7.1.2 Error checking

As data is entered into each field, error checking is performed when the
focus is moved from one field to the next. If appropriate, an error message
will occur indicating the nature of the mistake. At the same time, the
erroneous value is replaced with a default. To fix the error, accept the default
or move the cursor back to the previous field (press Shift-Tab) and enter the
correct value.
Error checking is based on hardware configuration limits determined by
the connected L-Series unit. There is one condition which is not checked
however. This is related to the high or low voltage range setting presently
active. Since transient registers can be programmed and saved for later use,
it is possible that the voltage values used in transient step are within limits if
the L-Series is in high voltage range. In low voltage range however, the same
transient parameters are invalid as they exceed to maximum voltage in the
low range. No check is made on the present range setting. Goto V and Final
V values are only limited by the high voltage range value reported by the L-
Series unit connected.
Consequently, if a transient register is downloaded that contains a voltage
value that exceeds the low voltage range limit and the unit is in the low
voltage range at the time, an error message will appear.
The offending register number is reported. To avoid this error, save the
transient data to a file or click on OK and use the steady state screen to
switch to high voltage range.
