# DANGER
● Do not touch the circuit under test just after finishing a measurement. The
charged potentials may cause electrical shock hazard.
● Do not touch the circuit under test and also not to remove the test leads
until a discharge completes.
● Check with a High Voltage Detector that there is no electrical charge exists
on the circuit under test.
● Be sure to put on a pair of insulated gloves for high voltage.
● Be extremely careful not to get electric shock during insulation resistance
measurements and the Test Button is being pressed as high voltage is
present on the tip of test leads and on the circuit under test continuously.
● Do not make measurement with the Battery Cover removed.
● Do not make measurement when thunder rumbling.
# CAUTION
● When the live circuit warning is indicated or the warning buzzer sounds,
measurements cannot be made even if the Test Button is pressed.
To check the insulation of electric equipments or electric circuits, measure
their insulation resistances with this instrument. Be sure to check the
voltage which can be applied to the equipment under test before making
a measurement.
Measurements automatically stop, when battery voltage becomes too low
to ensure accuracy of readings, while the instrument is operating with a
battery. In this case, the instrument performs auto-discharge and displays
warning for low battery voltage as shown below. Then LCD becomes blank.
