1.4 Power Connection
1) Power supply: 198 to 242Vac (50Hz).
2) Power supply power range: ≤50VA.
3) 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.
1.5 Fuse
The fuse is a standard configuration, so use the included custom fuse please.
1.6 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 10℃to 40℃,
relative humidity ≤90%. For high accuracy, use the instrument in the environment as
mentioned above .
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 is not used for a long time, place it in the original or a similar packing.
The environment temperature should be kept in the range of 0°C to 40°C, and the
relative humidity should not be greater than 90%RH. The box should be located in an
airy room where it is not exposed to 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.
1.7 Use of Test Fixture
It is recommended to use the test fixture or cable supplied with instrument, 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 HV (-) and INPUT terminals on the instrument front
panel.
1.8 Warm-up
1) For accurate measurement, the warm-up time should be at least 30 minutes.
