This selects the connection of the multimeter’s guarding. (For backwards compatibility
LCL & REM can also be used.)
For scan operations, the guard selection is applied to the channel currently being applied
to the A-D converter.

Measurement Gate Width
FAST_ON
Selects a gate width of 50ms, and a frequency resolution of 4.5 digits.
FAST_OFF
Selects a gate width of 1s, and a frequency resolution of 6.5 digits.
Both selections are mutually exclusive.
The use of the longer gate width results in a 6.5 digit frequency measurement. The
frequency gate is triggered at the same point as the A-D conversion which could be
significantly shorter than 1 second. This may reduce the read-rate, as the measurement
processing cannot begin until both the frequency gate and the A-D conversion are
complete.
Power On and Reset Conditions
FAST_ON.
