AUTO-HOLD
• When the rotary switch is set to Ω+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.
