The operation of this command is determined, in part, by the firmware revision of
the Counter.
Current Firmware Revision
Sets or queries the size of the hysteresis window as a percentage of the allowable
hysteresis. For example, 0% is the minimum hysteresis setting and 100% is the
maximum hysteresis setting.
Specifying 100% or MAXimum provides the greatest noise immunity (lowest
sensitivity), while specifying 0% or MINimum provides the least noise immunity
(most sensitive).
Prior Firmware Revisions: 3317, 3335, and 3402
Sets or queries the sensitivity of the input channel as a percentage of the allowable
sensitivity. For example, 0% is the minimum sensitivity setting and 100% is the
maximum sensitivity setting.
Specifying 100% or MAXimum provides the most sensitivity
(least noise immunity), while specifying 0% or MINimum provides the lowest
sensitivity (greatest noise immunity).
