Reading hold (autosettle)
With hold enabled (HOLD annunciator on), the first processed reading becomes the
“seed” reading and operation loops back within the device action block. After the next
reading is processed, it is checked to see if it is within the selected hold window (0.01%,
0.1%, 1%, or 10%) of the “seed” reading. If the reading is within the window, operation
again loops back within the device action block. This looping continues until the specified
number (2 to 100) of consecutive readings are within the window. If one of the readings is
not within the window, the instrument acquires a new “seed” reading and the hold process
continues.
When a hold reading is acquired, an audible beep is sounded (if enabled) and the reading
is considered a “true measurement.” The reading is held on the display until an “out of
window” reading occurs to restart the hold process.
For remote operation, the hold process seeks a new “seed” once it has been satisfied and
the reading has been released. For basic front panel operation, the hold process does not
seek a new “seed” until the held condition is removed.
NOTE
Hold cannot be used when scanning.
