REL Relative control
CHANNEL
Syntax:
REL <c>,<mode>
c:
1 or 2
mode:
0 Turn OFF
1 Turn ON and reference
2 Turn ON, use old references if not first time.
Remarks:
Turns relative ON or OFF, or references the zero point.
REL1 and REL2 toggle between relative and absolute measurements.
Sending the RELx command when in dB mode will make the meter apply
the last used RELATIVE value. This relative value is used thereafter until it
is replaced by another one in the same manner. This allows the user to re
-
fer to a previously referenced value, without the meter resetting itself back
to a 0.00 display.
