Save (Save setup values in non-volatile RAM)
This function allows the setup parameters that have been entered to be
saved in non-volatile RAM. If the Setup mode is exited without saving
(by pressing the SETUP key a second time), the setup parameters
remain temporary in nature and will only be retained until the
instrument is powered off.
The SAVE option will allow the setup parameters to be retained, even
with power off, until they are changed by the operator.
InpRdg (Input Readings displayed as percent of scale)
This option allows you to configure the active input function to display
in percent of scale, rather than the standard engineering units. The
calibrator will prompt for the value of zero percent.
Enter the value in engineering units that represents the 0% value. Next
the calibrator will prompt for the value for 100 percent.
Enter the value in engineering units that represents the 100% value.
The input function will now be configured to display in percent of scale
rather than engineering units. The input functions will return to
displaying in engineering when the next input function is selected.
Damp (Dampen input readings)
This feature allows noisy input signals to be electronically dampened
for easier reading. When the feature is enabled, a running average is
displayed, rather than the instantaneous value.
