The product has calibrated before out of factory. After correctly wiring, it can be
powered and used immediately. But for further precise signal sampling, user needs to
warm-up the product for 3 minutes before use.
a)
The auxiliary power requires isolation voltage
≥
2000V
AC
, DC current output ripple
<
10mV, and multiple converters can share with one set auxiliary power together.
b)
Output signal (Iz) is designed to follow the impedance load value of
250
Ω
;
When
Resistance (R
1
) is less than
100
Ω
,
the user must add output current circuit a power
reduced resistance load R
0
to keep the summation of total impedance value is
between
100
Ω~
250
Ω

Basic testing method for accuracy
(1)
According to the terminal definition table to connect the testing circuit;
(2)
The testing must to be done by under the following conditions
