Conditions of
Use:Temperature -25 ~ + 40 ℃, relative humidity
less than 80%
Crank rated speed:120r/min
Dimensions:10*10*8
Weight:5LB
Before use, the first to do in the following
preparations:
(1) measuring equipment to be tested before the
power cut off, and to short-circuit discharge,
never allow live measurement equipment to ensure
the safety of persons and equipment.
(2) the possible induction of high-voltage
equipment, the need to eliminate this
possibility can be measured.
(3) the measured surface to clean, reducing the
contact resistance, to ensure the accuracy of
measurement results.
(4) before the measurement to check whether
megger in normal working condition, mainly to
check its "0" and "∞" two points. That shake the
handle, the motor rated speed, short circuit
megger should refer to the "0" position, should
be open refers to "∞" position.
(5) megger should be used on a stable, solid
place, and away from the large external current
conductor and an outer magnetic field.
Do the preparatory work, it can be measured, and
in the measurement, but also pay attention to
correct wiring megger, otherwise it will cause
unnecessary errors or mistakes. |
1.insulation resistance
table when not in use to put in a fixed cabinet,
ambient air temperature should not be too cold
or too hot, should not put the waste on the wet
ground, and to avoid the corrosive effects of
air containing place (such as acids, alkalis
steam, etc.) into.
2.should try to avoid severe long-term
vibration, so the header pivot and jewel damage
and affect the scale indication.
3.terminal wire connections between the measured
object can not be used with wire, should be
separately connected, not because of poor
insulation and twisted affect the reading.
4.before and after taking measurements of the
measured object must be fully discharged, to
ensure equipment and personal safety.
5.when lightning or tape device near high
voltage conductor prohibited measuring
insulation resistance meter, only in the device
is not charged and can not be carried out when
other power by induction charging.
6.when the switch from slow gradually shaken
handle fast, if found pointer zero allowed to
continue to vigorously shaken to prevent coil
damage. |
