7. Again, use the arrows to set 0% point and select DONE SET when
finished and the %ERROR mode will be ready to use.
Note: The 0% and 100% point will be saved in non-volatile memory
until they are changed again by the user for the internal sensors, and
external pressure modules. When using an external module the 0%
and 100% are set to low and full scale of the module until the user
changes it, or if it was previously saved.
9. Minimum and Maximum Storage Capability
The CONDEC 3030 Series Pressure Calibrators have a min/max
feature for capturing the minimum and maximum values of any
displayed parameter.
The min/max function can be accessed by stepping through the
menu options until "min/max" is shown on the display above the F1
key. At this time, pressing the F1 key will toggle the display through
the min/max values that are stored in the min/max registers. These
readings are live so that the new min/max values will be recorded
while in this mode.
