in calibration when you use it by current input.)
*3,4
F377A and the device connected should be grounded when you use them. (Usually, one
side of shield wire should be connected to avoid the cause of faulty operation by forming
ground loop. However, when high frequency noise affects the operation, it will be
improved by connecting both sides of the shield wire.)
*5
Usually, there is no need to wire A. GND, but it causes the fluctuation of the indicated
value when the potential difference between A. GND terminal and A. GND terminal of
the device connected is produced .
In this case, the symptom may be improved by connecting A. GND to AGND of the
device connected.
*6
F377A is a high resolution type indicator which can perform A/D conversion at supper-
high speed. The wiring between F377A and device connected should be in the short
distance to eliminate the effects of induction noise. Moreover, the connection should be
apart from AC power source and wiring of large volume current. Conduct adequate
checking before the operation.
