Freezing the mea-
sured value (HOLD
function)
With the HOLD function, you can freeze the current measured value. The dis-
played measured value stops changing until you switch the HOLD function off.
Stability control
(AutoRead )
The stability control function (
AutoRead
) continually checks the stability of the
measurement signal. The stability has a considerable impact on the reproduc-
ibility of measured values. The display of the measured parameter flashes until
a stable measured value is available.
You can start a measurement with
Stability control
manually at any time, irre-
spective of the setting for automatic
Stability control
(see section 11.6.3) in the
System
menu.
