1. Press the
MENU
key, move the cursor to
M
in the main
menu by means of the arrow keys (

) and confirm with
ENTER
. Subsequently, the instrument displays a screen

2. Use the
,
keys to select the parameter to be modified, and the
,
keys to
modify the parameter value:
MODE
This key allows setting the test mode. The following options are
available:
MAN, TMR, AUTO
.
Vtest
This key allows selecting the DC test voltage generated during
measurement. The following values are available:
50V, 100V, 250V, 500V, 1000V
.
Lim
This key allows the selection of the minimum limit threshold in order to
consider the measurement correct. The following values are available:
0.05M
,
0.10M
, 0.23M
, 0.25M
, 0.50M
, 1.00M
, 100M
.
FUNC
This key allows setting the connection type L-N, L-PE or N-PE in MAN
mode.
Temp
Only in TMR mode, this virtual key allows setting the duration time of test
in the range:
3s ÷ 999s
.
3. We suggest setting the value of the voltage supplied while measuring and the
minimum limit to consider the measure correct according to the prescriptions of the
reference standard (see § 12.2).
4. Insert the green and black connectors of the single cables into the corresponding
inputs B1, B3, B4 ( MAN and AUTO modes) or B1, B3 (TMR mode) of the instrument.
Apply the relevant alligator clips to the free ends of the cables. It is also possible to use
the remote switch probe by inserting its multipolar connector into the input B1. Should
the length of the cables provided be insufficient for the measurement to be performed,
extend the green cable.
