Operation Environment
(1) The Please do not operate the instrument in places where there is dusty, vibrant, under
direct sunlight, or where there is corrosive air.
(2) In order to maintain good measurement accuracy, the U2810D must be operated under
the following environment conditions:
Temperature: 0
°
C ~ 40
°
C
Humidity:
≤
75% RH at 40
°
C.
(3) The instrument is carefully designed in order to reduce the disturbance induced by AC
power supply, however, low noise environment is recommended. Sometimes a power
source filter is needed.
(4) Please store the instrument in the place where the temperature is between 5
°
C and
40
°
C, humidity is less than 85% RH. If the instrument will not be put in use for a time,
please have it properly packed with its original box or a similar box for storage.
(5) The instrument, especially the test leads, should be kept far away from strong
electromagnetic field to avoid interference with measuring precision.
1.5
Use Test Fixture
Original test fixture and test clip leads should be used in order to ensure correct and
accurate measuring results. At the same time, test fixture, test clip leads and pins of DUT
should be kept clean in order to connect well between DUT and test fixture. Test fixture and
test clip leads are connected to Hcur
、
Hpot
、
Lcur and Lpot 4 terminals on the front panel.
For DUT which has shield, please connect the shield to the ground terminal “
” of the
instrument.
1.6
Warm-up and Continuous Working Time
Warm up the instrument for a minimum time of 15 minutes in order to ensure measuring
precision.
Continuous working time should be less than 16 hours.
