7. Operating specification
(1) Safety notices
a. There is a possibility of causing an accident of electric shock. After the measurement of
insulation resistance is completed, be sure to discharge the high voltage charged in the
measuring object.
b. There is a risk of electric shock during the measurement. Be careful not to touch the
measuring terminal and measuring object during the measurement.
c. When the circuit is activated, make measurement after disconnecting the power
source.
d. Make measurement within the insulation resistance measuring range, and never
impress voltage from outside, or the tester will be destroyed.
e. Be sure to confirm the position of rotary switch and the connection of measuring lead
with the tester before starting the measurement.
f. When start the high voltage startup switch, there is a high voltage about 100V
～
5000V
between
L
and
E
, must not touch the bare part of meet and object be tested cause of the
danger of been shocked.
(2) AC voltage test
a.
Don’t test up AC 750V voltage. It is Dangerous!
b. Connect the measuring Leads
Insert the red plug of lead with
probe to measuring terminal “
V
”, and the black plug of
AC measuring lead to measuring terminal
“
COM
”, respectively.
c. Connect to the measuring object
Using the rotary switch select the “
750V
” position. Connect the test pin of lead with
probe to the other side of measuring object, and the test pin of AC measuring lead to
