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.
