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
Shift >
(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.
