Hold measurement
The hold feature allows you to capture and hold a stable
reading on the front panel display.
When a stable reading is detected, the multimeter emits a
beep (if the buzzer is enabled in the utility menu) and holds
the reading on the primary display.
Figure 2-2 Accessing hold measurement
When enabled, the hold operation turns on the hold
annunciator and begins evaluating readings using the rules
described below:
Primary Display = Reading
N
IF Max() – Min() ≤ 0.1% × Reading
N
The decision to update a new reading value in the primary
display is based upon the box- car moving statistics of the
present reading and the three previous readings :
