6.3 Modifying the parameters
After having displayed the first parameter, either type C or type F, proceed as follows:
1. press or to reach the parameter which needs to be modified;
2. press
to display the associated value;
3. increase or decrease the value using the
or buttons, until the required value is displayed;
4. press
to temporarily save the new value and return to the display of the parameter code;
5. press
or again to reach the next parameter which needs to be modified; repeat the operation from point 2.
6.4 Saving the new values assigned to the parameters and exiting
Press the
button for 5 seconds to definitively save the new values.
IMPORTANT WARNING: only pressing the
button for 5 seconds moves from the temporary to the definitive saving of the
modifications. Therefore, if power is disconnected from the instrument before pressing
, all the modifications made and
temporarily saved will be lost.
6.5 Exiting the procedure without modifying the parameters
1. do not press any button for at least 60 seconds (exit by TIME OUT). In this way, the instrument returns to normal operation
without saving any of the modifications to the parameters.
2.
select the parameter PS, enter using
and when the value displayed is 00 press
again.
