4.2.2 Measurement Sample
The primary measurement sample action is a measurement. However, the measurement sample action
block could include the following additional actions:
Hold — with hold enabled, the first processed reading becomes the “Seed” reading and operation loops
back within the measurement sample block. After the next reading is processed, it is checked to see if it
is within the selected window (0.01%, 0.1%, 1% and 10%) of the “seed” reading. If the reading is within
the window, operation again loops back within the measurement sample block. This looping continues
until the specified number (2 – 100) consecutive readings are within the winder. If one of the readings is
not within the window, the instrument acquires a new “seed” reading and the hold process continues.
4.2.3 Reading Hold
When a hold reading is acquired as described in “Measurement Sample”, 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. The reading hold feature allows you to
capture and hold a stable reading on the display.
Take steps below to enable and set reading hold function.
