Depending on the duration the switch is held, a short “TAP” or long “HOLD” will be detected:
To carry out a tap function, tap the relevant switch location for 1 second, until a single
“chirp” is heard, remove wand to confirm a “TAP.”
To carry out a hold function, do not remove the magnetic wand after the first chirp but
continue to hold for >5 seconds
, until a double “chirp” is heard, remove wand to confirm
a “HOLD.”
If either switch is held for >30s, a stuck switch fault will be indicated.
To interact with the instrument without use of the magnetic wand, two internal push button
tactile switches may be used. Remove lid without removing ribbon cable to access. Internal
switches TACT#1 and TACT#2 mirror the functions of MAG#1 and MAG#2.
The function of each switch depends on the current state of the instrument as indicated in the
following table:
