Reading Hold Function
Start the Reading Hold Function, the hold measurement use the following rules
judge the reading count:
When Max() - Min() ≤ hold scope x ReadingN, the multimeter hold ReadingN on the
display.
The display update a new reading was based on the current value of reading and the
following three readings before the reading was hold:
Max (ReadingN, ReadingN-1, ReadingN-2, ReadingN-3)
Min (ReadingN, ReadingN-1, ReadingN-2, ReadingN-3)
NOTE
When reading hold started, the input resistance was automatism set to 10MΩ for all
DC voltage range. This set-up is conducive to reducing noise arising from the
open-loop testing.
