4 Attach the test leads to the circuit or the appliance under test (see Figs 20 & 21)
5 If the “Live Circuit” warning is displayed on the LCD and/or the buzzer sounds, do
not press the test button but disconnect the instrument from the circuit. Make the
circuit dead before proceeding.
6 Press the test button, the display will show the insulation resistance of the circuit or
the appliance to which the instrument is connected.
7 Note that if the circuit resistance is greater than 20MΩ, the instrument will autorange
to the 200MΩ range. If it is greater than 200MΩ at the 500V or 1000V range, it will
autorange to the 2000MΩ range.
8 When testing is complete release the test button before disconnecting the test leads
from the circuit or from the appliance. This will ensure that the charge built up by the
circuit or the appliance during insulation test is dissipated in the discharge circuit. In
the discharging process, “Live Circuit” warning will be displayed on the LCD and the
live circuit warning buzzer will sound.
