Reading Hold Function

Start the Reading Hold Function, the hold measurement use the following rules

judge the reading count:

When Max() - Min() ≤ hold range x ReadingN, the multimeter hold ReadingN on the

display.

The display update a new reading basing on the current value and the three

preceding measurements before the reading was hold:

Max (ReadingN, ReadingN-1, ReadingN-2, ReadingN-3)

Min (ReadingN, ReadingN-1, ReadingN-2, ReadingN-3)

NOTE

Reading Hold is stored in nonvolatile memory. The default is 0.1%.

When Reading Hold started, the input resistance was set to 10MΩ for all DC voltage

range to reduce noise arising from the open-loop testing.
