6. Set the non-constant Use the soft keys to select a non-constant
parameter limits for parameter and the keypad to enter its value.
the current step If the method is complete skip to Step 9,
otherwise, press the EDIT key. Note: to
change the constant value, press its soft key
and enter a new value.
ConstV:
Used to change the voltage
constant value.
LimitA: Used to change the current limit
value.
LimitW: Used to change the power limit
value.
7. Select the time mode Use the soft keys to select a time mode and
the keypad to enter the run time. Press the
EDIT key.
HRS:
Run time is in units of hours.
VHOURS: Run time is in units of volt-hours.
UNTIMED: Run is continuous. Note that steps
programmed after an un-timed
step are ignored.
8. Add a new step or If more steps are to be added to the method,
save the method use the down arrow key to move to the empty
