Press the up or down key to change the value of “SP”. Once the desired

the present reading. If anything else shows on the display, leave it alone for
1 minute, until the display returns to normal.
Three options are available when accessing the instrument parameters.

shows r.P. Press P and the display shows “0”. Use the DOWN keys to set
the password -281. If you pass -281 then use the UP key to get back.
Once the correct password is entered press the P button again and the
display will show the first parameter “S.LS”.
Using the UP and DOWN keys, the desired parameter can be selected and
pressing the P key, the display will alternately show the parameter code
and its setting that can be changed with the UP and DOWN keys.
Once the desired value has been set, press the key P again: the new value
will be memorised and the display will show only the code of the selected
parameter.
Pressing the UP and DOWN keys, it is possible to select another
parameter and change it as described.
