[SENSe:]VOLTage[:DC]:RESolution
Syntax [SENSe:]VOLTage[:DC]:RESolution {<resolution>|MIN|MAX}[,(@<ch_list>)]
[SENSe:]VOLTage[:DC]:RESolution? [{(@<ch_list>)|MIN|MAX}]
Description
Set or query the resolution of the DCV measurements on the specified channels.
Parameters
Name
Type
Range
Default
<resolution> Numeric
Any numeric value between
0.03ppm×<range> and
3ppm×<range>. The final resolution is
decided by the “
Principle of setting with
smaller value
”.
The standard values of the resolution:
refer to the “Explanation”.
0.3ppm×
<range>
<ch_list>
Channel
List
One or more channels (only for the
multiplexer channels), the rules are as
follows:
(@101): channel 01 on the module in
Slot1;
(@101:103): channel 01 through 03 on
the module in Slot1;
(@101:103,301): channel 01 through 03
on the module in Slot1 and channel 01 on
the module in Slot3.
If the parameter
is omitted, this
command will be
applied to the
whole scan list.
Explanation  You can use MIN or MAX to set <resolution>. Wherein, MIN selects the smallest
resolution; MAX selects the largest resolution.
 <resolution> is related to the current integration time and range (<range>). The
relations are as shown in the table below.
Integration time
Resolution (ppm range)
0.02PLC
3ppm× <range> (MAX)
0.2PLC
0.7ppm× <range>
1PLC
0.3ppm× <range> (DEF)
2PLC
0.2ppm× <range>
10PLC
0.1ppm× <range>
20PLC
0.06ppm× <range>
100PLC
0.035ppm× <range>
200PLC
0.03ppm× <range> (MIN)
 When the range is set to autoranging, an error will be generated when <resolution> is
set to a numeric value (except MIN and MAX).
 The instrument sets the resolution to 0.3ppm× <range> after a Factory Reset (send
the
*RST command). An Instrument Preset (send the SYSTem:PRESet command) or
Card Reset (send the SYSTem:CPON command) does not affect the current resolution.
Return
Format
The query returns the resolution in scientific notation for each channel specified. Multiple
return values are separated by commas.
Example VOLT:DC:RANG 300,(@201:203)
VOLT:DC:RES 0.006,(@201:203)
VOLT:DC:RES? (@201:203)
The query returns +9.00000000E-04,+9.00000000E-04,+9.00000000E-04.
