Martel Electronics 235 - Manual (Page 48)

After the trip occurs, the input display shows:
To restart the ramp and reset the trip condition, press either the INC or
DEC key once to reset the ramp to the starting or ending value and
reset the tripped indication. Press the INC or DEC key a second time to
start the ramp. Be sure to reset the external trip circuit if necessary
before starting the ramp.
Min-Max Mode
The calibrator continuously stores the minimum and maximum values
of the input readings. The min-max function allows these values to be
displayed at any time.
To use the function, select the input variable to be displayed and press
the INC key to display the minimum and maximum values recorded.
The minimum and maximum values will be displayed until any key is
pressed. Pressing any key will reset the min and max values to the
most recent reading and the calibrator will return to displaying real
time values. The minimum and maximum values are reset each time an
input function is selected or re-selected.
Input Reading in Percent of Scale
This feature allows the input measurements to be displayed as a
percent of scale rather than in engineering units. This allows error
calculations in percent to be quickly calculated.
The feature is accessed through the Setup option InpRdg, and is
normally utilized with output Calibration Points which are also
programmed in percent of scale.
