Maximizing Measurement Speed
This program shows the multimeter configuration required to make
measurements at the fastest possible rate (13150 readings/sec).
10 !Dimension a computer array to store the readings.
20 DIM Rdgs(1:500)
30 !
Clear and reset the multimeter. For mainframes with a display and
40 !keyboard, turn off monitor mode so the measurements are not displayed.
50 CLEAR 70903
60 OUTPUT 70903;"*RST"
70 OUTPUT 70903;"DISP:MON OFF"
80 !
Configure the multimeter for DC voltage measurements. Increase
90 !measurement speed by specifying a fixed range (7.27), the worst
100 !resolution (MAX), and turning autozero off. Specify the number of
110 !readings in the burst and set the fastest sample rate. Store the
120 !readings in mainframe memory.

Comments
• The 13 kHz reading rate is achieved under the following conditions:
function = DC voltage
range = fixed
resolution = least
aperture time
= 10
µ
s
autozero = off
sample rate
= 76 µs (MINimum)
reading storage = mainframe (or shared) memory
In addition, there should be no activity by other instruments in the
mainframe.
