4)
L (line wire), N (neutral wire) and E (earth ground wire) of the power supply input socket
should correspond to the power plug of the instrument.
5)
The instrument has been specially designed for decreasing noise jamming caused by the
input in AC power terminal, but it is also recommended to use it in the environment of low
noise. If noises cannot be avoided, install a power source filter please.
WARNING: To avoid injury to personnel and damage to the instrument resulting from electric
shock, do sure that the earth ground wire is safely grounded.
There is selector switch between 110V and 220V voltage besides the power
interface on the rear panel. Please switch correctly.

Environment
1)
Do not store or use the instrument where it could be exposed to many dusts, great vibration,
direct sunshine and corrosive gas.
2)
The instrument should operate under the temperature ranging from 0
℃ to 40℃, relativ
e
humidity of no greater than 80%. For high accuracy, use the instrument in the environment
above mentioned.
3)
For high accuracy, do not block the left air vent so as to ensure good ventilation.
4)
The instrument has been specially designed for decreasing noise jamming caused by the AC
power input, but it is also recommended to use it in the environment of low noise. If noise
cannot be avoided, install a power filter please.
5)
If the instrument will not be used for a long time, please place it in the original or a similar
packing box. The environment temperature should be kept in the range of 5
℃ to 40℃, an
d
the relative humidity should not be greater than 85%. The box should be located in an airy
room where it could be exposed corrosive impurities and direct sunlight.
6)
Test leads on the instrument that are connected to DUTs should be kept away from strong
electromagnetic fields to avoid interference.
1.6
Use of Test Fixture
Only use the test fixture or cable made by our company, because
the use of other test fixtures or
cables may result in incorrect measurement results.
In addition, for good contact of DUT and
fixture, keep the test fixture or cable and pins of DUT clean.
Connect the test fixture or cable to HI and LO terminals on the instrument front panel. Ensure the
color and arrow conformity of the test fixture with that of sockets on panels, thus to avoid
abnormal measurement.
