NOTE
･ Insulation resistance is the ratio of leakage
current to applied voltage, and is therefore
unstable. Depending on the circuit being
measured the needle may not stabilize, but
this is not a meter malfunction.
･ While measuring there may be an oscillator
noise from the meter, but this is not a
malfunction.
･ When measuring insulation with respect to
ground, or if the circuit to be measured is
grounded, connect the EARTH probe to the
ground side. This may decrease the
measured value slightly, but is satisfactory
for checking insulation.
･
When the object being measured contains a
capacitance component, the needle may first
indicate a value lower than the actual
resistance value immediately after the
MEASURE
switch is pressed. After that the
actual resistance value is indicated.
･ Press the MEASURE switch fully down until a
click is heard. If the switch is not pressed
down fully, the needle will not move from
∞
and a proper measurement cannot be made.
