To select, set the cursor under the currently selected field and use the Up
or Down arrow key to toggle between Hrs and Vhrs. Move the cursor to the
desired digit location using the Right and Left arrow keys, and change the
value using the Up and Down arrow keys.
The original factory programmed time for each step is 0:00, and should be
set to 0:00 for all unused steps. The Vhrs value is calculated according to
the explanatory note at the left, but these values can be set in the same
manner as the Hrs values.
Note:
When toggling from Hrs to Vhr, the value in the Vhrs field is automatically
calculated according to the selected voltage change pattern:
For Step-n-hold, Vhr is the product of hours and voltage.
For Gradient, Vhr is the product of hours and the mean of the voltage limit
set for the current step and the previous step.
Absolute Vhr limits can be set to any value from 1 to 30000 Vhr.
