddd
where aaaaa = discharge time in minutes
bbbbb = discharge time in seconds
ccccc = present battery voltage
ddddd = lowest battery voltage during
discharge
