Multimeter Features 3
Capturing Maximum and Minimum Values (MaxMin)
U1273A/U1273AX User’s Guide 93
3 The elapsed time is shown on the secondary display.
Press to restart the recording session.
4 Press or for more than 1 second to disable the
MaxMin function.
This mode is useful for capturing intermittent readings,
recording minimum and maximum readings unattended, or
recording readings while equipment operation keeps you
from observing the multimeter display.
The true average value displayed is the arithmetic mean of
all readings taken since the start of recording. The average
reading is useful for smoothing out unstable inputs,
calculating power consumption, or estimating the percentage
of time a circuit is active.

NOTE
• Changing the range manually will also restart the recording session.
• You can also use the MaxMin function while measuring frequency (see
“Measuring Frequency” on page 81). If the measured frequency shown
is not reflected accurately, press again to restart the recording
session.
• If an overload is recorded, the averanging function will be stopped. OL
is shown in place of the average value.
• The APO (auto power-off) function is disabled when MaxMin is
enabled.
• The maximum recording time is 99999 seconds (1 day, 3 hours, 46
minutes, 39 seconds). OL is shown if the recording exceeds the
maximum time.
