10. Minimum and Maximum Storage Capability
The HPC600 has 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.
11. Leak Test
The calibrator features a leak test function which calculates leak rate. The
timer can be set from 5 to 120 seconds, regardless of the set time the leak
rate is calculated in leak per minute. The function gives a good and
repeatable expression for the leak of a pressure system. This feature might
be used before calibration to document / indicate leak rate.
To use the leak rate function proceed as follows:
