3.4.3 Read Hold
Read Hold mode can capture and hold the stable readings on screen, used to sample a
reading and hold the reading on screen since after moving the probes. Multimeter beeps once
catch one stable reading and keep the reading on display (if front panel beep is on).
User can set the sensitivity range for this mode, to determine the reading whether is stable
and also show it. The range is indicated by percentage of readings. Only three continuous
readings are all within the range, multimeter capture and display the new reading. Sensitivity
range: 0.01%, 0.1%, 1.00% or 10% of reading. For example, if you select 1.00% as range,
and input signal 5V. Once the continuous three reading are all within the range from 4.975V
to 5.025V, multimeter will display the new reading.
