&
AUTO-HOLD
• When the rotary switch is set to
W+A:
- Freezes the displayed measurement for as long as the HOLD button
is pressed. The NOISE, clamp open (
), and alarm exceedence ( )
icons are visible, if they were active.
• AUTO-HOLD Function:
If the AUTO-HOLD mode was enabled during instrument SET-UP (see
§ 4.4, menu #11), opening the clamp acts as the identical state to the
HOLD mode for as long as the clamp is open. The benefit of this function
is that it makes it easy to freeze the measurement with one hand, when
access to the HOLD button is difficult.
If the HOLD button is not pressed during this time, closing the clamp
automatically exits the AUTO-HOLD mode.
