Operation 4–34
Figure 4-49 Two Term Percentage Limits screen
The Term soft key is used to toggle between Term 1 and Term 2 in order to set their limits.
LL1 and HL1 can be set when Term 1 is active. LL2 and HL2 can be set when Term 2 is
active. The active Term is identified by a box around the parameter.
The Abs/Perc soft key (Absolute/Percentage) is used to toggle between setting the limits as
either Absolute limits or Percentage limits. For Two Term limits only, it is possible to have one
Term as absolute limits and the other Term as percentage.
The High Limit soft key is used to enter HL1 and HL2 limits. After pressing the High Limit
soft key, enter the required value using the numerical key pad. After entering the first digit for
Absolute Limits, the soft keys will change and offer a variety of multiplier units (as a short cut)
for the parameter being set. For example, when the active Term is C(apacitance), the soft keys
will display pF, nF, uF and mF. Alternative the full numerical value can be entered and then
confirmed by pressing the Enter key.
For example, a limit of 1µF can be entered as either 1 uF or 0 . 0 0 0 0 0 1 Enter.
The Low Limit soft key is used to enter LL1 and LL2 limits. These are set in the same way as
the High Limits described above.
The Nom (Nominal) soft key is only displayed when the Abs/Perc soft key is toggled to Perc.
It is used to enter the nominal value which the percentage limits are calculated from. After
pressing the Nom soft key, the nominal value can be entered in the same way as High Limits
and Low Limits. It is also possible to save the last measurement as the Nominal Value. This
can be done by pressing the Save Res(ult) soft key which appears after pressing the Nom soft
key. When absolute limits are selected, the word “Nom” is still shown on the screen, but is not
used.
