4. Measuring and testing
4.1. General information
The
upper display line
shows currently selected
measurement range.
When this indication is
flashing you have to con-
nect special accessories
e.g. TMZ or MZ
The
lower display line
shows the actual
metered value.
The instrument is switched off automatically
approximately 60 seconds after the last
measurement in order to extend battery life. In the
display the indication „off“ appears (exception: see
section 4.6 frequency measurements). The backlight
turns off when no measurement result is applied or
when the battery is low.
With the ON/OFF button engaging the
METRALINE EXM25 to voltage, call the
display test and switch-off the device.
With the function button you can select
