2.
Use the ,  keys to select the parameter to be modified, and the , 
keys to modify the parameter value.
It is not necessary to confirm the selection with ENTER
.
Func
The virtual Func key allows setting the measuring mode of
the instrument, which may be: CAL, AUTO, R+, R-
Lim
The virtual Lim key allows setting the maximum continuity
limit, which may have the following values: 1.00
, 2.00,
3.00
, 4.00, 5.00
3. Insert the blue and black connectors of the single cables into the corresponding input
leads N and P of the instrument. Apply the relevant alligator clips to the free ends of
the cables. It is also possible to use the remote probe by inserting its multipolar
connector into the input lead P.
4. Should the length of the cables provided be insufficient for the measurement to be
performed, extend the blue cable.
5. Select the CAL mode to compensate the resistance of the cables used for measuring
according to the instructions given in § 6.2.1.
6.
Use the arrow keys ,  to select the virtual Func key and set the desired
test mode by means of the arrow keys , .
It is not necessary to confirm the selection with ENTER

Before connecting the test leads, make sure that there is no voltage at
the ends of the conductor to be tested.
7. Connect the test leads to the ends of the conductor to be tested as in Fig. 6.
CAUTION
Always make sure, before any test, that the compensation resistance
value of the cables is referred to the cables currently used. In case of
doubt, repeat the cable calibration procedure as in 6.2.1.
8.
Press the GO/STOP key on the instrument or the START key on remote
probe. The instrument will start the measurement.
