E6240 User Manual
AKS – Adjacent Key Suppression can be enabled or disabled. To become active, a key with this
option enabled must receive the strongest signal relative to other AKS-enabled keys.
Scope Sync – sends a positive pulse that brackets the burst of a selected key. This feature is
invaluable for diagnostics.
WH – Wake allows the device to be configured to wake up when specific keys are touched. Each
key has its own configuration bit so that any combination of keys can be configured for this
purpose.

Mains Sync – allows the part to synchronise on the low frequency signal. This is generally used to
synchronise acquisition on the mains cycle (50/60Hz). The frequency must be more than 10Hz.
Sleep Duration – defines the length of time the device will sleep before automatically waking up
and returning to sleep.
Awake Timeout – defines the minimum amount of time the part will stay awake after a
communication or after a valid key press woke it up.
Drift Hold – defines the time the drift on the reference is held after a key is touched. This affects all
the keys. If set to Off all keys drift regardless of the state of other keys.
