RANGE?
Returns the present measurement range parameters.
Response
1. (Float) The nominal maximum value for the range (uprange point in auto
range).
2. (Float) Minimum value measurable by range (not including low end
hysteresis for autoranging).
3. (Float) Resolution of range
4. (Integer) 1 if autoranging, 0 if range locked.
REF?
Returns the reference value and its associated parameters.
Parameter
None
Responses:
1. (Float) The reference value.
2. (Float) The frequency of the reference. (If references at two different
frequencies were averaged, the second frequency is returned.)
3. (Integer) The number of readings used to generate the reference value.
0 = reference off, 1 = reference set, 2 = reference averaged.
4. (CRD) The input connector at which the last reference was measured, for
example, INPUT1, or NONE if no reference is set.
REFAVG
Sets the reference to the average of the present stored reference value and the
present input measurement. This command generates an error if there is no
reference set or if the reference has already been averaged.
Parameter
None
REFCLR
Clears the reference.
Parameter
None
REFSET
Sets the reference to the value of the present input measurement. This
generates an error if a reference is already set. (Use REFCLR first in that case.)
Parameter
