Default control = ON.
ISCALE?
Integer Scale Query. Returns the scale factor for
readings output in the SINT or DINT formats.
LEVEL [percentage][,coupling]
The LEVEL command specifies the level triggering
voltage (as a percentage of the present range)
and the coupling (AC or DC) for level triggering. A
level trigger event occurs when the input signal
reaches the specified voltage on its
positive-going or negative-going slope as
specified by the SLOPE command.
percentage: Specifies the percentage of the
present range for level triggering. The valid range
for this parameter is -500% to +500% in 5% steps
for direct or sub-sampling or -120% to 120% in
1% steps for DC voltage.
Power-on percentage = 0% (0V).
Default percentage = 0% (0V).
coupling = DC (1), AC (2)
Power-on coupling = AC.
Default coupling = AC.
LFILTER [control]
Level Filter. Enables or disables the level filter
function. When enabled. the level filter function
connects a single pole low-pass filter circuit to
the input of the level-detection circuitry. The
low-pass filter has a 3-dB point of 75 kHz and
