Lo Measurement; Insulation Resistance - Beta 1760/OHM Manual Del Usuario Y Operador

lo measurements
1 Set the function switch to the 50Ω/200mA position.
Insert the black test lead banana plug into the negative insulation- jack. Insert the red
2
test lead banana plug into the positive jack.
3 Connect the tips of the test leads to both ends of the circuit under test. Read resistance in Ω
on the LCD. The two ranges (50.000/500.00Ω) can be switched automatically; the primary
display of the resistance, in Ω, flashes simultaneously with the analogue bar.
4 When the impedance on circuit is below approximately ≤35Ω, it will be signalled by a con-
tinuous sound of the beeper.
5 The current ranges from 200 to 220mA while the tested resistance is 0Ω
insulation resistance measurements
1 Set the function switch to the 50~1000V/5000MΩ position.
2 Press the ranGe key to scroll through the available voltages until you select the desired
voltage. You can choose 50V, 125V, 250V, 500V and 1000V. There are 4 ranges, namely 4MΩ,
40MΩ, 400MΩ, 4000MΩ, which can be switched automatically for every voltage-block.
3 Primary display shows insulation resistance, expressed in MΩ, synchronized with analogue
bar. The left auxiliary display shows current insulation voltage output measurement, the RH
auxiliary display shows setting insulation voltage output measurement, expressed in V.
