16.2.3 Dual Measurement Mode Commands
VDC2
Sets the secondary display to dc Volts (autoranging).
VAC2
Sets the secondary display to ac Volts (autoranging).
IDC2
<CPD>
Sets the secondary display to dc Amps and optionally selects mA
(autoranging) or the 10A range; if no range is specified the existing range is
used.
The following <CPD> can be used:
<1MA>,<100MA>,<1000MA>,<10A>
If the main display is set to ac Amps the secondary range will be the same
as the main display range.
IAC2
<CPD>
Sets the secondary display to ac Amps and optionally selects mA
(autoranging) or the 10A range; if no range is specified the existing range is
used.
The following <CPD> can be used:
<1MA>,<100MA>,<1000MA>,<10A>
If the main display is set to dc Amps the secondary range will be the same
as the main display range.
FREQ2
Sets the secondary display to frequency (autoranging). VAC or IAC must
first have been selected in the main display.
16.2.4 First Level Modifier Commands
NULL
Nulls the main display and sets it to manual, i.e. the current range is held.
The un-nulled reading will be shown in the secondary display if the meter is
not in dual measurement mode, except for capacitance.
NULLOFF
Cancels Null operation.
HOLD
Holds the value in the main display. The normal, updated, reading will be
shown in the secondary display if the meter is not in dual measurement
mode, except for capacitance.
HOLD OFF
Cancels Hold mode.
DB
<CPD>
Sets the main display to show the dB value of the Vac measurement (which
must have first been selected in the main display) and optionally sets the
reference impedance; if no impedance is specified the existing value is
used.
The following <CPD> can be used to set the impedance:
<50>,<75>,<93>,<110>
,<124>,<125>,<135>,<150>,<250>,<300>,<500>,<6
00>
,<800>,<900>,<1000>,<1200>,<8000>.
DBOFF
Cancels DB mode.
