Setting the Resolution The aperture time is set as a result of specifying the <resolution> parameter
in the
MEASure or CONFigure command, or by directly setting it with the
VOLTage:APERture or RESistance:APERture command.
Table 4-5 on page 92 can be used to pick a value for the
<resolution>
parameter in a MEASure or CONFigure command when you want to set the
aperture time. Select the range and aperture, and then look up the resolution
from the table. Round the resolution up to one less significant digit and use
it in the
CONFigure or MEASure command.
A less complicated method used to set the aperture time is to specify it
directly. This requires that you use the
VOLTage:APERture command.
For example:
10 OUTPUT @Dmm;"CONF:VOLT:DC (@100:103);:VOLT:APER 100e-6;:READ?"
20 ENTER @Dmm;Dc_readings(*)
Temperature
Measurements
Thermocouple temperature measurements are actually a computation
following both a voltage and a resistance measurement. Thermistor or RTD
temperature measurements are actually a computation following a resistance
measurement. To change the aperture for temperature, you need to change
the
RESistance:APERture for thermistor measurements and the
RESistance:APERture and VOLTage:APERture for thermocouple
measurements. For example:
10 OUTPUT 70903;"CONF:TEMP TC,J,(@100:115)"
20 OUTPUT 70903;"VOLT:APER MIN;:RES:APER MIN"
30 OUTPUT 70903;"READ?"
40 ENTER 70903;Reading(*)
