To Use Reading Hold
The reading hold feature allows you to capture and hold a stable reading on the
display. When a stable reading is detected, the meter emits a beep and holds the
value on the display.
– Reading hold has an adjustable sensitivity band to allow you to select which
readings are considered stable enough to be displayed. The band is expressed
as a percent of reading on the selected range. The meter will capture and
display a new value only after three consecutive readings are within the band.
– The default band is 0.10% of reading. After enabling reading hold, you can
choose a different band by pressing
(Menu Recall). This takes you to
the “READ HOLD” command in the TRIG MENU (only if reading hold is
enabled).
Go down to the “parameter” level, and then select a value: 0.01%, 0.10%,
1.00%, or 10.00% of reading.
– The sensitivity band is stored in volatile memory; the meter sets the band to
0.10% of reading when power has been off or after a remote interface reset.
