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 300 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.
To reset the min/max registers simply press the clear key. These registers are also cleared
at power-up or when the configuration is changed.
