5. Operation
The instrument is powered by activating the
switch marked
‘POWER’
.
Immediately on power-on the instrument dis-
plays the version number (i.e. ‘r 1 1.00 .00 .00’
for approx. 2 secs.).
The counter is now ready for use.
The selected function and method of measure-
ment are shown in the LCD-display.
To change language turn off the power, hold the
‘SELECT’
and simultaneous switch on the power.
Use the
‘SELECT’
button to change the lan-
guage, press
‘FUNCTION’
to store the selection
in memory.
Select a function with the push-button
‘FUNC-
TION’
and then the measuring method with the
pushbutton
‘SELECT’
.
If the selected function has the option to select
the trigger polarity, then a simultaneous push on
‘FUNCTION’
and
‘SELECT’
displays the trigger
polarity in the LCD-display for each input.
Pushing the
‘SELECT’
changes the trigger po-
larity. Push the
‘START/STOP’
to store the se-
lection in memory.
