C. Reading hold
The reading hold feature is used to hold a stable reading on the display. When a reading
is stable, enabling the reading hold will hold the stable reading and trigger a beeping
sound. Reading hold feature depends on an adjustable sensitivity band to determine if a
reading is stable. The multimeter considers a reading stable when three consecutive
readings are within the sensitivity band. Chapter 3.4.4 will explain how to adjust the
sensitivity band.
How to use reading hold
This feature is only available from the front panel operations. To enable reading hold,
press both SHIFT and AUTO TRIGGER buttons. To disable it, simply press AUTO
TRIGGER. The locations of the buttons are shown with red rectangle frames in
Figure
4-12 .

D. Trigger delay
This feature is useful for user who needs a longer delay time to wait for the system to be
stabilized. The time needed to stabilize a measurement system is called the “settling
time.” The settling time depends on the measurement range, cable properties and signal
source.
Defaults
The default of the trigger delay is automatic. DL-2060 automatically selects a delay time
for you according to the setting of the measurement if you do not specify a delay. A list
of the default for each measurement function is shown on
Table 4-4 . The range for the
delay is from 0 to 3600 seconds. User's selection of delay time is stored in a volatile
memory and the default will be restored when the meter is power-off.
