What routines are required to complete a hard calibration on my Hardy PLC module?

On my Hardy PLC module, what routines are required to complete a hard calibration after cal low and cal high? Is WriteParams and/or Write NV Memory necessary so that the calibration won't be lost if power is cycled?

On a Hardy PLC module (which includes the HI 1746WS, HI 1756WS, HI 1756-2WS, HI 1756-FC, HI 1756-nDF, HI 1769WS, HI 1769-2WS, HI 1769-FC, HI 1771WS and the HI 200DNWM), writing the parameters will set up how the module will respond during operation.
The Calibration commands are used to insure the weights will be correct.
The Write to Non-Volatile command will save any changes to the parameters and calibration to the non-volatile memory in the unit to prevent the module from loosing its settings after a power cycle.

The Write to Non-volatile memory routine should be run after any changes. If you do not perform a Write to Non-Volatile routine then you will lose any changes you make the next time the power cycles.
