5.3.2. R ISO MEASUREMENT
Measured quantities and display ranges:
Insulation resistance R
INS 0  100 M (test voltage 100 V)
0  250 M (test voltage 250 V)
0  500 M (test voltage 500 V)
0  1000 M (test voltage 1000 V)
Test voltage U test 0  1100 V
1) Select M  function by pressing the FUNC hard key first.
2) Check selected test voltage (100, 250, 500 or 1000V) and modify it if needed by pressing the Utest
(5) touch-screen key first.
3) Check selected mode and modify it if needed by pressing the MODE (6) touch-screen key first.
MANUAL, TIMER or AUTO mode can be selected.
