Refresh Hold
The refresh hold operation allows you to capture and hold a reading,
within specified variation and threshold values. This is useful in situations
when you need to know if the running values of a setup is stable or not.
This is done by comparing the running values to the initial hold value. A
preset variation count will determine the range of values that is
considered stable in reference to the initial hold value. You can set the
variation count through the setup menu. Refer to
Hold/Refresh Hold mode," starting on page 70 on how to set the variation
count.
When a stable reading is first detected, the instrument beeps once (if the
beeper is enabled), and holds the reading (the initial hold value) on the
primary display. The instrument will then compare the running values to
the hold value to check if the variation value exceeds the set variation
count.
A new reading value will be updated in the primary display when the
variation of the measured value exceeds the variation count preset in the
setup menu. The instrument beeps once (if the beeper is enabled) when a
reading value is updated.
For voltage, current, and capacitance measurements, the reading value will
not be updated when the reading falls below the threshold preset in the
setup menu.
For continuity and diode tests, the reading value will not be updated
when an open state is detected.

updated until the measuring value is stable.
