Data Storage Function (DML-430A only)
The DML-430A has data storage and retrieval capability. It can store up to 87,000 measurements in
single display mode or 43,000 measurements in dual display mode. The data can later be reviewed on
the multimeter's display, or downloaded the data to a computer using the optional interface DMSC-9U.
When in the recording mode, the meter takes a measurement, assigns that measurement to the next
available memory location, and repeats the process. This continues until the memory is full or until the
user manually stops the recording process.
The time interval between measurements (sampling rate) is selected by the user. A shorter time interval
will provide information about short-term fluctuations, whereas a longer time interval will provide
information about general trends. The factory setting is the shortest time interval.
The time intervals are as follows: 0.05 seconds (0.1s for single T1/T2, Diode, and Ohms/nS; 0.5s for
Hz and Duty Cycle; 2s for Capacitance and dual screen T1/T2 and T1-T2), 0.1s, 0.5s, 1s, 2s, 3s, 4s, 5s,
10s, 15s, 30s, 60s,120s (two minutes), 180s (three minutes), 300s (5 minutes), and 600s (10 minutes).
The minimum total measurement time for the DML-430A is 72 minutes and 30 seconds; the maximum
is nearly 20 months.
When the sampling rate is 30s or greater, the meter will go to standby mode between measurements
to extend battery life. When the meter is in the standby mode, press SELECT momentarily to view the
display.
To set the measurement interval:
Press
for 1 second or more and the meter will display the current measurement interval in seconds.
Press p or q to change the measurement interval. Press
setting.
To start recording data:
Press the
button for 1 second or more to start the data logging mode.
"LEFt" displays followed by the number of remaining memory in the logger. The number in the second-
ary display is the most significant digit, and the numbers in the primary display are the least significant
digits of the remaining memory points.
Momentarily press the Yes button to confirm a new logging session without erasing the formerly logged
ones (up to 999 sessions can be stored without overwriting previous sessions). Press the Erase button
momentarily to erase all of the sessions and start from the first session with full memory.
"Strt" will display on the primary screen and then the logger will start recording. When a sampling
speed of 30s or longer is selected, the meter will enter a power down mode after 4.5 minutes. Press
the SELECT button momentarily to resume real time display.
Options —during recording:
SELECT button momentarily to toggle the display mode between measuring data and
Press the
logged data item number. The secondary display contains the most significant number and the
primary display contains the least significant numbers of the logged data item number.
Press the
button momentarily to pause/resume logging.
